If you have a private house and an individual sewage system, you can either cause periodically special services to maintain septica or AU, or maintain devices yourself. Service prices such that, despite a very unpleasant procedure, people do it themselves. For such work, you need a sewage pumping pump. This is a special device that can pump very dirty water.

Drainage and fecal - what is the difference

To pump polluted water there are two types of pumps: drainage and fecal. What do they differ? Drainage are designed to drive contaminated waters containing solid inclusions of small sizes - Il, sand and other substances of approximately this size. To prevent ingestion of larger particles, mesh are installed. As you understand the description, drainage pumps It is suitable for pumping the clarified waters from the storage well, standing after septic, to pump water from a storage well of drainage and storm sewage.

If you need to pump off from the automatic individual cleansing installation (type or other), or the sediment from the bottom septicism, the drainage will not cope with it. Too dense medium. For the septicity, the exit, in principle, there is, waving a precipitate, pumping out, pour water again, shake again and pump out again. It is possible to do so, but the septic will then go to the operating mode for a very long time, so it is possible to apply this method only in extreme cases. It is better to purchase special equipment that can cope with a compressive sediment.

For cleansing cesspools and septones, fecal pumps are used for sewage. They can pump strongly contaminated fluids, viscous media in which solid particles can contain. The particle size depends on the model, but the maximum value is 50 mm. Not always in the cesspool, all waste is overloaded to such a state. In order to be able to cope with the situation at the bottom of the pump, the chopper is installed. It is usually put on centrifugal models - additional cutting blades are installed on the shaft. Already shredded in the working pump of the pump.

So if you plan to use a fecal pump to pump a cesspool, it is desirable that the shredder is present in the model. It grinds larger particles to permissible sizes.

Types of fecal pumps

Pumps for pumping sewage effluents work in an aggressive, chemically active environment. In addition, their hull should be sealed, the materials from which it is made should be chemically neutral and racks to aggressive environments. Such materials are quite a bit:

• stainless steel;
• some types of plastic;
• cast iron.

Most best Material - Stainless steel, but the same material is the most expensive. The most budget option is plastic case. These models are the cheapest. In the average price category, fecal pumps for pumping sewage with cast iron housing. Despite the fact that you have to use this device infrequently, you should not choose cheap models. Is that for giving, where you come only from time to time.

By installation Pumps for pumping feces are:

• Submersible. They are installed on the bottom of the tank, usually work in automatic mode. Turning on / off occurs using a float switch. The float rises / lowers with the level of fluid when it is downstairs, the pump is disabled.
• Semi-grade. These pumps are stretched in length, their suction part is quite far from the motor. A motor remains on the surface, it floats on a special platform, the suction part is thicker.
• Surface. Only the hose is lowered into the tank, connected to the inlet nozzle, the device itself is located next to the tank. The surface fecal pump for sewage is usually plastic case and a small performance. This is basically a country option.

Now it is necessary to understand all this manifold - when and which devices are better to use.

Features of operation and installation

When choosing a sewage pumping pump, it is necessary first of all to be based on the conditions of the equipment. If you pick up the equipment for the giving seasonal stay, there is no need to spend money on expensive and powerful submersible models. For these purposes, small and mobile surface units will be optimal. They are good because they can be converged with them for winter - weigh 5-12 kg, depending on the power. If the equipment is selected for a private house permanent residenceIt makes sense to acquire more expensive equipment that can be installed stationary.

Submersible fecal pump

This equipment can be installed inpatient or mobile. With a stationary installation on the day they make the platform to which the body is fixed. Pipes (usually plastic) are connected to the outlet nozzle. The option is not bad, but if the need for repair or maintenance - it is not clear how to get installation.

How to install a submersible fecal pump for sewage yourself

The pipe, coming from the pump, can be removed up to the surface of the Earth, and can be laid and paved, say to the accumulative tank underground pipeline. This is an option for those who have to septic / cesspool the usual assessing machine can not reach. In this case, a special car with a long hose is required. But a couple of such calls is equal to the cost of the mud pump of the average price category. Therefore, often in such cases in the available places build / establish a storage tank, in it with fecal pump Pump the remnants, and then cause the usual car.

