The best drainage pumps for dirty water: reviews. How to choose a drainage pump for dirty water? Dirty Water Submersible Drainage Pump Best Dirty Water Submersible Drainage Pumps

There are several types of submersible pumps. These can be both conventional well models for pumping water into the water supply system, and drainage samples, which are necessary for more highly specialized tasks.

It is about drainage pumps for pumping water that will be discussed now.

1 Purpose and features

Standard pumps are engaged in pumping water from wells or clean sources. Their task is simple and trivial, but without the regular performance of these functions, one cannot imagine any in a modern house.

Drainage pumps perform slightly different functions. They are intended for pumping contaminated liquid. That is, the fluid that somehow interferes with you and must be pumped out.

There are many useful examples. Rising groundwater levels alone regularly flood huge amounts of basements and drainage systems with polluted liquid. Removing it from there manually is very difficult. You will have to spend a huge amount of time and effort, and the result is unlikely to impress you.

If you use a submersible mud pump, then it will cope with the same work on its own and, without exaggeration, ten times faster. There are problems in other areas of human life. Very often, sewerage is clogged in areas, especially if it was not laid according to all standards and could not maintain the correct degree of slope or angle of rotation.

Canals of drainage systems can also become clogged, this often happens during the rainy seasons, when too much water washes away the soil. If it is not removed on time, then this will become a problem for your well or well, as this liquid needs to go somewhere.

2 Types and differences

Drainage submersible pumps are in themselves a type of equipment that is used to pump water. However, from the lines of this equipment, there are several interesting varieties that should be considered.

So, drainage models according to the type of working environment are divided into samples for interaction with:

cold liquid;
hot liquid.

This is a rather important point, since not all devices are able to work with. The fact is that the drainage pump must be located directly in the working environment.

Moreover, he must be there constantly, all the time while work is in progress. Accordingly, the case is affected not only by an aggressive environment from a dirty liquid, but also by a hot temperature, and, as you know, it can even melt or break the integrity of cheap polymers.

Another caveat is that the drain engine is prone to overheating. Moreover, it overheats, even being in a cold liquid. That is why it is recommended to deal with them very carefully.

The problem can be solved by purchasing more expensive pumps such as Grundfos, Park, Caliber or Karcher, but even these manufacturers are not able to guarantee you complete protection against overheating. The hot environment only exacerbates an already difficult situation.

It is with these parameters that the second presented type of pumps differs from the first. The first samples are mostly cheap or medium-priced devices made from common materials (for example,).

The latter are produced only by large companies such as Grundfos, Park or Karcher. They are assembled from high-quality plastic and metal, equipped with good protection against overheating and, in general, are much more productive than their counterparts in appearance.

According to the type of protective element, they are divided into:

Devices without protection;
Devices with filters;
Shredder devices.

Representatives of the first class in our time are rare. These are rather pumps that, due to their features, do not pay attention to waste in the working fluid. The latter are protected by mesh. This is the most common class of drains.

Still others are not so directly related to drainage models. They are equipped with chopping mechanical knives, but as a rule, they already belong to fecal samples. The line between them is quite thin, but it exists and must be taken into account.

2.1 Popular manufacturers

Drainers for dirty liquids are produced quite widely. In the modern market, they are represented by a huge number of companies and possible variations. However, we will now highlight only a few of the most popular and really noteworthy manufacturers. We have already mentioned them above - these are pumps from:

Grundfos;
park;
Caliber;
Karcher.

Grundfos has been in the market for pumping and plumbing equipment for a very long time. Grundfos products are hugely popular all over the world, and for good reason. A similar situation exists with pumping equipment, in particular, with drainage pumps.

Grundfos drains boast exceptional quality, durability and reliability. At the same time, the price of equipment from Grundfos, although it is at a fairly high level, still allows it to compete with other manufacturers.

The same is true with Karcher. However, the Karcher brand is much more recognizable. After all, this is a German company with a huge name and a long history. The guys from Karcher create drainage pumps in a plastic shell. They are extremely reliable and productive, but also cost decently.

Park boasts the average performance of its equipment. However, this is what most buyers want. Not every person is trying to buy the most powerful sample of the pump, but by and large, he does not need it. But the products from Park just provide an opportunity to buy the unit that is optimal in terms of its characteristics and price.

Caliber products have a slightly different direction. The developer does not even hide that he is not able to compete in quality and power with leading brands. On the contrary, the Caliber company is trying to attract its customers with the practicality and, importantly, the cheapness of its products.

Caliber pumps are convenient in that they are easy to mount, repair, and in the event of a breakdown, they can be replaced with new ones without a serious blow to the wallet.

At the same time, we still note that the equipment from the Caliber company is not bad. It's just that Caliber pumps are spared a huge amount of fashionable bells and whistles that are inherent in models from world brands such as Grundfos or Karcher. These are workhorses, which, however, perfectly cope with their tasks.

2.2 Installation technology for submersible drainage pumps

Installing modern submersible type drains is very easy. They are specially designed and thought out so that the installation process takes extremely little time.

All that is required of you is to install the pump in the working plane, after connecting the hose and electricity to it. It is also necessary to use a float switch, which automatically blocks the engine when the water level drops critically.

As a rule, switches are already connected to the pump, but this is not always the case. After that, it remains only to hang or install the unit in the working plane.

If you decide to put it on the bottom, then it will not be superfluous to do it on some kind of plate or something like that. In this case, you will get rid of potential problems that are associated with the suction of stones and other objects from the bottom by the drainer.

2.3 Overview of the drainage pump from Karcher (video)

Drainage pumps pump out water for us from pits, low-yield wells, basements, tanks for irrigation and cleaning of territories. On a suburban area, they have a lot of important functions that drainers can handle only with proper selection. Agree, there is little benefit from a device that is not used due to technical limitations.

