Hand pumps pumping water from a well. Which submersible pump for a well is better: criteria and recommendations on how to choose the right submersible pump. Types of drainage pumps

Drainage pumps for pumping water from a well and tanks of any other type are devices that can successfully cope with pumping liquid media, which contain a small amount of insoluble inclusions. Ordinary hydraulic machines, if used to solve such a problem, can quickly fail, since their elements internal structure very sensitive to contaminated liquid media. Various types drainage pumps for pumping water presented on modern market, differ from each other both in design and technical specifications which should be taken into account when choosing such equipment.

Application area

For country houses and dachas drainage pumps are indispensable. Using such a device, you can pump out well water from an underground reservoir before cleaning it, organize the supply of water for irrigation from natural reservoirs or storage tanks, and solve many other problems.

Before installing such a pump, it is necessary to make sure that the liquid for which it is planned to be used meets the requirements for the size of insoluble inclusions contained in its composition.

The need to use drainage pumps arises in the following situations:

• level up ground water, which leads to excessive filling of wells and sewage tanks, the appearance of water in the basements and cellars of houses;
• liquidation of the consequences of the last flood;
• liquidation of the consequences of a pipeline break;
• tidying up the local area after heavy rainfall;
• water supply to fountains, maintenance artificial reservoirs and pools;
• water supply to systems drip irrigation plants growing over large areas.

Main varieties

On the different kinds drainage pumping equipment for pumping water is divided depending on a number of parameters. One of these parameters is the installation location, depending on which they distinguish:

• submersible drainage pumps for wells;
• pumping devices surface type.

Submersible-type drainage pumps are located in the thickness of the pumped liquid medium, where they are lowered with the help of cables to a certain depth (50–100 cm from the bottom of the storage tank). Most significant virtues of these hydraulic machines are:

• compact dimensions and low weight when compared with surface pumps;
• high reliability and ability to work for a long time without special maintenance;
• a wide range of possibilities (a submersible drainage pump for a well performs effective pumping of both slightly and heavily contaminated liquid media);
• sufficiently high productivity, the value of which can reach up to 40 m 3 / hour;
• the possibility of using in automatic mode, which is achieved by means of a float-type sensor;
• ease of operation, maintenance and repair.

If we talk about the shortcomings of submersible drainage pumps for pumping water, then this should include:

• low value of the pressure of the liquid medium being pumped out, which is especially typical for those situations when it is pumped out from tanks of considerable depth;
• the impossibility of filtering the liquid medium in the process of pumping it out of the storage tank.

By design, submersible drainage pumps are divided into centrifugal and vibration. The former are characterized by higher performance, but are also more expensive than vibration pumping devices for pumping water.

Submersible centrifugal pump "Caliber"

A surface drainage pump for a well or other reservoir, as its name implies, is installed on the surface of the earth - on a specially prepared site. When using these pumps, a hose (or pipe) is used to pump out the liquid medium from the storage tank, which is connected to the suction pipe of the device. Among the advantages of surface drainage pumps are:

• the ability to create a good pressure of the pumped liquid medium (this allows it to be transported through a horizontal pipeline over a considerable distance);
• long service life (since pumps of this type are operated in more comfortable than submersible devices, conditions);
• more affordable cost when compared with the price of submersible pumps;
• low power consumption, which makes the use of such equipment economically more profitable.

Like any other technical devices, surface drainage pumps also have disadvantages:

• Hydraulic machines are used for pumping liquid medium from underground reservoirs, the depth of which does not exceed 8 meters.
• In the process of operation, surface drainage pumps make quite a lot of noise.

How to choose

Before proceeding with the selection of a drainage pump model, it is necessary to determine the parameters of the underground reservoir for which it is planned to use such a device:

• the depth of the well (it can be found using a cord with a load attached to its end);
• the parameters of the cross-section of the well shaft - the diameter or size of the sides of the shaft, if it has a square shape.