The second, mobile version, in this regard is better. Along one of the walls of the tank, two rods are mounted. Diameter - a little less than the diameter of the holes in the case. To the top of the submersible pump for the sewage, the circuit is fixed, a corrugated pipe is connected to the outlet. Next, the hull is put on the installed rods, and how the rails are lowered to the bottom. With this method of installation, if necessary, the pump is pulled out for the chain. Minus there is only one - the need to use corrugated pipes. Their structure leads to the fact that pipes are often clogged, respectively, they must be changed, as they are very unpleasant to clean.

Installation options for sewage pumps for sewage (drainage and accumulative wells)

It is possible to avoid using a corrugated hose in models, with the lower arrangement of the suction nozzle. In this case, the rigid (plastic) pipe is assembled, the end of its output so that the pump falls on the guide to it (in the photo on the right).

And the easiest installation option: just on the chains omit the device to the bottom. When the drains are folded to the desired level, the equipment is turned off and removed from the tank, washed, dried and carved into the utility room until the next use.

Despite the rather complicated installation, the submersible fecal pumps are most popular. This is explained by the fact that they are usually more powerful, and also precisely they can pump mediums with particles up to 50 mm in size. And it is submersible models that can be with a shredder.

The advantages of submersible pumps:

• They can raise fluid from large depths.
• It can work in automatic mode, using the float controlling the fluid level.
• No need for cooling.
• Low noise levels.

It is submersible fecal pumps that can develop sufficient power to pump content from great depth. In the case of sewage, it may be not so important - not such a big depth of septic. But if necessary, you can pump drain on a large distance over the surface. The main thing is that the hoses are enough.

Semi-grade patterns of fecal pumps

This type of equipment combines the dignity of surface and submersible pumps. Since the engine is on the surface of the water, it is impossible to make it waterproofing. There is also no need to tightly combine all the details in the housing. All this has a positive effect on price - it is significantly lower than the submersible models.

The lack of fecal semi-duty pumps is a smaller particle size that it can suck, smaller depths where it can work. The disadvantage is also in that this type of pumps cannot be installed chopper. However, not all minuses are essential for domestic use. Too greater depths for private application are not needed, and a simpler design makes the repair more accessible, so that the advantages are clearly more.

One of the types of semi-tube devices - vertical

The feature of the installation of semi-duty pumps - it is necessary to install it so that the motor is over water. The installation method depends on the model, it is registered in the instructions for the product. There are several ways to install:

• Make a platform on the wall of the reservoir, equipment is fixed on it. With this method of installation, it is necessary to ensure that the fluid level does not rise above the site - the upper part of the housing is not sealed. You can control the level using automation - sensors that give a signal to turn on and off.
• Installation on a floating pillow. This method of installation is in small semi-duty fecal or drain pumps of household appointments.
• Very small models that are also called "barrels" can be hung on board.

Despite all the advantages, this model is not used so often. Basically, the sewing pump is acquired submersible or surface type.

Surface models

The simplest installation of surface-type facal sewer pumps. The device itself is put on Earth, and only hoses are lowered into the container.

The most serious lack of such models is cavitation phenomenon, which occurs when pumping fluids from large depths. Cavitation is the saturation of the reciprocal medium with air bubbles. If such a mass falls into the working organ of the pump, he fails. It is for this that it is not recommended to use surface fecal pumps at the depths of large than those for which they are intended. In the case of pumping septica or storage well, the use of such models is justified. They have a small depth, and not even the most powerful motor can cope with the task. It is only necessary to choose the correct power of the unit.

Dzhelex Jumbo 70/50 p 3701 with ejector	self-priming	1100 W.	50 M.		Non-idle protection no, maximum particle size 0.8 mm	115$

Please note that all models of surface pumps are designed to pump water. Only some of them can pump viscous fluids, and this should be indicated in the description or passport. The disadvantage of this equipment - it requires a homogeneous medium - the maximum particle size, which they are able to pump - 0.8 m. There is no doubtful price, but among submersible models there are quite inexpensive - for example - Djilex and Ebara (Ebara). The latter is so also the case has stainless steel and a wide range of different pressure and productivity.

How to calculate the required lifting height

Choosing a fecal pump for sewage to pay attention to two characteristics: its power (performance) and lifting height. With performance, everything is more or less understandable - it depends on the volumes that need to pump. The height of the lift will have to be considered, because in addition to the vertical component, with which everything is clear (this is the depth of the well / septic, with which it is necessary to raise the drains), there is another horizontal component - these drains should be transmitted somewhere, usually in some container. That distance to which it is necessary to transfer the drains in the horizontal plane to be divided by 10. The result is added to the height of the lift from the well.

