The best fecal pumps with a grinder. How to choose a septic pump for cesspools

03.03.2020

Fecal pumps, or as they are also called - a submersible fecal pump, are specially designed for pumping contaminated water with inclusions of various sizes. Here are some examples where they are actively used.

Pumping of sewage, fecal waters, sewer discharges,
- pumping out the contents of cesspools and flooded basements - especially important for private houses and summer cottages in the absence of a centralized sewage system.
- pumping out flood waters with a large amount of small debris - grass, silt, clay, etc.

The sewage pump does not have to be used only for heavily polluted water - it is quite versatile and can be used, for example, to supply water from small pond, which is relatively pure but still contains inclusions.

What is a submersible fecal pump

The fecal pump, like other pumps, consists of a housing, an electric motor and a working impeller, however, its distinguishing feature- resistance of the body to the impact of abrasive and chemical impurities, the presence of a chopper knife in front of the inlet, a fairly high performance.

The body is usually made of cast iron or stainless steel. Sometimes, if it is a household lightweight option, it is made of high-quality wear-resistant plastic. The impeller and shaft of such a pump are also made of stainless steel, or ordinary, but covered special composition to improve abrasion and chemical resistance. The size and nature of impurities that may be contained in water are indicated in the specification (instruction) for each pump, these can be both solid and fibrous (grass, fibers of various lengths and nature) inclusions.

Fecal pumps are divided into the following classes:
- outdoor fecal pumps- the pump is located on the surface, the pumped water is taken through a hose or pipe
- submersible fecal pump - its body is completely immersed in water.
- semi-submersible fecal pump - installed vertically, some models have special legs for installation.

According to the areas of application, household and industrial fecal pumps are distinguished. Industrial modifications have a larger bore diameter, greater power and productivity, as well as a more advanced grinding system. Household models are more mobile, they are easy to install where necessary, easy to use, equipped with several degrees of protection.

How to choose a quality and inexpensive fecal pump

Among the variety of such pumps on the market, it is difficult to immediately decide. There are many companies offering Italian, German, Danish, Chinese pumps with a large number of modifications. The price of a fecal pump in this case varies depending on the technical characteristics and materials from which the pump housing, its impellers and shaft are made, the availability of control and protection options. Naturally, when pricing, there is often a surcharge for the "brand".

If you just need to buy a fecal pump for your home or garden, pay attention to the following indicators:

Pump power (more powerful model consumes more electricity)
What material are the casing and impeller made of? Stainless steel is the key to a longer service life. Cast iron or plastic is also normal, it all depends on the intensity of use

If you are the owner of a country house or summer cottage, then you probably faced the question of how to solve the problem of getting rid of polluted drains. An excellent solution is to use a household fecal pump equipped with a grinder. With it, you can conveniently pump out drains.

The need to use a fecal pump

The fecal mass pump is simply indispensable in cases where there is a problem in arranging a septic tank. With the help of pumping equipment, you can easily solve the problem of cleaning the cesspool. Such devices work even with those contaminants that have foreign inclusions such as grains of sand, stones and solid debris. Water at the same time may have the remnants of dirt, silt, as well as household waste. The faecal mass pump will make it easy to solve the issue of maintenance or toilet. With the help of this unit, it is possible to clear pits and tanks from precipitation, empty the outdoor pool for the winter period, and also eliminate spring floods in basements and basement floors. If you are the owner of a house where the internal sewerage is equipped with pipes that have a small diameter, then the use of the equipment described will be simply necessary.

Key Features

If the described equipment is installed behind the toilet bowl, then it can easily grind all kinds of particles that will be brought to a centralized riser. A fecal mass pump may also be needed for the smooth operation of the sewage system, which is installed in public places. This is especially true when the daily flow of visitors puts a strain on the system.

