The pump for pumping out of fecal and household waste. Do-it-yourself sewer pumps. Types of pumps by installation method at home

Assumes regular cleaning. If this procedure is not performed on time, then the site will worsen sanitary conditions, or the cesspool will be overflowing. And then it will be even more difficult to care for individual sewers. To pump out sewage quickly and efficiently, the called sewage truck, equipped with the appropriate equipment, will help you. The main element involved in the pumping process is Vacuum pump for sewerage. With it, the machine will clean your drain facility in just a matter of minutes.

The sewage vacuum pump is designed to work in conjunction with other equipment installed on the sewer truck. With its help, the contents are pumped into a special tank, in which it is taken to the place of disposal. The working principle of a vacuum pump is creating a vacuum in the working chamber in a short period of time. As soon as this rarefaction reaches the required value, the pumped out substance (sewage, sewage, steam) is sent to the storage tank. This type of pump is considered the most efficient in operation and safe for the environment.

What is a waste machine

Since we are considering pumps installed on silt pumping machines, we will explain what a sewer machine is for pumping sewage. This is a set of wheeled equipment that pumps out sewage or sewage from tanks, septic tanks, settling tanks. After pumping out, the machine delivers the contents to the places of its disposal, where it unloads sewage.

A typical sewer machine consists of the following main elements:

• storage tank. This is a steel cylindrical tank with a slight slope for easy unloading;
• Vacuum pump;
• safety signaling device. Its presence prevents the tank from overflowing and signals the operator;
• intake hatch with suction hose;
• pipeline control valve;
• additional electrical equipment.

Vacuum sewer pumping machine works according to the following principle. All equipment is powered by a running engine. The suction hose is immersed in the container with the pumped out contents. The vacuum pump is switched on, creating a vacuum in the tank. The cistern is filled with sewage. After it is completely filled, it works safety device turning off the engine. After arriving at the place of unloading, the tank is emptied by gravity or by air pressure in the pump.

Tip: When calling a sewage truck to your site, ensure that it can freely travel to the pumping point.

Types of vacuum pumps

• a high vacuum pump will be useful when working with low pressures. As a rule, 2 pumps connected in series are used;
• a low vacuum pump lowers the pressure of the pumped effluents. Also, the device creates pressure inherent in low vacuum;
• foreline pump is used to obtain in the system high level rarefaction. It provides the conditions for the pump to operate at a higher vacuum level. The pump saves energy;
• the booster pump creates a medium vacuum in the system. It is usually installed between the foreline pump and its high-vacuum counterpart;
• a pre-vacuum pump can be used to reduce the pressure of the contents from atmospheric level to a pressure that another vacuum pump would normally operate at.

Main characteristics of pumps

Parameters characterizing the work specific model vacuum pump for sewage pumping:

• pumping speed. This is the amount of content to be pumped out per unit of time. It is determined in the inlet section of the receiving pipeline;
• maximum starting pressure. This parameter characterizes the maximum inlet pressure at which pumping will begin;
• outlet pressure limit. This is an indication of the pressure at the outlet of the equipment when the pump will still be able to pump the substance at rated speed;
• the performance of the device for pumping steam. In the process of pumping out liquid, the amount of vapors is considered in weight units;
• maximum residual pressure. This is the theoretical value that is approached operating pressure under standard conditions;
• steam pressure is maximum. This is the highest steam pressure at the pump inlet. This indicator is taken into account when pumping steam;
• compression ratio of the pump. The indicator characterizes the ratio of the volume of gas compressed during its compression.

Features of operation of vacuum equipment

During the operation of vacuum equipment, it is necessary to observe certain conditions due to which the equipment will work properly for a long time:

• For the correct operation of the device, it is necessary to flush its lubrication system with new oil. Used oil must not be used;
• the pump must be kept clean. The presence of contaminants can impair its performance and even lead to damage to the device;
• it is necessary to constantly monitor the oil consumption, preventing it from reaching the minimum level. The average oil consumption is about 90 g/h;
• it is unacceptable to operate the pump without stopping for more than 1 hour;
• to determine the direction of rotation, you need to pay attention to the pump housing, where the corresponding arrow is located. Right hand torsion pumps are purchased for installation on diesel vehicles. At the same time, pumps with left-hand rotation are installed on carburetor machines.

In a house located remotely from the central sewer, the only way out will be an autonomous sewer system. What a submersible fecal pump suitable for pumping sewage: pressure, vacuum, pumping or toilet with a grinder, will we try to figure it out within the framework of this article?