For example, the depth of the well of 4 meters, it is necessary to pass the drains of 35 meters. Total we get: 4 m + 35 m / 10 \u003d 7.5 m. In specifications The pump should be the height of the lift of at least this figure, and better by 20-25% more so that the equipment does not work at the limit, which leads to premature wear. Now you know how to calculate the sewage pump.

The cesspool is the simplest sewer drive, requiring periodic emptying. In order to release the sediment capacitance, they usually cause districts.

However, the fecal pump for a cesspool pit will help with this task, which helps empty the drive independently. Let's admit: not all of us know which unit should be selected for the specified procedure.

We have reliable information that gives answers to a wide range of issues arising from the owners of autonomous sewer systems. Using the information we submitted will greatly facilitate and speed up the choice of technical device.

The article proposed to the attention of site visitors is thoroughly described. constructive features and principle of action of fecal pumps. The differences between the aggregates depending on the upcoming operational conditions are indicated. To help the buyer is given a rating of popular models, photos and video reviews.

The main purpose of the equipment is to pump out a viscous and dirty liquid with a high concentration of fibrous and solid inclusions. Mechanisms easily copble with the processing of fluid, the linear size of which can reach 50 mm.

Pumping equipment of the fecal category is intended for pumping and transporting liquids with an impressive amount of organic inclusions. In order for the pump not to be clogged, the units are equipped with a shredder

Mud pumps are indispensable:

• with sewer wells from climb deposits;
• in the transportation of wastewater with the possibility of their removal on the range regulated by sanitary norms;
• when draining the storm canvas and basements of houses.

The need for such equipment may occur during arrangement. They are installed when it is necessary to compensate for the small angle of inclination of the pipeline in order to prevent clogging system.

The main structural elements of the aggregate are:

• engine - a device that converts energy-generated energy into a mechanical work that leads to the motion of the pump;
• water pump - moving part pumping fluid into a special reservoir;
• input channel - ensures liquid to enter the pump;
• output valve - Divideces in the sedimer.
• grinding - Rotating element intended for grinding large inclusions.

The characteristic difference in fecal devices from other types of pumps is increased reliability and larger diameter of the channels.

POMP is responsible for creating a forced circulation of fluid in the system; Its malfunction can provoke a serious imbalance of the internal thermal regime of the unit

The chopper is a mandatory functional element of most models. It is the rotating knives installed at the entrance of the unit. Grinding branches, garbage and even small stones in small-sized fractions, rotating elements warn clogging and disabling the unit.

For convenience of use, some manufacturers equip submersible models with cables or sled lifts. They simplify the extraction of the unit to the surface after the completion of the work, for carrying out prevention or in the event of a breakdown.

Not always to the owners of their homes can be connected to the citywide sewage system. Therefore, most often in private houses create independent sewer systems, the maintenance of which falls on the owner's shoulders at home. In the conditions of a similar location to the city for cleaning the sump, you can always call the assessing agents. But what to do, when to the city is far enough, and every challenge costs a considerable amount of money?

In this case, the situation saves the submersible fecal pump to pump sewage at home. Which of the types of pump to choose? Press, vacuum, patching or toilet with chopper for forced sewage - Let's try to figure it out.

Pumps for sewage in a private house

The main difference of submersible pumps from drainage and semi-duty is that they are intended for pumping waters with large solid inclusions. They have it at the bottom of the cesspool or septic. The case and parts of the pump must be made of stainless steel or cast iron. Do not forget that the pump always works in a complex environment, because there should be no soft and brittle materials in it. Automation and float switch allow the pump to operate in full autonomous mode.

Basic selection criteria

When choosing a pump, you must consider several particularly important points:

• the volume of fluid that pump will pump;
• immersion depth;
• pressure force;

Choose a pump that is exactly for your sewage system.

• the diameter of the passage of the pipe, which will transport the masses in the septic;
• engine cooling method;
• location of nozzles.

The pumping of the pumping pump should play a key role when choosing a model. The higher the indicator, the faster, your pump will work better.

No less important aspect is the impeller device.

Attention. The performance of the knives is above the performance of the cutting edge.