We tell readers of the site in detail how to choose a drainage pump. We analyze what kind is required to perform a certain job. Here you will learn all the subtleties and technical criteria, according to which a suitable drainage pump model is determined.

The article presented for review lists all the factors that ensure an error-free choice. Popular drainage pumps are given as an example and described in detail, the quality of which has been verified by practice. The information content of the text is supplemented by photo and video applications.

Initially, these devices were created for pumping water from basements flooded with water. Later, the area of use expanded. Modern models are designed for pumping lightly contaminated liquids from pits, wells, pools, pumping and cleaning wells.

In addition, they are used in production, included in the technological process. Most devices are capable of pumping liquids with impurities of about 10 mm in size.

Drainage pumps are specific equipment designed for a rather narrow range of work. It is not recommended to use it for other purposes. Despite the fact that drainers are used in shaft wells, they are not intended for permanent work in them.

The devices cannot work as a fecal pump either, although some "craftsmen" are trying to replace them.

Drainage pumps are designed for pumping and pumping clean or slightly contaminated liquids, can be used for draining small ponds, pumping and cleaning wells

Drainage equipment can only work with lightly contaminated liquids. The amount of solid impurities, depending on the type of apparatus, varies from 3 to 40 mm.

The mechanism is used for pumping water from wells, ponds, basements, etc. The "weak" point of the device is the holes in the bottom, which are often silted up, since the device is installed on the bottom of a reservoir or tank. This drawback is less inherent in models in which the suction holes are located in the upper part of the case.

Criteria for the right choice of equipment

For those who make a brief review and evaluate the selection criteria, we have given the main ones.

Characteristics of the pumped medium

Before buying a pump, you should determine which liquid it will have to pump out. It should be relatively clean, free of stones, high levels of mud or sand, and free of bottom sediments of silt.

These can be flooded rooms or basements, tanks filled with rainwater, wells, ponds, etc. If the pump is to be lowered into a pond, it must be on a solid bottom.

For each model of a submersible drainage pump, the accompanying technical documentation indicates the maximum amount of impurities that the device can pass without loss of performance.

Therefore, it is installed in a suitable vat, bucket or on a special base plate. Each model is designed to work in a specific environment, that is, it indicates the maximum size of impurities dissolved in the liquid that the mechanism can pass without reducing its performance.

Image gallery

Depending on the contamination of the liquid, all drains can be divided into groups:

For lightly contaminated or clean liquids with impurities up to 5 mm.
For liquids of medium degree of pollution with inclusions not exceeding 25 mm.
For polluted, melted or rain water. Permissible particle size of contaminants is from 25 to 38 mm.

In addition to the size of impurities, it is also important to take into account the temperature and chemical composition of the pumped liquid. Aggressive compounds can damage the pump, so you need to know exactly what its elements are made of.

Materials used in manufacturing

The service life of the drainage pump directly depends on the material that is used to make its elements. The body of the device can be made of plastic or metal.

In the first case, the cost of the device will be lower, which is more attractive to the buyer. However, the plastic case is not sufficiently resistant to mechanical damage and often cracks or deforms.

For a drainage pump, it is optimal to have a metal case. It withstands quite large loads and does not crack. In addition, it is almost always repairable.

In this case, it is no longer repairable. Metal housings are more durable and maintainable, so pumps in this design last much longer.

One of the best housing materials is cast iron and stainless steel, which can work in almost any environment. Another important detail is the material from which the pump blades are made.

They can be made of stainless steel or a special technical polymer. In this case, the second option would be preferable. Special impurities that are present in the composition of the polymer make it more resistant to aggressive environments and mechanical stress.

A significant drawback is that they cannot be repaired. Blades made of metal wear out faster than plastic ones, so they are cheaper.

Type of circuit breaker

Almost all modern drainage pumps are equipped with automatic switches that start the mechanism when a predetermined level of the pumped liquid is reached.

The device can be:

Electronic built-in. Quite a complex and expensive node.
Poplavkov. A simpler, more reliable and inexpensive element.

Automatic switches of any type exclude the possibility of dry running of the pump, which prevents its serious damage.

Float type automatic switch. When the liquid level rises, it floats and turns on the pump and vice versa. Extremely simple, efficient and reliable device

Drain pump performance

Performance is understood as the amount of liquid, measured in cubic meters, that the device can pump in one hour of operation. This indicator must be indicated in the device passport. You can determine the required performance by dividing the volume of the reservoir from which the liquid will be pumped out by the estimated operating time.

On average, for home use, a mechanism with a capacity of about 10 cubic meters is quite enough. m/hour. For professionals, models with a capacity of 100 cubic meters or more are suitable. m/hour.

The pressure of the device for pumping water

It can vary in the range from 5 to 50 m. The magnitude of the pressure depends on the type of pump, which determines the distance to which water is discharged, or the height of the pumped liquid.

These indicators are indicated in the technical documentation. They are related to each other in a ratio of 1:10. Thus, if the passport indicates that the pump can lift liquid to a height of 5 m, then it can also transfer it to a length of up to 50 m.

It is clear that these are average figures that do not take into account any other parameters, for example, the diameter of the hose. Therefore, for clarification, you should contact the seller. For the most general calculations, you can use such data.

For household models, it will be quite enough if the pressure indicated in the technical documentation exceeds the calculated one by 3 m. If a powerful influx of water is expected or there is a lot of it, the “reserve” of the pressure should be greater.

Productivity and pressure are the most important characteristics that determine the choice of a drainage pump. Experts recommend using special charts developed by manufacturers to accurately select a device.

Outlet diameter

For maximum efficiency of the pump, the dimensions of the outlet nozzles must be accurately selected. If water is to be pumped, a small diameter model of 0.5 to 1.5 inches will do.

In the case of pumping contaminated liquid, it is better to choose an 8-inch or even larger option. In addition, branch pipes are available for horizontal and vertical connection. You need to choose the right type of model.