If it is not possible to drain waste liquids by gravity into or into the central sewer system, best solution for forced sewage will become fecal submersible pump. This device designed specifically for pumping and subsequent transportation of dirty water that enters or into a cesspool as a result of human activity. It is designed for household needs such as drainage from bathrooms, washing and dishwashers etc.

sewerage pump

Unlike drainage, it allows you to pump out not only sewage, but also solid deposits that accumulate in cesspools. Pumping equipment of this type will provide high-quality work, have a long service life, and most importantly, it does not require special maintenance.

Submersible fecal pump: principle of operation

When designing an efficient sewer system private property, it is important not only to make calculations for the optimal location or wells, and pits, but also to correctly select a fecal pump. To date, the submersible unit is considered the best for forced sewage.

Submersible fecal pump device

Unlike surface and semi-submersible, the design of submersible pumping equipment Wastewater involves installation below the water level - at the bottom of a storage tank, septic tank or. The principle of operation of this equipment is almost the same as that of drainage equipment, but it is based on a different design, since it is designed for pumping wastewater with large diameter solid inclusions.

Since a submersible pump for pumping out sewage is constantly in contact with an aggressive environment, its main working parts and housing are usually cast iron or made of stainless steel. The device operates in full autonomous mode due to the presence of automation, as well as a float switch.

Main selection criteria

When choosing a fecal pump, you should consider:

• the planned volume of the pumped liquid;
• the depth of the future dive;
• distance from the water intake to the destination;
• pressure force;
• diameter of the main passage of the pipe through which they will be transported sewer drains into a septic tank;
• type of motor cooling;
• location of pipes.

Choose the right pump for your needs

When choosing suitable model First of all, you should pay attention to the performance of the device. The higher this indicator, respectively, the greater the speed of the device. Average value for main passage diameter sewer pipe- up to 0.8 cm. The larger the diameter, the higher will be the proportion of foreign matter present in the dirty liquid, which the pump can eventually pump.

The head pressure of the device should also be taken into account. Conventionally, 10 m is considered an average value - this value is enough to raise the liquid to a height of 10 m and then transfer it 120 m in a horizontal direction.

For uninterrupted operation the device must have a suitable power: than more people will live in the house, the higher the power should be and pumping equipment for pumping wastewater. As a rule, it reaches about 25 cubic meters. m/h, maximum power submersible pumping station- up to 40 kW, which allows pumping and pushing liquid to a height of up to 15–20 m (about 400 cubic meters per hour).

With regard to the type of cooling of the drive motor, it must be able to cope well with heavy loads in order for the pumping unit to work without overheating.

The device of the cutting elements of the fecal pump

Last but not least important aspect choice is the type of nozzle arrangement, which will directly determine future way installation. Usually, the installation comes down to the fact that a special pipe is placed at the bottom of the tank, and guides are placed on the walls in order to lower or, if necessary, raise the equipment along a cable or chain.

The process of descending to the bottom of the pit is quite simple: the pump for pumping sewage onto the pipe is easily mounted under its own weight. A vertical type branch pipe is more convenient than a horizontal one, since it is easier to screw a pipe into it from above, while an additional adapter will need to be installed to the latter.

Formula for calculating the depth of immersion

It is easy to determine the height to which the pumped wastewater should be raised using the formula G + D / 10, where:
G - immersion depth, m;
D - hose length from cesspool or septic tank to the place of liquidation of wastewater, m;
10 - dividing the value by 10, since 1 m of vertical length is equal to 10 m in a horizontal position.

Scheme: fecal pump submersion

For example, the pumping unit is lowered 6 m deep, the distance to the place where the liquid will go is 30 m. We perform the calculations: 6 + 30/10 = 9 m, therefore, for forced sewage, equipment will be required that raises the drains up to a height 9 m

Varieties according to the principle of work

Depending on the type of sewage and the presence of solid impurities in the composition of contaminated liquids, a fecal pump is selected:

• pressure;
• pumping;
• vacuum;
• toilet with grinder.

Scheme: sewer pump device

Between themselves, these varieties differ in the principle of work, allowable temperature for the discharged liquid, as well as the presence or absence of a grinder. The toilet unit with a special cutting mechanism is not afraid of blockages, it is designed to pump liquids with any solid inclusions whose diameter exceeds 3.5 cm.

The principle of operation of this type of equipment is reduced to automatic start knives that grind in seconds, and then the pump pumps the resulting liquid towards the central riser.

Attention! Pumping equipment with a grinder is equipped with special knives for solid impurities, which grind any objects, including those that got into the sewer system by negligence.