In addition, some models provide for the self-cleaning system of cutting mechanisms, which perfectly affects the smooth operation of the pump.

You should also take into account the pressure of the pump maximum. Conditionally, the meaning is considered 10 m.

Installing a fecal submersible pump

So that the engine worked without overheating and coped with large loads, he needs good system cooling. So do not forget to pay attention to this when choosing a model.

The pump for pumping a sewage must be installed on the bottom of the reservoir. On the walls, the guides are mounted for the pump descent, and at the bottom - set a special nozzle. The unit itself is lowered using a cable or chain, the pump is planted on the nozzle due to its own weight.

Varieties of fecal pumps on the principle of work

The fecal pump must be selected depending on the type of sewerage and the presence of solid impurities in contaminated liquids:

• pressure;
• patching;
• vacuum;
• toilet with chopper.

Their difference consists in the principle of operation, the maximum permissible temperature of the removal of the fluid and the presence or absence of the chopper. The fecal pump with a special cutting mechanism is not afraid of blockages and is intended for pumping fluid with any solid inclusions not exceeding 3.5 cm in diameter.

Fecal pump with chopper

The principle of operation of this type of equipment is reduced to the automatic launch of knives, which are grinding in counting seconds, and then pump pumps the resulting liquid in the direction of the central riser.

Attention. Even if the subject fell into the sewer system by negligence, it will be grinding.

Forced sewage systems

If you have a very long distance between the source of sewage waters and the riser, you need to take care of the system of forced sewage. This is a fecal pump equipped with a shredder and accumulative capacity. As wastewater accumulates, the system automatically turns on the pump and shredders, and the masses are forcibly delivered to the sewage system.

Life in a private house has its advantages, but also requires additional work. One of them - ensure normal operation autonomous sewage. In order for you, you do not have unpleasant situations, you need calculate sewage regularly.Consider what modern equipment exists for such works and how to choose it correctly.

Essence of the process of pumping sewage

With an autonomous sewage system, dirty water flows into a cesspool or septic tank. The volume of pits or septicism is filled with time. wastewater And they need to pump out. Otherwise there will be a hole overflow, which will be accompanied by an unpleasant odor and can make unfortable to the entire sewage system.

You can roll out the contents of the septicity using special equipment, independently or contacting the specialists. There is a wide selection of pump pumping pumps, read their main characteristics.

Did you know? In the Japanese city of Suva from dry sewage sewage waste mining gold. Its concentration in the waste is 50 times more than in gold mines with traditional mining. The thing is that there are many electronics in the city, which contains a precious metal.

Equipment for pumping

There are two main types of pumps: fecal and drainage.

Suitable for pumping dirty water from a washing or dishwasher. Such pumps pump dirty water with a small content of solid particles.

differ in the diameter of the flow channels and can cope with dirty water together with feces and other solid particles in large quantities. Some models are equipped with special choppers, which grind solid particles of household waste.

Classification of pumps by installation method

By the installation method and the type of system there are submersible, surface and semi-loaded pumps.

Submersible

Submersible work as full immersion in wastewater.They are made of material capable of withstanding corrosion and exposure to the aggressive medium, the body is reliably insulated. Each model has its own maximum immersion depth, design type (horizontal, vertical). The pump is once recorded at the bottom of the pit with the help of an angular removal and guides.

Manage work is made using a remote control.

The advantages of such a design:

• the cooling system does not need;
• can work in winter time;
• minimum noise when working;
• works at large depths.

Disadvantages:

• complex installation and setup;
• increased electrical safety requirements, anti-corrosion and insulating characteristics of the case.

Surface (external)

Surface systems are located above the sewer well, and intake hoses are lowered under water. According to the design, they do not have shredders, they cannot be used to pump highly contaminated waters with large particles.

Benefits:

• easy installation;
• mobility.

Disadvantages:

• big noise level during operation;
• dependence on weather conditions (the pump does not work at a negative temperature);
• quickly overheats (there is no cooling system);
• low performance and short period of smooth operation.

Semi-grade

Semi-grade machines are immersed in estimates not completely, the engine is above the water surface. On the surface they are fixed using the float. In such models, the shredders are not provided.

Benefits:

• easy installation;
• mobility;
• high performance.

Disadvantages:

• water getting into the engine displays a pump;
• dependence on weather conditions.