And a few more important points. The hose that will be connected to the outlet must have the same diameter. For domestic needs, it is worth choosing portable lightweight models. They are more mobile and convenient to use.

It is worth asking about the residual level of liquid that remains after the operation of the drainage pump. If you want to pump out water “dry”, you should choose a model that leaves no more than 2 mm of liquid.

Brand models of pumping equipment

#one. Italian brand Pedrollo

The company declared itself in the 70s of the last century. She quickly gained popularity with the high quality of her products, which is successfully combined with a very reasonable cost.

Today Pedrollo is one of the leaders in the production of pumps of various types. The range of drainage devices of this company is quite wide. In it, one can single out a particularly sought-after series of TOP.

These are drainage submersible units with an open centrifugal impeller. Designed to operate in automatic mode to lift and draw fluid without abrasive particles. The pump casings of this series are made of glass fiber reinforced technopolymer, which gives them increased impact resistance. The impeller and suction grate are also made of technical polymer.

One of the most popular models in the series is the Pedrollo TOP Vortex. As with all pumps in the TOP range, the structural elements of the device are made of a "proprietary" technopolymer.

This allows it to work in various aggressive environments and pump not only water, but also chemical reagents. The device is intended for pumping dirty liquids and fecal effluents, the size of the solid fraction in which does not exceed 20 mm.

The model is designed for continuous use, capable of functioning in partial immersion mode, equipped with an emergency shutdown device. This is a fairly powerful drainage pump, extremely easy to use.

Purchased to remove water from garages, basements, pools. It can be used for watering the site and even for organizing a small fountain.

# 2. Russian pumps Gileks

The domestic manufacturer began to supply its products to the market in the 90s of the last century. Dzhileks brand pumps are in great demand due to their adaptation to Russian operating conditions.

For example, they are not so sensitive to frequent voltage drops in the network. In addition, they are of high quality, and their cost is an order of magnitude lower than that of imported counterparts.

In addition, our country has a well-developed network of Gilex service centers, which guarantees no problems with repairs and spare parts. Drainage pumps of this brand are represented by a line under the general name Drainage.

These are submersible devices of various capacities, made of special plastic or stainless steel. They can function in environments where the size of the contaminants is from 5 to 40 mm.

The devices are economical and have a long service life. One of the most demanded models of the line is Drainage 200/10f. This is a fairly powerful pump with a immersion depth of up to 8 m.

The device is economical, its rated power is 880 watts. The device is equipped with a float switch, the operation of which can be adjusted by the user.

The drain pump has a high-strength plastic housing and is equipped with an overheating protection system. Among the advantages of the device, you can add the ability to operate for a long time in the mode of partial immersion. It can be used for drainage of wells, reservoirs, sewer sedimentation tanks, etc. The cost of such a device is quite democratic.

#3. German quality from Karcher

The time-tested German manufacturer Karcher produces reliable and durable drainage pumps. They are excellent for pumping even large volumes of liquids, as some models have a capacity of 18,000 l/h.

The easily recognizable Karcher brand drainage pumps are distinguished by high build quality, power, performance and long service life.

The Dirt series is designed for pumping dirty water, the size of impurities in which does not exceed 30 mm. Pumps from this range are perfectly designed to work in ponds or flooded cellars, basements. Karcher offers drainage pumps with a residual liquid level of no more than 1 mm. They pump water almost dry.

For pumping clean or slightly contaminated liquids, the manufacturer offers the Flat series. These devices can be installed in pools or drainage wells. The peculiarity of the line is that the devices leave a layer of water no higher than 1 mm, that is, they pump out the liquid almost dry. Karcher pumps are equipped with an intelligent level sensor with an adaptive algorithm.

This allows the instrument to respond almost immediately to liquid contact and adapt to changing operating conditions over time. The SP 3 Dirt model has earned high praise from consumers.

This is a fairly powerful device for pumping dirty liquids with inclusions no larger than 20 mm. It is equipped with a float switch and a ceramic-granite gland, which significantly increases the life of the device.

#four. Inexpensive drainage pumps from PATRIOT

Garden equipment of the American brand Patriot appeared on the domestic market in 1999. The company sells equipment and tools under its own brand.

The products are characterized by an attractive ratio between cost and quality. There are four samples in the line of drainage pumps. One of the most popular models is the PATRIOT F 300, which is distinguished by its low price and good performance.

Dirty water pumps of the Patriot brand are distinguished by an attractive ratio of affordable cost and high quality.

The device works with dirty water with inclusions no larger than 5 mm in diameter, equipped with a float switch. The pump can be lowered into the pumped medium to a depth of not more than 5 m. The throughput of the device is 3.5 m 3 / h.

At the same time, it has rather modest dimensions and relatively low power consumption. The drainage pump is easy to maintain and can be used to work in a pond or well, weighing only 3 kg.

#5. Pumps for dirty water brand GNOM

Produced by the Moscow Pump Plant. In the line of drainage devices there are household and professional models. The devices are equipped with a built-in hermetically sealed electric motor.

Are intended for work with liquids with a density up to 1100 kg/m³. The allowable impurity size is 5 mm. Devices designed to operate in a liquid medium with a temperature of 35 to 60C are marked "T".

In the line of drainage equipment of pumps, one of the most popular varieties is the model 16-16. This is a submersible pump with a 1.1 kW electric motor. The head of the device is 16 m, the liquid supply is up to 18 m. Such characteristics make it possible to use the device for pumping sandy or clay water from deep trenches and pits, flooded basements of a large area.

Drainage pump GNOM 16-16D can be used to lower the level of continuous groundwater. In addition, the equipment is used for watering greenhouses, greenhouses and vegetable gardens. The throughput is 16 m 3 / h.