Knowing such parameters, it is possible to calculate the maximum volume of water to be pumped out. To make such calculations more accurate, it is necessary to take into account at what level in the well shaft the water mirror is located.

Design features of pumps for clean and dirty water

Qualitative characteristics of water in the well - another important parameter, which should be considered when choosing a drainage pump. In this case, such a parameter refers to both the number of insoluble inclusions in the composition of water and their linear dimensions. The instructions for each model of the drainage pump necessarily contain information on the size of solid particles in the composition of the pumped water, with which such a device can work. Naturally, in order for the pump you have chosen to work correctly and not fail after a short operation, the dimensions of the inclusions contained in the pumped water should not exceed the standard values ​​for a particular model.

The choice of a drainage pump is also influenced by the mode in which such equipment will be used - year-round, seasonal or periodic.

More high requirements are presented for the selection and use of drainage pumps that are operated year-round. Installation of such pumps is carried out in a heated room to avoid freezing of liquid in the pipeline system during the cold season.

For a more accurate selection of a drainage pump, it is necessary to determine and take into account the following parameters:

• minimum and maximum water level in the well;
• the average value of the water level in the serviced well;
• the intensity with which water arrives at the well (source debit).

Main characteristics and rules for their calculation

In addition to the parameters of the well, before choosing a drainage pump, it is necessary to determine the characteristics of the device itself. This includes the performance of the pump and the force of pressure of the liquid that such equipment pumps.

The performance of the pump, which characterizes the volume of liquid pumped by it per unit of time, is determined based on the total volume of water in the well and the length of time during which all the liquid contained in the underground reservoir must be pumped out.

To determine the magnitude of the pressure of the liquid, the depth of the water intake and the distance over which the pumped water must be transported along the horizontal section of the system are summed up.

Design features

The suction hole of the submersible drainage pump is located at the bottom of the device, which ensures the most complete pumping of water from the well shaft. For the manufacture of the body of the hydraulic machine, cast iron can be used, polymer material or steel alloy. More preferred are devices with a steel case, which is not too heavy and high strength. Cast iron cases, while robust, are heavy, and plastic ones are not strong enough.

The size of inclusions in the composition of the pumped water, which the pump can handle without compromising its technical condition, is mainly influenced by the size of its working chamber.

Installation order

The installation of a drainage pump, on the correct implementation of which the correctness of its operation depends, is carried out according to the following algorithm:

• The suction pipe is connected to a pressure hose or pipe.
• Installed in the well float sensor, which will automatically turn on the pump when the water level rises and turn it off when all excess water is pumped out.
• If the pump is connected to three-phase network power supply, you must check that the drive motor shaft rotates clockwise.

Often, residents of private houses are faced with the problem of quickly draining wastewater into a septic tank. In most cases, water leaves on its own due to the angle of the sewer pipe. In all other situations, you will need to use a pump to pump water from the basement.

Classification of household pumps

Household pumps available on the modern market are divided into the following types:

• • Drainage unit - this device is not capable of pumping out solid waste that may be in the water. To protect the small elements of the unit, the lower section of its pipe is equipped with metal mesh with small cells. It prevents large solid fractions from entering the unit. This type of equipment is used for domestic purposes.

• Fecal pump - this unit is not equipped with a filter. Because of this, he can pump out waste water and soft waste found in it. For better work such equipment is equipped with a cutting element that shreds paper and other debris in the water. These screw pumps are more powerful and are often used in factories or commercial buildings.

Both types of equipment operate on the same principle. Their function is to quickly pump out the processed liquid from the floor dry.

According to the method of working in a liquid medium, pumps of the following types can be found on sale:

• Submersible unit - such a self-priming pump for dirty water is completely immersed under the thickness of the liquid;
• External pump - only the lower part of the equipment is immersed in water, while the upper one, at the same time, is located outside. Only the part that is in the water is responsible for pumping water.

Modern units of the second type often go on sale with a built-in float. It helps to keep the equipment afloat in case of fluctuations in the level of processed liquid.