Did you know? In 1516, Leonardo da Vinci for the King of France Francis I invented the toilet with the drain. But the invention was not embodied due to the lack of water supply and sewage systems.

Main types of fecal pumps

Fecal pumps are capable of pumping dirty, viscous liquid with solid particles up to 5-8 cm.They can be used not only to pump sewage, water from the basement, and for water circulation in large tanks, and for irrigation of the land.

Compact models can be installed in the house, close to the toilet, washing or shower. These forced sewage systems are used if it is impossible to provide the desired angle of inclination for the operation of the samotane sewage system. The aggregates patch the drains into a pit or septic tank.

Depending on the design, principle of operation and purpose, there is Several types of aggregates: With shredders and without them, to work with cold and hotstocks.

Pumps with chopper

Fecal systems with chopper are equipped with a special device that crushes solid objects in the waste fluid.

The system of the system is made of high-quality and durable materials. In compact container posted grinder and fecal pump. The system can be installed in the house, close to the toilet bowl, sink, shower or washing. The chopper grinds the solid waste into a homogeneous mass, and the pump pumped it in the desired direction. Check valve does not give the stamps to go back, special filters do not penetrate the room unpleasant smell. The system is connected to a conventional outlet 220 V.

Important! The temperature of the drain should not exceed +40° C, otherwise the system will fail.

Special systems that can work are used to work with hot wastewater. at the temperature of the drain to +95 ° C.Module for chopping solid waste allows you to connect the unit to dishwasher and washing machines, sink, shower, toilet bowl.

Powerful chopper knives perfectly copble with solid particles. Pump pumps drains into the sewer.

Such installation costs more, Through similar to working with cold runoff.

The pumps without chopper work with cold and hotstocks and are used for pumping cold and hot liquids without large solid particles.

To work with cold wastewater

Installation for working with cold wastewater is very compact and does not require much space. It can be connected to sinks and shower cabins. Differs low price, but temperature of stock should not exceed +40 ° C. It may diliate a dirty liquid without large, solid particles in the vertical direction up to 5 m and in a horizontal - up to 100 m.

To work with hot wastewater

Installations for working with hot wastewater without chopper are used to pump sewage drain from bath, dishwasher and washing machines, washing. The system is very compact, the powerful pump perfectly pumps hot dirty liquids, permissible temperature +90 ° C. Pump helps to establish a sewage system, if there is no needed inclination.

Choice rules

When choosing a pumping unit it is necessary to take into account the main characteristics:

• terms of use, installation type, flow temperature;
• performance, volume of waste, immersion depth;
• engine cooling;
• case material;
• the diameter of the inlet, the presence of the shredder;
• management method;
• self-cleaning of the impeller of the shredder.

For frequent or permanent use, the most suitable submersible models.And for rare use, you can choose a cheaper and less powerful surface type of pump system.

It is necessary to choose performance in accordance with the volume of septica or sewer well and the degree of fullness. Special attention must be paid to the maximum depth of the dive at which the pump operates in normal mode.

It is necessary to find out how the engine is cooling, and check the stability of the corrosion body.

The presence of chopper, the diameter of the inlet and the temperature of the stocks are some of the main selection criteriathe optimal model depends on how much contaminated drains and which temperature can be scrolled.

The most convenient method of control using the remote control. The presence of the self-cleaning function of the grinder mechanism is an advantage when choosing a model, but the cost will be higher.

Terms of Use

For efficient operation of the pump system, it is necessary to calculate correctly necessary power, do not overload the pump, but also do not use in the "dry".The diameter and slope of the sewer pipes are of great importance, as well as the correct septic design.

It is necessary to monitor the contents of septicists so that large and solid items, acids do not fall into the sewer.

When using surface and float units, it is necessary provide good electrical insulation So that the moisture does not get into the engine. And also ensure that it does not overheat, and do not use at negative air temperatures.

The deep pumps must be installed correctly and secured at the bottom of the pit.

Forced sewage systems installed in the house near kitchen Money, it is necessary Periodically purify from fat.

Preventive operational measures

It is recommended at least once a year, check the serviceability of the cable, the condition of the hull, at what distance from the bottom of the pit is the suction device to prevent capture of large and solid items, stones.

Preventive system cleaning will significantly extend the service life and will prevent breakdown.