Main Pump Selection Factors

If you decide to purchase a faecal pump, you must decide what tasks the equipment will perform, as well as what loads will be assigned to it. Professional and domestic installations designed for contact with acids, alkalis and aggressive liquids. If we are talking about household pumps, then the parts and assemblies in them are made using impact-resistant plastic that is resistant to chemical attack. If a more impressive load will be placed on the equipment, then a device whose body is made of cast iron or stainless steel should be preferred. Thanks to these differences, the unit will be characterized by higher operational characteristics and will last for a long time. When choosing a pump for fecal matter with a chopper, you should pay attention to performance, in many respects this parameter depends on power. When choosing a device, it is necessary to focus on the number of people who live in the house, and on the maximum depth of the cesspool.

What else to pay attention to?

It is important to take into account when choosing productivity and the distance to the point where sewage will go. If these characteristics are taken into account, then it will be possible to eliminate the possibility of unnecessary expenses, since the difference in cost between devices can be impressive.

Expert opinion on when to choose a submersible pump option

The faecal pump with grinder can be surface, semi-submersible or submersible. Such equipment can be installed permanently or temporarily, in the latter case we are talking about carrying out one-time work. The submersible type of pumps is a monoblock, which must be completely in a liquid medium and installed at the bottom of the storage tank. A household submersible fecal pump, according to experts, should be purchased by consumers who set the device for the task of periodically pumping wastewater. Here we can talk about a cesspool or cleaning the toilet. If you are interested in high performance, then you should choose this particular variety, which has found its wide distribution in industry and the private sector. Experts say that such pumps have no competitors in terms of waterproofing and resistance to adverse environments. The described pumps for fecal matter, the photos of which are presented in the article, can easily lift 400 liters of liquid to a 20-meter height within an hour. This is true for units with a power of 40 kilowatts.

Consumer reviews of submersible pumps

When faecal pumps are installed, users consider it necessary to ensure seat which is equipped with steel guides. With the help of them, you can easily position the equipment in the right direction. Home craftsmen are advised to provide for a strong cable or rope, which is useful for lowering the device. According to users who have been operating for fecal matter for a long time, the only drawback of such equipment is the limitation temperature regime. Due to the fact that the pump motor is cooled by the pumped liquid, its temperature should not be higher than 40 degrees. Only in this way, according to consumers, it will be possible to exclude the possibility of overheating of the motor when running dry. A number of models are equipped with a system automatic shutdown, which is activated by

If you decide to buy a pump for fecal matter, reviews of which you must read in advance, then you can tilt your choice towards semi-submersible equipment. Such devices must be installed on the surface using a special float. The pump part is placed in the drain, and the engine remains outside the cesspool. The length of the hose limits the immersion depth of the device. Experts emphasize that it is enough important point is a small diameter of the channels of submersible pumps of the domestic type. This limits the scope of use of this equipment, since the units are rarely equipped with cutting mechanisms. As a rule, such equipment is used to remove liquid wastes and those that have oil inclusions. Among other things, such equipment can be used to clean toilets from feces with solids. The latter can have a diameter within 50 millimeters. These fecal pumps are most often made from materials that do not effectively resist corrosion. However, if we focus on the principle of operation of such units, then given parameter should not be emphasized.

Expert opinion on surface aggregates

If you are looking for a fecal pump for giving, then you can also choose a surface unit. Such models have a cutting mechanism, which is located near the outer edge of the cesspool. Only the hose will be immersed in the liquid. According to experts, such pumps are easy to install. Among the main positive features of such units, an insignificant cost can be distinguished, especially when compared with other types of fecal pumps; as well as the possibility of using the unit for cleaning toilets and cesspools, which are located at a distance from each other.

Life on suburban area or just in your own home - this is an opportunity to relax from the hustle and bustle of the city. However, in addition to pleasant moments, there are problems of water disposal and sewerage.

A septic tank is needed, into which water from the house and, of course, fecal water will be diverted. After all, it is not very pleasant to catch the smell emitted by cesspool located in your area.

A suitable electric pump must be used to pump out the faecal water.

Types of fecal electric pumps

For right choice fecal pump you should know that fecal pumps are:

submersible;
semi-submersible;
superficial.