The device is equipped with an air release button, which speeds up its start-up and ensures stable operation of the device. I must say that many owners of private estates and cottages consider this particular model to be one of the best.

When choosing drainage equipment, it is important to clearly understand how it will be used. This is the only way to choose the model that is best suited for specific conditions. At the same time, it must be remembered that its service life directly depends on the quality of installation and operating conditions.

You can ask a question or tell about your own experience in the selection and use of a drainage pump in the block below. Please comment on the article. We or website visitors will be happy to answer.

Many owners of private houses have to solve the problem of pumping dirty water on their own. For example, when floods occur in the spring as a result of the melting of a large amount of snow, not every owner has the opportunity to use the services of utilities, because they are very expensive. But even with the help of buckets, it will not be possible to cope with a large amount of water, because in the first days of the flood it arrives much faster than it is scooped out.

The best option in this difficult case would be to use a drainage pump for dirty water. With the help of such a pump, you can pump out water not only from a basement overflowing with floods, but also from your own pool or ornamental pond located on a personal plot. By the way, a drainage type pump is quite suitable not only for pumping out dirty water, but also for watering the garden.

To this end, the pump is simply lowered into a nearby reservoir (if there is one), and water is pumped from there through a hose directly to the garden. It should be noted that borehole or well pumps are not suitable for this purpose, since dirty water is present in natural reservoirs, and such units are designed specifically to work with clean water.

It is for this reason that you should always have a drain pump for dirty water in your household. The purpose of this article is to provide readers with information on how to choose a drainage pump for dirty water.

main destination

Dirty water pumps are of the drainage type, and therefore their design and use is similar to the principles of operation of fecal pumps. If you want some tips on choosing a dirty water drain pump, be sure to watch this video:

However, there is a huge difference between these two pump models.

So, they are designed more for pumping liquids with a high degree of viscosity, in which fibrous inclusions are present. To pump out such liquids, fecal-type pumps are equipped with special knives that turn large inclusions into a homogeneous finely dispersed mass. As for solid inclusions in dirty water, they are categorically contraindicated for fecal pumps, since they can disable not only the cutting elements of the knives, but also the impeller (or rather, its working blades).
The situation is quite different with special pumps specially designed for pumping dirty water. They, on the contrary, cannot work when pumping liquids with fibrous inclusions, but water with solid inclusions can be pumped out without any problems. The device of the drainage pump for dirty water is such that it can be used to pump out dirty water, which will contain insoluble (or poorly soluble) particles (for example, sand, silt, pebbles of a certain size). All permissible parameters of such inclusions must be displayed in the passport attached to the product.

Depending on the model, the drainage pump is capable of operating with solid particles ranging in diameter from 5 to 50 mm. The design features of drainage pumps for dirty water determine the breadth of their scope, which can be as follows:

Spring floods, heavy snowmelt, prolonged rainfall. In this case, the situation may develop in such a way that storm drains will not be able to cope with a large flow of water. as a result of this, basement floors of cellars and basements of residential buildings will be flooded. A drainage pump in such a situation will help to carry out urgent drainage emergency work.
The dirty water drainage pump can be installed in the basement as a stationary device. If the automation is properly configured, it will carefully monitor the state of the groundwater level and constantly keep the room dry.
Maintenance of artificial reservoirs is another important task that a dirty water drainage pump can handle. If necessary, it is impossible to drain such a reservoir in order to clean or completely replace the water, or to maintain the required level of its filling without a high-quality drainage pump.
Prefabricated containers from a domestic or drainage sewer system, which do not provide for independent drainage of liquid. Periodically, dirty water is pumped out of them using drainage pumps. The water settled after such pumping is conducted to special filtration fields, centralized collectors or natural reservoirs. Sometimes this water is pumped into tanks for the purpose of its further use for technical needs.
Without local treatment systems, the premises of car washes and car repair shops cannot function normally. These are strict hygiene regulations. Dirty water in such systems is collected in primary collectors or pits, and it is pumped out from there using dirty water drainage pumps.
Dirty water fecal pumps have found their way into the agricultural environment as well. It is with their help that water is pumped from natural or artificial reservoirs to irrigated agricultural areas.
Dirty water pumps are known for their versatility. Manufacturers of such pumps create them for use in pumping and pumping dirty water, but nothing prevents the pump from being used for pumping clean water (for example, from a well or a well).
The pump for pumping out dirty water can also be used to fill containers located at high altitudes with clean water. These can be tanks or barrels that are part of the autonomous water supply system of residential buildings, installed on an outdoor shower or in a bath of a water tank.

In Photo #1, readers can see the dirty water drain pump in action.

At its core, the described pumps are characterized as drainage, and are designed to work with dirty water. However, it should be understood that there are many different models of drainage pumps with individual design features. In accordance with them, the specifics of the application are determined.

Accompanying documentation is attached to each model of the drainage pump, which necessarily indicates information on the size of the fractions with which the unit can work. The permissible composition of suspensions is also indicated in such documents.

For example, a drainage pump can pump dirty water that contains elements of inorganic origin (fibrous particles, threads, etc.), animal hair or hair. Such aggregates may well be singled out in a separate group. For domestic needs, experts recommend using drainage pumps capable of pumping water, which contains solid particles up to 10-15 mm in size.

Device

Any pump intended for pumping dirty water basically contains a power unit characterized by a certain level of power, as well as a working chamber, which creates the optimal working pressure for pumping liquid. The power unit is most often powered by electric current.

The device of the drainage pump will depend on its type and operating parameters. According to their principle of operation, such designs are divided into centrifugal, vortex and vibration type pumps.

The device of a centrifugal pump (which, by the way, belongs to surface-type structures intended for pumping contaminated water) is represented by the following elements:

Housing made of cast iron or stainless steel.
Impeller, characterized by an open type and also made of stainless steel or brass.
Connecting elements made of stainless steel or cast iron.
The main (leading) shaft, created from chromium-nickel or stainless steel.
The motor is single-phase, equipped with thermal insulation and external ventilation with parameters 2308-50 Hz.