Independent installation of the factory aggregate

Install the factory unit can be made alone You only need to adhere to the manufacturer's recommendations.

Submersible

Pumping equipment is installed almost on the very bottom of the sewer well. It is necessary to leave a small gap, so that solid items from the bottom of the well are not absorbed into the intake hole. To do this, there are metal supports on the housing, or a design with guides is used, the pump can also be suspended using a strong cable.

Rejected pipe is better made from plastic pipes diameter 6-7 cm, which can be disassembled if necessary. Flexible hoses are not recommended due to clogging. Light pipe it should be well insulated.

Be sure to install the check valve to avoid the return of sewage drain.

Connect K. electrical network It must be performed through the electrical protection, grounding, automatic machines from short circuit and current leakage. To ensure uninterrupted work in case of power disconnection, it is necessary install a diesel electric generator.

Surface

When installing the surface pump, it should be considered that for each model there is its maximum fluid lifting height. If the system is not permanently used, then you can place the pump on the edge of the sewage pit or on the site is not far away. The main thing is to ensure the protection of the engine from moisture. Surface pumps are poorly waterproof, and the slightest fallout can cause a short circuit and output, and the body may damage corrosion.

If it is planned for year-round use, the pump must be placed in a special room or use caisson.Installing the check valve and connecting to the power grid as the same as when mounting the submersible.

Semi-duty

Install submersible pump It is possible on a special platform next to the sewer jam, on a floating pad, or consolidated for one of the walls of the pit. From the length of the working hose depends the depth of immersion of the pumping part, the engine must be above the surface of the fluid. Used special float,which holds the engine over the water.

Maker to the power grid should be made through an electrical panel with automatic protection, grounding and shutdown machines.

Important! The diameter of solid particles in the drains should not exceed 1.5 cm, since the semi-duty pump does not have a grinding system, and the diameter of the flow channels is small.

First launch pump for pumping sewage

For the first starting system, you must fill the sewer well water Until the minimum allowable level for this model.Then increase the level before the float switch and the system startup is triggered. At this stage, you can adjust the level at which the circuit breaker will turn off the engine.

Modern sewage pumping equipment can significantly improve and make a more comfortable lifeowners of private houses and cottages. It is necessary to choose the most optimal option Depending on individual needs. For proper choice Models, installation and operation, the equipment will last for many years, solving an important issue of work sewer system.

Before choosing a drainage pump for sewage, should be understood in the features of the design of this category of pumping units. Not in all cases, their use in this direction is permissible. Even if the use of the drainage model is justified, the efficiency of the sewer system largely depends on how much you choose and install the technique.

Drainage and fecal pumps: similarities and differences

Those who choose equipment for sewage, it is important to understand that the drainage pump differs from fecal according to its technical characteristics, despite the fact that both types of pumping pumps are intended for transportation of contaminated liquids. The main difference is maximum allowable size of insoluble inclusions.

Usually, when classifications are called the following parameters:

• drainage sewage pump able to pump up the drains with solid inclusions up to 3-5 cm,
• Correctly cope with solid and long fiber particles up to 8 cm.

It is important to remember that the limit values \u200b\u200bdiffer from different models Pumps and are indicated in the technical characteristics of each unit.

Another important remark for those who decided to buy a drainage pump for the sewer system - fecal models are usually equipped with chopper. This device, which is an impeller, blades destroys insoluble inclusions, preparing the drains to trouble-free transport. In addition, the impeller grinds capable of doing the performance of the pumping unit of fibrous inclusions, such as toilet paper. Drainage models of pumps of such a supplement do not have.

Advantages of drainage pumps

A natural question arises: if fecal pumps cope with the pumping of polluted drains, why do you even talk about whether it can be replaced by a drainage pump to pump sewage in a private house?

The fact is that drainage pumps have a number of benefits.

1. They are cheaper than fecal models.
2. The overall dimensions of the drainage products are less.
3. The market shows more drainage models of pumps than fecal, which makes it possible to accurately choose the option with the necessary technical specifications.

Scope of application

Based on the functionality, it can be understood that the drainage pump is not suitable for the transportation of stocks directly after the toilet. Callery masses and toilet paper are able to cause the mechanism, serious breakage and expensive repair. In the septices, as a result of life, large inclusions are converted into il and water, that is, they change not only their composition, but also dimensions and consistency. To pump such purified drains, you can use a drainage pump.