Which pump to pump water out of the basement - types and features

Among the devices suitable for pumping water from the cellar, equipment of the following types stands out:

• • Drainage pump for pumping water is dirty - such a unit is often used in private homes. Such equipment is capable of lifting water from any source. This electric pump handles very well dirty water. Due to the parts coated with an anti-rust agent, such pumps can last a long time. long time;
  • Submersible pump for pumping water from the basement - this unit allows you to quickly and easily pump out enough a large number of water. Its design also includes elements that are resistant to impact. chemical substances. This protects the unit from chlorine, alkali and various acids, with which wastewater is so "rich";
  • Semi submersible pump for pumping water from the floor dry - when working, only part of such equipment is immersed in the water column. The rest is on the surface due to the presence of a float element on which the motor is located. Units of this kind are not distinguished by high performance and power. However, such a device is well suited for pumping water from a shallow pit. There are no crushing elements in the device, therefore, such an aggregate is not capable of pumping out large waste;

• Surface pumps for dirty water - these units must be installed in places that are reliably protected from frost and high humidity. In this case, the room should be located near the basement. Such pumps for pumping water from the pit have low power and have modest dimensions. They are equipped with crushing elements for grinding small and medium-sized waste.

Everyone Vacuum pump of the listed units will be indispensable assistant at the cottage or in a private house.

Due to the mobility of most modern models, their owners can use one household pump to two houses, transporting it in the trunk of a car.

Because of large selection models pumping equipment, for beginners it is often quite difficult to decide on the option that suits them. For such cases, we have prepared our review of the highest quality pumps. Today's market leaders include:

• • Grundfos Sololift - This pump for pumping water from the basement can be installed in different parts residential building. This will help if plumbing fixtures in the house are located below the place where the processed liquids drain. This unit can be manual, electric or gasoline. In any case, the device will help to quickly get rid of sewage and tidy up the flooded basement;
  • Pump for pumping water Pedrollo Vortex - this mini unit is made of technical polymers and operates in automatic mode. It is virtually silent in operation and can be equipped with a gasoline or electric motor. In any case, it gives out a strong pressure at a depth of up to 7 meters, when a liquid is supplied, with a volume of 180 liters per minute;

• The Makita PF 1010 pump is one of the most powerful units available on the market today. This pumping device is characterized by high performance and small size. In addition, this household pump is able to pump out small particulate matter, with a diameter of not more than 3.5 cm;
• Domestic Gileks units - each drying unit of this manufacturer is distinguished by its modest dimensions and low power consumption. At the same time, the units have relatively high power and low cost.

5. Guarantor ND, Guarantor Comfort. These devices are manufactured in Russia. Have productivity up to 25 l/min. Head from 6 to 17 m. Their head is quite low, but if you do not plan to use this equipment often, then it will be enough for you.

It is good to have a house in the village or a cottage outside the city, where you can have a good rest in nature, enjoy the surrounding landscape and walks in the nearest forest. But in addition to rest and amazing relaxation, Vacation home and the structures adjacent to it, forming the adjoining complex, require attention, constant care and preventive maintenance. If you want to decorate the site, then you will probably like it. As for the technical part, one of the types maintenance work, on which the arrangement of life in the country or in the garden largely depends - this is the cleaning of wells.

hosts country houses and private houses often face this problem quite often and are forced to solve the problems of dirty water drainage on their own. After the end of winter, when the rise in temperature calls for snowmelt and in most cases the flood is so massive that it floods houses and detached basements, only a few call for public utilities, since the level of pumping costs is quite high. This will help the pump for pumping dirty water from the well.

An indispensable household assistant

You can’t scoop out a lot of water with a tool familiar to our compatriot - a bucket either. Usually during this period, the water rises so quickly that it is very difficult to cope with it. Today, the industry produces a huge range of auxiliary devices to remove dirty water:

Systems for pumping clean water are not always able to fulfill the tasks assigned to them for technical parameters. Today's electrical manufacturers offer pumps that are tailored specifically to the narrow task of cleaning wells.