Submersible

Submersible fecal pumps are somewhat different from conventional ones. They are capable of pumping out fine debris and solid particles up to 500 mm in size, depending on the model, along with water. With their help, not only septic tanks and pits are pumped out, but also pits, basements, water is supplied from rivers and lakes. Sufficiently large power on almost all models will ensure the implementation of this process in the shortest possible time.

Quite often, private houses cannot be connected to a centralized sewer, or it goes far, is completely absent, or the slope of the pipe does not allow this. A smart owner knows that the drainage of water through pipes from the house should take place with a slight slope. In such cases, a septic tank or a cesspool comes to the rescue, in conjunction with which, to ensure your comfort, a fecal pump has been created.

Considering that this type of pump will function in aggressive environment, then the material for its production is selected appropriate: the body is made of cast iron or stainless steel. A fecal submersible pump with a grinder installed at production facilities has become an integral part of them.

Since fecal submersible pump will be below the liquid level, then such instances are equipped with special float systems that turn off the pump when the set liquid level drops. It descends into a pit or septic tank on a cable, and a hose is attached to the pump through a fitting, which is led to the required place.

Semi-submersible

A semi-submersible fecal pump is located on the surface of the liquid using a special float. The engine is above the water, and the pump element itself is immersed in water. The maximum diameter of passed solid particles in such samples is not large, therefore, a special grinder is used with it.

However, for domestic use, even without it, he can easily pump out decomposed masses in a septic tank, with debris and particles up to 15 mm.

Surface

Fecal surface pumps have slightly worse characteristics than the previous two types. Their power is lower, as is performance. The throughput of solid parts does not exceed 5 mm.

The advantage is high mobility and ease of use, as well as their price is much lower. An external fecal pump is well suited when pumping is required more than once a quarter. Basically, they pump no more than 1500 liters per hour.

The electric pump itself is installed on the surface (near a cesspool or septic tank), only a hose is lowered into the water. It is not used for permanent use, as it can fail if atmospheric precipitation hits it. It is recommended to bring it into the room after pumping out the liquid.

There are times when such an electric pump is installed under a canopy, but the moisture in it will freeze in winter, and the pump will fail. It is much better if it is installed in a heated room next to the well.

Electric pump with grinder

It is best when installing a fecal pump for pumping out to consider all the points that will affect its operation. Some models pump out 1100 liters per hour and others 1500 liters per hour.

Production samples with large dimensions are capable of pumping out much more liquid in a short period of time, however, their water intake depth generally does not exceed 6 m. With a power of 250 W, which is not very much, they are able to squeeze water up to 50 m. A feature of this type of fecal pump is that it can be used at large facilities or purchased one for several houses or cottages.

Living in a private house, cottage or other residential facility that is not connected to a centralized sewer, it should be understood that one cannot do without water drainage and a cesspool or septic tank. As well as without a fecal electric pump, selected in accordance with the conditions in which it will be operated. A competent choice and proper prevention will help you forget about the problem of pumping out a cesspool and a septic tank with help for many years.

country house or country cottage can not do without a reliable sewer system. Progressive hydraulic devices, which include a fecal pump with a grinder, help to ensure its uninterrupted functioning. It has several options of execution suitable for specific working conditions. What is it and how to choose the right unit - in our article.

Ways to use

The device has multipurpose use in domestic and industrial conditions. It is mounted for seasonal pumping in the warm season in the following cases:

emptying the cesspool;
pumping out of tanks with a septic tank;
cleaning containers with stagnant contaminated water.

The built-in mechanism is able to grind not only fibrous structures that enter the sewer, but also perform other work for the dacha. Knives easily crush organic elements found in water:

grass or fallen leaves from trees;
seaweed;
particles of household waste and so on.

The resulting fine mixture does not load the pump motor and increases the throughput of the connected pipes.

Due to the fact that the fecal pump with a chopper for cesspools cuts the falling debris literally into millimeter fragments, the risk of jamming is reduced. This feature allows you to use the devices in the transportation of such liquids:

rain or storm drains (contain leaves or small branches);
drain from the sink (there are leftovers of food);
withdrawal dishwasher(large particles come across);
toilet sewage - waste products, toilet paper, foreign objects, etc.