In order to understand how to choose drainage pumps, you should figure out the variety of models using the classification.

Note: Surface and semi-submerged pumps can be installed stationary (connection to the system using pipelines) or be mobile (connection through flexible hoses).

• Submersible pumps Not just under the surface of the liquid in the tank, but also located at a depth (as a rule, in the installation instructions for each model, the required distance from the bottom of the unit to the bottom of the container is indicated). Such pumps are installed inpatient, fall into the tank on the cables and are attached to metal guides. One of the advantages of the submersible model is low (compared to surface vehicle) noise level.

Depending on the type of power, drainage pumps are distinguished:

• single-phase in the possibility of lifting liquid from a depth of up to 24 meters and performance depending on the model up to 800 l / min.
• three-phase with limit values \u200b\u200bof 150 meters and 6500 l / min, respectively.

Materials for manufacture

The qualities and characteristics of drainage pumps depend on the material from which the model is made.

• The most reliable and durable are metal pumps, where metal (stainless steel or cast iron) are made as a working part and a housing.
• The cheapest products are plastic, however, taking into account quite complex conditions of operation, the timing of their trouble-free service is much less than that of metal models.
• Compromise option can be considered combined pumps, the metal working part of which is placed in the plastic case.

Operating principle

The principle of the drainage pump is based on the creation of a low pressure in the chamber. Rewards are formed when the impeller rotates, as a result, water enters the chamber, where the centrifugal force is accelerating and the direction of movement. As the fluid outflows in the output, the low pressure region is reappeared in the pump chamber.

Automation of drainage pumps

It is impossible to control the pump manually. Monitoring the water level and equipment status, the inclusion and turning off the unit would require the permanent participation and presence of the user. Therefore, the patching equipment is supplied with devices that control and manage the parameters of the work. Domestic drainage pumps for pumping sewage is usually equipped with a "subsistence minimum" - the most necessary for efficient operations.

• Floats - Simple, inexpensive and trouble-free method for determining the level of fluid in the tank. The sensors installed on the floats include the unit when the container is filling and disconnected when the level has decreased enough.
• Termorelay It works in cases where the temperature of the technique increases. This eliminates the likelihood of overheating and failure of equipment.

Industrial models of drainage pumps can be equipped with more complex and accurate control devices that are expensive, and their use in domestic conditions is economically inexpedient.

The starting point when choosing a drainage pump is a set of operating conditions. The acquired unit must comply with them without fail, otherwise the work of the sewer system will be ineffective.

Of great importance are:

• the composition of the liquid, the amount, the type of impurities and the dimensions of their particles,
• temperature waste
• the presence of aggressive substances in the pumping fluid (for example, if the decomposition of impurities in a septic or a cesspool is carried out not by biological, and in a chemical method),
• the amount of incoming incoming (based on this parameter is determined by the required pump performance),
• reservoir depth
• estimated pump installation location,
• distance to transport liquid to transport
• operating mode (permanent, seasonal, periodic).

For clarity, you can give an example of calculating the parameters.

Each meter of the distance horizontally, to which the drains must be moved, corresponds to 0.1 M height of the pressure.

Thus, during the fence of the drain from a depth of 2 m and transporting it to a distance of 10 m, the pump head should be at least 2 + 10x0.1 \u003d 3 m.

Pay attention to the equipment package - it should include a float sensor and a thermoster. Optimally, the presence of a second spare float, which will work in the event of a breakdown of the first.

Popular manufacturers

Experts insist: only the technique of well-known and proven brands will ensure the trouble-free operation of the sewage system and will be more economical due to their durability and reliability.

• Any drainage pump for sewage Grundfos. Differs in multifunctionality and low noise. Grundfos aggregates are compact, reliable and do not represent complexity during operation.
• Most likely, not all Russian users consider a significant advantage. stylish design drainage pumps Djillex (Drainager series). However, few people will remain indifferent to the operational qualities of the aggregates of this brand (low noise, durability, the ability to work in difficult conditions, compactness, acceptable price). Another advantage of brand products is the adaptation of models to work in Russian conditions.
• Submersible drainage pumps Nocchi. Equipped with float sensors and are distinguished by a wide range of applications. The advantage of the brand pumps is the presence of a self-cleaning system, which simplifies the maintenance of technology and increases its disavarian operation.