Comparison of pumping equipment for hot and cold drains

If it is intended to use country shower without heating, you can put a simple pressure or vacuum unit, while a model that is resistant to high temperatures is suitable for pumping hot drains. Equipment for pumping cold liquid waste has a temperature limit of up to 400 C.

Universal sewer pump

Some models equipped with knives are universal - they grind inclusions of a large fraction and can pump both cold and hot drains, but such equipment is expensive. Usually the unit is installed behind the toilet, with which it is connected by an adapter.

Advice! You can save a lot by carrying out a separate installation for each plumbing unit: for a bath / shower and washing machine put a vacuum or other unit that can withstand high temperature, and for the toilet - a toilet pump for cold drains with a grinder.

How the label is read

For right choice pumping equipment, it is necessary to understand the marking:

1. the presence of some digits indicates that pump equipment can be used for the removal of not heavily polluted wastewater, which contains the inclusion of solid particles up to 5 mm;
2. the designation “Ф” in the marking means that the device will cope with pumping out highly contaminated waste liquids and will pass particles with a diameter of up to 35 mm;
3. the letter "H" indicates the material of manufacture of stainless steel, which confirms the possibility of using the equipment in an aggressive environment.

To make sure that the equipment suits you, study the documentation for it.

How to extend the life of pumping equipment

For non-stop operation of the treatment plant, it is recommended to install a second sewage pump - it will serve as a safety net in case of a breakdown. For this, a so-called receiving two-section well is being built.

Scheme: device of a two-section septic tank

It is also possible to equip two wells at once, built from concrete rings and connected by an overflow pipe, where a grate will be used to retain large diameter solids. In one part of the structure, wastewater will be received, and in the second part, pumping equipment will operate.

If the site has autonomous sewerage it must be cleaned regularly. Untimely implementation of such a procedure leads to the fact that sanitary conditions begin to deteriorate at the site, the cesspool or septic tank overflows. Subsequently, it will be much more difficult to care for the sewer.

To quickly and efficiently pump out sewage, you should call a sewage truck, which is equipped with everything necessary equipment. The main element involved in the pumping process is the vacuum pump. With the help of it, the machine is able to clean the drain structure in a few minutes.

Principle of operation

The sewer vacuum pump is used to work together with other equipment that equipped with a sewer machine. With the help of it, the contents begin to be pumped into a special tank, after which it is delivered to the place of its disposal.

The principle of operation of the vacuum pump is that a vacuum is created in the working chamber in a fairly short period of time. When such a rarefaction of the required value is reached, the pumped out substance (wastewater, sewage, steam) begins to flow into the storage tank. This type of equipment is recognized as the most effective for such work.

What is a sewer machine

When considering vacuum pumps that are installed on suction machines, it is necessary to explain what a sewage machine is, used for sewerage pumping. This is a set of equipment that pumps out sewage and sewage from cesspools, septic tanks, tanks, settling tanks. After that, the machine brings the contents to special places for disposal, where it unloads sewage.

The sewer machine consists of such important elements:

• storage tank, which is a cylindrical steel tank with a slight slope, so that it is convenient to unload;
• a receiving hatch having a suction hose;
• additional electrical equipment;
• a signaling and safety device that helps prevent overfilling of the tank and signals the operator about it;
• pipeline control valve;
• Vacuum pump.

Such a sewer pumping machine works as follows. First turn on the engine. Then the suction hose is immersed in a container with the contents to be pumped out. The vacuum pump starts to work, which contributes to the creation of a vacuum in the tank. The container is gradually filled with sewage. As soon as it is completely filled, a safety device is activated that turns off the engine. After arriving at a special place, the tank is emptied by air pressure in the pump or by gravity.

Types of vacuum pumps

Main characteristics of vacuum pumps

Such a device used for pumping sewage must have the following characteristics:

Features of the operation of pumps for pumping sewage

When operating vacuum equipment, you need to adhere to certain conditions, thanks to which it will work smoothly for quite a long time.

In order for the device to work flawlessly, it is necessary to use new oil, which should flush its lubrication system. It is forbidden to use used oil for this.

The pump must always be kept clean. Available pollution significantly impairs its performance, which may cause it to break. It is necessary to monitor the oil consumption at all times in order to prevent the minimum level from being reached. The pump must not be operated without stopping for more than one hour.

To determine the direction of rotation, it is necessary to pay attention to the pump housing, where the corresponding arrow is located. Pumps with right-hand torsion are used for installation on diesel vehicles. But on carburetor cars, pumps with left-hand rotation are installed.