Photo No. 2 shows a schematic of a drainage pump for pumping dirty water.

Drainage pumps of the vibration type are recommended mainly for pumping clean water, since they are characterized by a high level of sensitivity to various kinds of impurities. Most of the drainage pumps are characterized by a centrifugal type device.

The operation of the entire pump design is carried out in the following sequence.

After the start of the operation of the electric motor, the rotation from it is transmitted to the impeller.
Under the influence of pressure from the side of the impeller, water is thrown with force to the outer wall of the tank, as a result of which a high level of pressure is formed in the outlet pipe. In the working chamber (more precisely, before entering it), a whole system of valves is installed, which is necessary to prevent the backflow of dirty water.
Due to the presence of an increased level of pressure in the outlet part of the pumping line, a rarefaction is formed in the intake section of the drainage pump, which favors the effective absorption of water.

The design of the drainage pump is in a durable metal housing with excellent protective characteristics. Submersible drainage pumps are most often made of stainless steel, and surface pumping structures are made of composite alloys, steel or cast iron. If the pump model has low power, then the casing for it can be made of impact-resistant polymer material.

The device of the impeller of the drainage pump, the diameter of the internal channels of the pump, as well as the material from which this element is made, allow the entire structure to work smoothly, with the ability to pass solid particles of a certain diameter.

In order to prevent larger parts from entering the working structure, a protective mesh is usually installed on the pump inlet pipe, the cells of which have a certain size. If the pump is surface, then the mesh is installed on it in the inlet part of the intake sleeve.

In Photo No. 3, you can see a schematic representation of a drainage pump immersed in water.

As for the design of the element called the impeller, it may also have some differences depending on the pump model. Here are the main ones:

The most common scheme, in accordance with which the design of the pump impeller is carried out, is the one in which there is a single-channel impeller that allows pumping liquid with a high degree of viscosity.
The best option when it is necessary to pump large volumes of water would be drainage pumps with an open impeller. Such products will cope equally well with pumping heavily polluted water and pumping fecal effluents.
But if the power of the drainage pump is of great importance to you, then the best choice in this case is to purchase a device equipped with a vortex wheel (shifted slightly back, the so-called rotary type). True, this design has its drawbacks, the main of which are the high level of energy costs and the high cost of the pump.

The principles of operation with surface pumps are based solely on visual inspection. But submersible drainage pumps are often equipped with float sensors, which eliminates the need for constant and continuous monitoring of their activities. When equipping submersible pumps with controller sensors, manufacturers pursue at least two goals:

A properly debugged and well-tuned system will help to constantly maintain the optimal water level in the pumped tank. Such a device will avoid overfilling the tank and turn off (or, conversely, turn on) the drainage pump in time.
Automation will immediately respond in the event of any emergency. For example, it is with its help that the power supply is turned off in the event that the water level drops to critical levels, which causes the pump casing to open. Such situations, in the absence of automatic shutdown, often lead to burnout of the drainage pump and its failure.

Most of the models of drainage pumps are designed for pumping cold water with a temperature not higher than 35-40 ºC. If, according to the operating conditions, it is supposed to pump heated (hot) water, then the best option would be to choose a design with the appropriate parameters, which are necessarily indicated in the technical documentation for the device.

I would like to draw the attention of readers to another type of pump, which is more often used in construction when it is required to pump out groundwater from pits. Such pumps are called diaphragm pumps, and are mostly equipped with gasoline engines.

This is very convenient, since construction sites do not always have access to electrical energy. Models of membrane drainage pumps with a gasoline engine are installed by manufacturers on special platforms with wheels, which makes it possible to move the device from one place to another without any problems.

The device of the diaphragm pump is such that there are practically no moving parts in it that would create friction against each other during operation. And therefore, such models may well be used for pumping dirty water containing clay, pulp, and even small pebbles. This type of pump must be equipped with a reinforced suction hose.

When installing a membrane-type pump, its manufacturers provide for the possibility of diverting water from an excavated pit directly during construction work. The membrane model of the drainage pump for dirty water consists of the following elements:

A trench or ditch that functions as a drain.
Pit.
Lowering of the groundwater level.
Drainage loading.
Diaphragm type surface pump.
Inventory spacers.
Groove fastening.
Suction hose equipped with a protective filtration mesh. the height of this sleeve should not exceed 5-6 meters.

With the help of a membrane-type drainage pump, builders lower the level of high-lying groundwater during excavation work.

Pros and cons

The pros and cons of drainage pumps largely depend on their type. For example, the positive characteristics of surface pumps include:

High degree of mobility. Surface pumps can be installed on any level ground, and the main condition for their operation is the presence of a nearby power supply (if the pump is equipped with an electric motor).
Great power. Surface pumps have the ability to pump dirty water vertically, lifting it from a depth of up to 10 m, and in the horizontal direction, such devices can move water several tens of meters.
The wear of parts of a surface-type drainage pump will be minimal, since the product is not operated in aggressive environmental conditions.
The surface pump can be installed in any room if there is a flat surface. You can work with such a device in the garage, and in the basement, and in the house, and in the cellar.

Photo No. 4 shows a surface drainage pump installed directly on the grass, which indicates its mobility.

Most models of surface pumps can work continuously for a long period of time.
If we compare the cost of surface pumping units with the price of deep, submersible and semi-submersible pumps, then it will be significantly lower.