Which are suitable

The modern range of pumping equipment includes the following proposals:

Especially common in small garden plots manual pump pumps (manual pump) are used. you can read more about for the well. They are characterized by energy independence, high comfort and the possibility of convenient transportation both within the garden or adjoining plot, as well as over long distances. Do not be embarrassed about the not too aesthetic appearance of this pump. It allows you to solve many problems of cleaning garden and rural house wells.

Manufacturers and prices

To dwell on a specific model, you need to familiarize yourself with the main brands, manufacturers and prices that determine the category of the unit.

Concerning pumping stations for wells, you can see the prices for them. An assortment of pumps for pumping large volumes Dirty well water is an exceptionally versatile choice for a wide variety of water supply cleaning tasks. Before choosing a model, it is imperative to consult with experts in the field of pumping technology and its application. If you are equipping a well on the site, then you may be interested in. You can also make a well instead of a well. you can read which is better: a well or a well.

Despite the fact that we live in the 21st century, in the era of technological development, many owners of private houses are still faced with the need to independently pump out dirty water. For example, if there is a need to pump liquid from basements after floods, self-priming pumps are great option problem solving.

In this article, we will tell you how to choose and what to look for when buying a pump for pumping contaminated water from a well.

1 Features of work

In devices that pump clean water, the filtration mechanism is not designed to contain solid elements. As a result, the units are often clogged with debris, which can eventually become unusable.

As for a device such as drainage or surface pump for dirty water, everything is carefully thought out here. The filtration mechanism is designed in such a way that solid elements up to 5 cm in size pass through it without problems.

But here it all depends specifically on the model - in some devices, the indicator bandwidth may be increased or decreased. If necessary, you can even find self-priming pumps for pumping water with sand.

Separately, fecal devices should be distinguished - they are designed specifically for pumping excrement from outdoor toilets. Without exception, all pumps for pumping dirty water are divided into two types - submersible and surface.

1.1 Surface pumps in detail

The surface pump for dirty water from Leroy, Merlin, Sterwins or from another manufacturer is a device designed for pumping slightly contaminated liquid. As a rule, such self-priming units are designed to work with particles of no more than 1 cm. As the reviews show, they are usually installed near the fence on a hard surface, and the pipe is lowered into the reservoir.

Since such vibration pump characterized by low power and positive reviews, it is important to buy it if it will not be used constantly. For example, if you need to water the garden several times a month or pump water out of the basement a couple of times a year.

At constant use Leroy, Merlin, Sterwins or from other manufacturers, as reviews show, fail more often. It must also be taken into account that such devices are not designed for wells and great depths.

Most optimal depth for such a pump, as consumer reviews show, is 5 meters. As for the body itself, it goes without saying that plastic options are cheaper, but they are less reliable than metal ones.

1. The advantages of such devices include ease of installation and use. The unit can be mounted almost anywhere, as long as there is an outlet nearby.
2. The main disadvantage is the inability to operate the unit when sub-zero temperature. As reviews show, if it is necessary to pump out water in winter, devices often freeze, respectively, over time this can cause failure.

1.2 Choosing a submersible pump

2.1 How much does it cost?

The cost of the pump directly depends on its quality and manufacturer. In the domestic market, you can find pumps with a very large price range. For example, if you choose a surface installation with a capacity of 0.75 kW, then its average cost will vary from 4 to 10 thousand Russian rubles(from 1,700 to 3,500 hryvnias).

More quality products from European manufacturers, for example, from Germany, Hungary, France or Denmark, respectively, has a higher cost. Relatively inexpensive pumps are made in China.

The question of quality in this case remains open. Despite the fact that China has been producing low quality products for a long time, Over the past few years, the market has increasingly seen both inexpensive and high-quality goods at the same time.

It all depends on the case - how lucky you are, but usually Chinese products work no worse than domestic ones. If you plan to use the pump for a long time, then it is better to choose a higher quality option.