Types of malfunctions and their elimination

Vacuum equipment malfunctions can be as follows:

Conclusion

The use of vacuum units used for sewage pumping is essential to ensure that the sewer system is always in order. Its overflow can disrupt sanitary norms and lead to ecological disaster. Vacuum equipment is able to quickly and efficiently solve the problem of disposal of liquid household waste.

When living in a private house, there are 2 options for pumping out sewage: either you hire special services whose main task is maintenance or a septic tank, or you do it yourself. The prices for specialist services make many people stick to the second option, for which you will definitely need a sewer pump in a private house.

Differences between drainage and fecal pumps

There are 2 types of pumps for pumping contaminated water (fecal and drainage). Drainage pumps for sewage in a private house divert only those polluted waters that contain only small solids. If larger particles are also present, then, unfortunately, one cannot do without special grids.

Fecal sewer pumps in a private house will help you pump out water that contains relatively large particles. For example, drainage pumps they will definitely not cope with pumping out sludge (due to the density of the medium). Fecal pumps are also used to pump incredibly dirty liquids from septic tanks or cesspools. Maximum Width solid particles, which can be caught in a contaminated liquid, is almost 5 cm! Fecal pumps are also often equipped with a special grinder that allows waste to be pumped out before it rots.

Types of pumps for pumping sewage

Pumps can be divided into types according to two criteria:

1. By material.
2. By installation type.

Let's consider them in more detail.

By material

All pumps that are used to pump out sewage are in an aggressive environment. The pump housing must meet certain requirements. First, it must be sealed. Secondly, the materials must be resistant to various aggressive environments. For the manufacture of such pumps use:

1. Special plastic.
2. Cast iron.
3. Stainless steel.

Not all plastic can be used in the production of pumps operating in an aggressive environment. Despite this, this option is the cheapest, and the quality of such pumps is disappointing.

Fecal pump with knives

Stainless steel is the most the best way for sewage pumps, the only drawback is that it makes the pump very expensive. If you don't have the money for a stainless steel pump but want to get quality equipment, then consider cast iron installations, which are the "golden mean".

By installation type

Varieties of fecal pumps

There are three types of pumps according to the type of installation:

1. Submersible pumps. Such installations are always placed at the very bottom of the reservoir with the medium, the pumping of which is their main task. Almost all such pumps are automatic (activation occurs using a float switch). There are two options for installing such equipment, because they can be mounted both permanently and mobile. If you choose option 1, the design will turn out to be very reliable, but inaccessible, so there will definitely be problems with repair and maintenance.
   Mobile submersible pumps have no this shortcoming, they are always fixed on two rods, and a special chain is attached to the upper part, which will help you get the pump if necessary. Corrugated pipes, which are used with this method, also need regular maintenance, do not forget about them!
   And most simple option is a simple immersion of the pump for a certain time, main disadvantage is that the equipment must be constantly removed and cleaned. Such pumps do not make noise, do not heat up, pump out liquid at great depths and work automatically!
2. Semi-submersible pumps. Such designs require a special installation: the motor must remain on the surface, and the suction part must be immersed to the maximum depth. These pumps are cheaper because they don't need a complete seal for the motor, but unfortunately their power is lower than that of submersible pumps, and the depth to which the suction part goes down is frustrating. Semi-submersible pumps do not support choppers, but maximum size particles is significantly lower than standard submersible models. Such pumps are not popular.
3. Surface pumps. Surface pumps differ from other options in that only the hose is immersed in the liquid, so their performance is much lower than that of the previously presented models. Savings come from the fact that the body of surface pumps is not trimmed with special resistant materials. Such models attract ease of installation, as you just need to lower the hose into the tank. Surface pumps must not be used at great depths, because they can fail (the reason lies in the cavitation effect), the motor power is also not enough to carry out the work!

Below you can see the fecal pump in action - pumping out sewage from a cesspool.

Video Pumping a cesspool with a sewer pump

Autonomous sewerage when living outside the city in a private house is a definite plus. However, its maintenance is not without problems and hassle. The most serious of them is the periodic pumping out of a silted cesspool or septic tank. And, since it is usually expensive to call a sewer cleaning company, many homeowners are seriously considering purchasing their own domestic sewer pump in order to solve this issue as efficiently and economically as possible.

Pumps sewer type apply in the following situations:

• Removal of drains and silt from an operated septic tank.
• Withdrawal dirty waters formed as a result of flooding or flooding.
• Organization of forced pumping of sewage.
• Removal of thick deposits in autonomous sewer systems.
• Cleaning cesspools and toilets.