The main disadvantages of a surface pump include the following characteristics:

Inability to operate in deep tanks and wells. These pumps must not be submerged in water.
The surface pump heats up very quickly, and in the absence of a high-quality cooling system in it, one can only count on a short operation of the structure.
This type of pumping structures is poorly protected from external weather influences. If a negative temperature is set outside, then it is impossible to work with a surface drainage pump.
Surface type pumps often operate with high noise levels. This happens due to the special design of the engine.
Suction pipes and hoses of surface pumps must be connected correctly. It will not be possible for inexperienced craftsmen to do this without the help of a specialist. Incorrect installation of the suction pipe will invariably lead to inefficient use of the pump or its rapid failure due to a tightened or torn flexible hose.

The main advantages of a submersible drainage pump is the ability of this device to pump water from great depths (up to 50 m). it can be installed in wells of great depth and wells. Another advantage of the design is the compact size, as well as the tightness of the case. The device is easy to operate and its motor runs almost silently.

Other advantages of a submersible drainage pump include:

The presence of an impact-resistant, corrosion-resistant and well-insulated case, which will be immersed in a pond or tank with dirty water.
The submersible type pump does not require cooling, and the removal of excess heat is carried out during the pumping of cold water.
The risk of freezing of the device in the cold season is minimized.
The submersible pump works silently.
The pressure of the water column is very high, which allows pumping water from very great depths.

The main disadvantage of a submersible drainage pump is the same sealed housing. Yes, of course, it reliably protects the internal contents of the product, but in the event of any breakdowns, repairs will not work, you will have to change the unit to a new one. In addition, a submersible-type drainage pump is categorically not recommended for draining shallow water bodies.

Such a unit works correctly only when completely immersed in water, and therefore it will not help to pump out all the water from shallow reservoirs. During its operation, you should constantly monitor the water level, and if this does not work out, the device will fail, burn out. Among other disadvantages of a submersible pump for pumping dirty water are:

Difficulties in preparing for work. The first step is to properly immerse the pump in the reservoir, and then set up the float automatics.
If drainage work is carried out constantly in one place, it becomes necessary to install a special design, with metal guides. With their help, the device is lowered down onto the stationary type intake flange.
The device is subject to special requirements regarding electrical safety. The insulation of electrical cables must be intact.

Types of drainage pumps

Most of the drainage pumps for dirty water are made according to two schemes: surface and submersible. Each of these schemes has its own characteristics, advantages and disadvantages. How the drainage pump works is well shown in the following video:

Photo No. 6 shows a range of drainage pumps from various manufacturers.

Surface

Surface pumps - in them, the pumping unit and the power engine are installed on a dry surface above ground level, not far from the place where the water will be taken from. sometimes the device of a surface pump is carried out on a special float raft.

The advantages of this type of pump are, first of all, in its mobility and ease of operation. Readers can learn more about the types of drainage pumps from the following video:

The liquid is pumped by such a device through a special sleeve, lowered directly into a reservoir or a special tank filled with dirty water. Such a device can be easily transferred from one place to another, but it will only work if there is a power source. However, today there is a better option. It consists in the use of ground-type pumping units operating on diesel fuel.

Photo #7 shows a surface type drain pump installed to remove dirty water.

Submersible

The operation of a submersible drainage pump is somewhat different than a surface one. It is completely placed in the water, which should be pumped out. The submersible unit is capable of pumping out too dirty water, in which there are solid inclusions with a diameter of up to 5 cm. The mechanism is equipped with a large working chamber, and due to this, all debris, together with the liquid, passes unhindered outside without clogging the unit.

Photo No. 8 shows a submersible type drainage sediment for dirty water.

The submersible pump for pumping water is divided into subspecies, namely, industrial and domestic. Naturally, if you need to pump out water in a small summer cottage, then you should not give preference to an industrial drainage pump. Such a device operates at high power, which leads to its high performance.

Of course, a device of low power and productivity will also cope with a small volume of water, so it is better not to give too much price for an industrial unit. In addition, you will have to overpay not only for the device itself, but also for the consumed electricity, which an industrial pump consumes in much larger quantities than a household unit that works with small volumes of water.

Photo No. 9 demonstrates the process of installing a submersible drainage pump.

Help in choosing

Before you buy a drainage pump for pumping water, you should carefully study its characteristics, as well as read the recommendations of experts on the choice of such devices. We present to the readers the main of these recommendations.

Purpose of the device. If you decide to buy a drainage pump, you should understand that, regardless of its model, it is intended for pumping dirty water from collectors, tanks, basements, etc. at the same time, each of the pump models has its own characteristics and features.
Pump type. Units for pumping water can belong to the surface or submersible type. Which one to choose, everyone decides individually, focusing on the features of further operation. The surface pump is mounted in the immediate vicinity of the reservoir, and only the suction hose is immersed in water from it. A surface pump is used only for short-term operation, it is capable of pumping only not too polluted water from a depth of no more than 5 m. At the same time, in the cold winter period, the operation of surface-type drainage pumps is very difficult. If you need a unit for pumping water from great depths, then the best option would be to buy a submersible pump. It will not only help to pump water from great depths, but will be able to work efficiently with liquids containing solid fractions of various sizes.
Features of the installation of automation. In front of the pump blades (called the impeller), a protective mesh must be located. It is good if the drainage pump is also equipped with overheating protection and an automatic shutdown function in case of a drop in water level.

In order to choose the right drainage pump for removing dirty water, you should know the principles of operation of such mechanisms, as well as their constituent parts. Photo No. 10 shows a detailed device for a drainage pump.

performance of the pumping unit. In order to choose the right drainage pump, some calculation work should be done in advance. Builders advise when making calculations to make a margin of about 25-30%. You should also pay attention to how exactly the suction pipe is located. If it is at the bottom, then all the water will be pumped from the tank using such a pump, and even along with dirt and solid particles. If the branch pipe is located at the top of the pump housing, then the water from the tank will not be pumped out completely, some of it will still remain in the tank. For example, using a drain pump with a top suction nozzle will not completely pump out all the water from the drain well.

How to properly use and maintain

The operation and maintenance of drainage pumps for pumping water depends on which type a particular unit belongs to. For example, a surface pump must never be completely immersed in water, since the device is only adapted to work on land. Also, surface pumping units are not recommended for pumping clean water. details about drainage pumps for pumping dirty water are described in the following video:

Manufacturers create such devices only for pumping dirty liquids, making the suction holes wide enough and thereby orienting them to the presence of small solid particles in the water.

In Photo No. 11, you can see how the drainage pump is immersed in dirty water.

There are several important rules in accordance with which the drainage pump should be operated.

If the pump for pumping water belongs to the surface type, then special attention should be paid to its correct connection to the electrical network. It is better to do this with the help of an automatic device that differentiates the supply of electricity and thereby protects the unit from burnout, possible failure as a result of a sudden power surge.
If solid inclusions of large diameter (more than 5 cm) are present in the water, then it is better not to pump it out with a surface pump. A submersible type pump unit should be selected for this purpose.
If there is a need to pump out aggressive liquids, solvents, gasoline, kerosene, flammable liquids, oily and caustic compounds, petroleum products, then a surface pump is not suitable for such purposes.
You should not give preference to a surface-type pump even if you need to pump out liquids containing insoluble particles (for example, tree branches, metal or plastic debris, other solid debris). If this requirement is not taken into account, then the surface pump will quickly fail.
It is impossible to move the pump from place to place, transport it, tilt it or shake it while pumping water.
If the outside air temperature drops below 0 ºC, then the surface pump cannot be used. So that the water pumping system does not freeze, it should either be placed in a closed and warm room, or well insulated.

Prices

Dirty water pump prices may vary depending on the brand, country of manufacture, brand awareness. Note that most of the models of drainage pumps used for pumping dirty water belong to the middle price category.

Sometimes the prices for such units may differ depending on the region of their implementation. The difference in price is, on average, 1500-2000 rubles. Here are some examples of prices for drainage pumps from different manufacturers.

Aiken is a Chinese manufacturer of a drainage pump that sets the price of its product at 2950 rubles.
Grunfos Unilift is a surface pump for pumping dirty water of class CC 5 A1 at a cost of 7400 rubles.
Grunfos Unilift is a surface pump for pumping dirty water class AP 12 manufactured in Denmark. Its cost is 17350 rubles.

It can create a pressure up to 11 m, it is equipped with an electric cord about 10 m long, capable of increasing 2.5 and even 4 times using standard connectors. You can buy a drainage pump of the Gileks model at a cost of 4990 rubles.

Photo number 12 shows several models of drainage pumps for dirty water. The price of each of them differs depending on the functions performed, power and other important performance characteristics.

And wells serve to supply water with a small amount of foreign inclusions. For irrigation from a natural reservoir, buildup of flooded basements and sewers, a dirty water pump is required. Such devices have a special design or protection of the working body from abrasive wear - an installed filter on the intake pipe.

Types of devices for moving drains and drains

Pumps are selected depending on the nature of the suspension and particle size. All types of pumps are divided into surface, submersible and universal.

All pumps for pumping muddy and dirty water are called drainage pumps. Devices can be submersible and surface. They are also called mud pumps.

But if a mud pump pumps a liquid that looks more like porridge, it is called a slurry pump. If the pump is equipped with a grinder, it is called fecal.

The buildup of a liquid with an increased amount of suspension is carried out by different devices:

cleaning of bottom sediments of wells and wells, drainage of silted chambers is carried out by vibration or screw pumps;
pumping water from ponds, pools, after flooding basements, you can use drainage pumps for dirty water;
liquid with a large number of different fractions is pumped by slurry and fecal pumps.

Use of garden pumps

Most often, summer residents have to use equipment for watering plants. In the presence of an open reservoir, water is taken by a surface pump for dirty water. Typically, low power centrifugal pumps with one impeller are used. Such a device is capable of pumping muddy water containing a suspension of no more than 1 cm in cross section.

The pump can be installed on a platform and lowered onto the water surface. At the same time, the lifting height cannot exceed 5 m, and the working time is limited and is associated with the risk of engine overheating. The advantage of the device is only in simple maintenance and low price of the pump for dirty water.

The disadvantages of a surface pump are many:

noisy work;
short service life;
a canopy is required from accidental ingress of water;
it is impossible to pump water at sub-zero air temperatures;
the device in the plastic case quickly fails.

However, for summer use in the country, surface pumps are often installed.

Using submersible pumps for dirty water

The use of devices with a sealed housing allows you to raise more turbid water from a depth exceeding 5 meters. Pebbles up to 5 cm in diameter will slip through the chamber. Water cooling increases the time the pump runs without overheating.

Pumps with a lower water intake can completely drain the tank. At the same time, the built-in thermal protection will save the engine from overheating. But such pumps do not work, plunging into bottom sediments.

If a pump for dirty water with an upper intake, a “dry run” shutdown system with a float switch, thermal protection of the electromagnet winding is selected, the buildup is carried out automatically. A vibratory submersible pump is often used to clean the bottom of wells, build pools and ponds.

Optimally, after running for 2 hours, stop the pump for 20 minutes.

If the submersible pump for dirty water is equipped with a grinder, then it belongs to the fecal class. Such pumps can swing, installed in VOCs. , installed in a muddy pond, will supply organic fertilizer in the form of bottom biological mass for irrigation. Such a pump will work on muddy water. It is he who is considered a universal device.

Advantages of the universal pump:

power;
strength;
long service life.

When choosing a pump for dirty water, only the high cost of a fecal can be an obstacle. So drainage costs 2 times cheaper than Dzhileks Fekalnik.

The most commonly used single-channel centrifugal pump. At enterprises, screw pumps are used to supply sludge to storage tanks. To lift silt deposits from the bottom of the well, a vibration pump with a lower intake is lowered. In each case, choose the most suitable system.