Due to their practicality, they are in great demand among the owners of country and private houses, as well as buildings located away from the centralized sewerage system. In addition, such a unit can be used as a sewage pump in an apartment, in situations where there is no possibility of draining wastewater by gravity.

Differences from drainage pumps

Wastewater with pollution can be pumped out using two types of pumps: sewer (fecal) and. Despite many similar characteristics, they have a number of significant differences, including:

In the photo, submersible sewage pumps with a grinder

Varieties, characteristics

Sewer type pumps are divided into several types. These include:

• Pumps without choppers, for water temperatures up to 40C⁰. They are affordable and different from pumps drainage type only with a larger width of the flow channels. Suitable for pumping ground water, which do not include a large number of lumpy particles flooding basements during the spring flood.
• Pumps without choppers, for pumping water with temperatures up to +90C⁰. They are often used to pump out the drains of baths or laundries.
• With choppers, for pumping cold drains. The most common, used for cleaning cesspools and toilets.
• Chopper pumps, pumping hot water . It is rarely used in the private sector. Designed for large bath complexes equipped with toilets.

According to the method of operation, they are divided into the following groups:

• Submersible.

They function when completely immersed in the pumped out effluents. To fix them at the bottom of the pit, guides and a corner outlet are installed.

Scheme of the submersible sewage pump Calpeda

Useful information: When purchasing a submersible sewage pump, please note that the models different manufacturers have different maximum immersion depths.

That is, if horizontal-type pumps (with an upper nozzle) can be used to operate at a depth of up to 100 m, then vertical ones (the nozzle is located on the side) can only be submerged up to 7 m.

• Semi-submersible.

They sink halfway into the sewage water: the pump part is immersed, and the engine remains on the surface. To hold the pump housing on the surface of the drains are used special devices- floats. Not suitable for pumping wastewater with fecal contamination due to the lack of a grinding device.

• Surface.

Unlike previous options, household pumps for pumping out sewage are installed outdoors in the upper part. sewer wells, and their intake hoses are lowered into the wastewater. This method of installation is called "dry".

Please note: Due to the lack of grinders in the design of pumps of this type, they are not suitable for pumping wastewater with fecal matter.

Materials used in the construction of pumps

Since the main area of ​​application of sewage pumps are environments with a rather aggressive character, increased requirements are imposed on the quality of the materials from which they are made. This is especially true for submersible pumps, all components of which are manufactured from materials with increased resistance to destruction and corrosion.

These include:

toilet pumps

• Cast iron. It has a shorter service life, but also has good wear resistance and high quality. Disadvantage: a lot of weight, complicating the process of installing the device.
• Plastic. It is an excellent example of the ratio: price + quality. Durable, lightweight, has a more aesthetic and attractive appearance. Disadvantage: not suitable for operation inside cesspools and septic tanks. It is better to use such a pump for pumping sewage in an apartment, placing it near the toilet, where it will look quite organic and will not stand out from the general situation. toilet room. More about .

Criterias of choice

Choosing a device for pumping out the sewerage of a house, apartment or suburban area, you should pay attention to several main points that have a direct impact on the efficiency and quality of this device.

These include:

• Conditions for future operation and pump performance.

For pumping water from large quantity pollution and cleaning of the domestic sewer system, it is necessary to choose pumps of the appropriate type, with an outlet diameter of at least 80 mm. Optimum performance for household pump for sewerage in a private house - from 5 to 25 m 3 of pumped liquid per hour, depending on the volume of the cesspool where it will be installed.

• Case material and accessories.

Depending on the operating conditions of the pump, the financial capabilities of the consumer and the nature of the operation, this may be stainless steel, cast iron or plastic.

• The location of the pipes.

It can be vertical and horizontal, which affects the immersion depth of the pump.

Please note: For a horizontal type branch pipe, it is necessary to use a special adapter, which is installed during the installation of the device.

• Maximum pressure.

According to technical standards the maximum head of the sewage pump is 10 m. That is, pumps of this type, when pumping, are able to lift liquid 10 m up vertically or move it 100 m horizontally. However, in actual conditions, these figures are slightly less, depending on the vertical and horizontal parts of the pipeline.

• Engine cooling.

The sewer type pump motor can be cooled in the following ways:

- by means of the liquid pumped by it;

- using oil.

Please note that oil-cooled units are more durable and reliable, as they heat up more slowly. However, the cost of such devices is quite high. That is, with infrequent use, the cost of acquiring them may not pay off.