Varieties of slurry pumps

When draining the pit, a submersible slurry pump is used, capable of lifting stones 12-15 cm mixed with wet soil. In such devices, a particularly durable single-channel wheel and a stirrer with cutting edges are used. Preliminary loosening of bottom sediments, passing them through the filter mesh is the task of an additional unit.

Classification of mud pumps according to the nature of the extraction

So, how do you choose the most suitable equipment for your specific application? It is important that the working chamber is not clogged with waste. We classify equipment according to the ability to pump large fractions:

submersible pump no more than 35 mm;
the drainage apparatus will cope with stones up to 50 mm;
the fecal pump will pass a fraction up to 80 mm;
the slurry pump will pump over stones of 145 mm.

Based on the working conditions, from the named categories, it is necessary to select pumps for dirty water according to pressure, power and performance.

Examples of various drainage pumps

Gnome submersible pumps are a centrifugal unit with a squirrel-cage asynchronous motor. They can swing a suspension up to 10% with particles up to 5 mm. There are 50 pump models available:

household;
for public utilities;
for irrigation and drainage systems.

Patriot F 400 pumps manufactured in China under license from the USA are of low cost, they lift mud up to 35 mm, from a depth of up to 5 meters. A small device weighs 5 kg and costs about 3 thousand rubles.

About 10 thousand rubles is a submersible pump for dirty water from a well-known manufacturer Grundfos. Full process automation. But the size of the inclusions should not exceed 10 mm. Productivity of the device is 12 m3/hour, extraction from depth to 10 m.

From a variety of pumps, it is necessary to choose an apparatus that provides pumping under certain conditions.

Owners of private households are faced with the accumulation of polluted water. If it is necessary to pump out polluted or waste water in private houses or summer cottages, specialized mechanisms are used. Such mechanisms are called drainage pumps.

They are also used in construction for pumping water from pits, etc.

Variety of mud pumps

Pumps for pumping dirty water are of two types:

submersible units;
surface units.

Submersible

The submersible pump is immersed in contaminated liquid during operation. It features a wide working chamber and a mechanism that is resistant to dirt particles of various origins. Submersible pumps have the following advantages:

Quiet operation during operation
resistant to negative temperatures;
pumping liquid from a depth to a great height;
cooling occurs due to the working fluid.

The disadvantages include the need to adjust the float switch.

Surface

Are operated, being near the pumped-out liquid. Only the suction hose is immersed.

Advantages of surface-type units:

ease of use;
mobility;
budget cost;
fast installation;
low wear parts;
installed on a flat surface.

Flaws:

no cooling system. For cooling, the device is turned off;
operation at positive temperature;
noise;
poor performance.

Surface apparatus cannot cope with liquids in which there is an admixture of solid particles larger than ten millimeters. They pump out water from a depth of up to five meters.

Used for pumping groundwater from basements, emptying tanks, pools.

Surface mechanisms are divided into the following modifications:

centrifugal. There are single-stage and;
vortex. Pumping out clean liquid;
water ring. Cope with air masses in liquid;
self-priming. Are intended for pumping of sand and pure liquid;
self-priming portable mechanisms. Separate air from water. Compact devices with low weight.

By injection type:

vibration mechanisms;
centrifugal devices.

Most often, pumping occurs with centrifugal devices.

Impeller shape:

open impeller. Apparatuses of this type cope with thick masses and contaminated liquid;
single wheel. Devices of this type pump out viscous liquids. Used as a pump for pumping sludge;
rotary wheel, shifted back. productive model. Minus - energy consumption and high cost.

The principle of operation of the pump for pumping dirty water

Dirty water pumps differ in their ability to cope with impurities up to fifty millimeters in size. Particles are sandy, silty or stone.

The design for pumping out contaminated water consists of two parts:

power plant;
working chamber.

The electric motor with the help of a shaft transmits torque to the impeller. The impeller throws the liquid against the outer wall of the chamber. At this point, a high pressure is formed at the outlet of the pipe. A check valve is installed to prevent the return of liquid. The vacuum at the inlet pipe is formed due to the high pressure at the outlet of the pipe. Due to the rarefaction, the liquid rises into the chamber.

To protect the device from silt and sand of large sizes, a filter is installed.

What is the best dirty water pump?

Before purchasing an apparatus, you need to know how dirty water is and what size particles are in it. There is a list of recommendations for this.

Selection Tips:

appointment. When choosing a model, take into account what viscosity the device will work with. Each model has its own characteristics;
pump and its features. It is better to choose models that have overheating protection, automatic shutdown when a certain water level is reached and a filter;
type of pump. Depending on the capabilities, requirements for the device, submersible or surface types of devices are selected. Each of the types has its own characteristics (given above);
manufacturer. When choosing, it is worth considering the rating of the manufacturer and model. By studying the reviews on models and manufacturers, it is easier to decide on the choice of a reliable device. It is better to choose devices that have proven themselves from the best side and have a well-known name;
performance. Before buying, calculate the required performance of the device.

Operating rules

In order for the submersible pumps for dirty water to work properly, it is necessary to adhere to the operating rules. The rules vary depending on the type of mechanism. The surface pump for dirty water is placed on land.

Operating rules:

surface devices are connected to electricity through a differentiator. This event will prevent the motor from burning out in the event of a power surge;
surface aggregates when working with a solid mud admixture quickly break down. For such purposes, submersible drainage mechanisms for water are used;
submersible pumps cope well with impurities of pollution with a diameter of more than five centimeters. Superficial - up to five centimeters. This is taken into account when operating devices in different conditions;
during operation, the electric pump must be at rest, it should not be moved or lifted;
at negative temperatures, a surface drainage pump located on an open area of \u200b\u200bthe ground is prohibited to use. When working, the unit is in a closed room or is insulated;

By following the operating rules, a manual or electric household pump will last up to ten years.