A variety of faecal pumps with a grinder are needed for places where the sewer system is used uncontrollably by a large number of users, in particular, we are talking about public toilets.

Foreign solid objects can also enter pipes in catering establishments, campsites or factories. Pumping of water by units of this type is carried out from natural reservoirs for their partial drainage or for the selection of liquid. Silt or algae can enter inside. You can not do without additional cutting in systems with channels with inside diameter less than 80 mm.

Construction and basic elements

To obtain a fine fraction from organic and inorganic residues, a cutting unit is installed in the structure. It has several versions:

the blades of the screw impeller, which has a conical shape, are sharpened on the outer side;
sharpened blades pass closely along the polished end of the output cylinder, providing the effect of scissors;
coaxial to the diameter is a pair of knives that processes incoming debris;
the cutting module is mounted next to the hole and rotates through an additional gearbox.

The rest of the design resembles a conventional drainage pump. The design also includes:

Electric motor. Household products operate on 220 V, industrial items are designed for 380 V.
Frame. Different specimens are made from different materials.
Fence part. Allows fluid to pass through without blocking the inlet.
Outlet pipe. It allows you to connect to the pipeline for further transportation of the liquid.

An important feature that the septic pump with a grinder for cesspools has is the use of materials resistant to external influences for the body and working units. They must withstand mechanical and hydraulic loads, as well as not be destroyed by chemicals. The stable body must not be destroyed by fine sand working as an abrasive.

The body material is:

Stainless steel - this material practically does not corrode.
Cast iron - a powerful body can withstand significant mechanical stress.
Plastic - used in budget models, resistant to chemicals.

Knives are made only from high-alloy stainless steel. They have an additional protective coating.

Equipment functionality

It is clear that the main function of the fecal apparatus is to pump out contaminated liquid from the sewer, and it is for this purpose that it is most often purchased. But with other tasks, he copes with 100%. This is the potential for:

When the house is located in a lowland, any heavy rainfall leads to flooding of the basement and basement floors. Self-priming equipment is capable of pumping out water with solids, including small stones.

If flooding is observed regularly, it is possible to make pits or storm drains in the basement or basement, where to place the unit. And if you choose equipment with a float, you don’t even have to pull it out - it will turn on as the pit fills up.

It is convenient to use a pumping unit for cleaning drainage pits or collectors. It is also convenient to use it for pumping out the septic tank chambers in order to pour liquid into the filtration field.
If there is a river or lake nearby, using fecal equipment with a chopper, you can draw water for irrigation or other technical needs. Strong steel knives are able to cut any solid inclusions, not counting mud, algae and branches, therefore, there will be an excess of water purified from foreign objects on the site.

Varieties of models

Each sump pump with grinder belongs to one of three major groups. The main difference between them lies in the installation method:

Submersible pump. It is located at a shallow depth in the liquid column. The main advantage is the processing of waste up to 45 mm in diameter, it also has a significant lifting capacity. The disadvantage is uncomfortable maintenance and repair.

Submersible models - the most popular in the household

Surface fecal pumps with grinder. They are based on land, and the intake fluid enters through a special pipe or hose with a diameter of more than 60 mm. Convenience lies in the fact that you can pump out liquid from a container with a small diameter. It is enough to lower the intake sleeve there. You can permanently place the device near the toilet, kitchen or bathroom.

Surface equipment is quite bulky and very noisy compared to submersible products - they are mounted outside the house

Semi-submersibles. Rare examples have a shredder, as the maximum diameter of possible contaminants is limited to 15 mm.

In addition to household appliances, industrial installations are used. They are mounted in institutions, enterprises and organizations.

When choosing a product for pumping liquid from the kitchen or from a dishwasher, it is necessary to select an instance that can transport hot liquid with a temperature of up to 80-90 ° C.

Type of operation

Installation is carried out depending on the method of use. In some households, pumping is used regularly, somewhere from time to time.

In the case of stationary operation, it would be appropriate to use a submersible fecal pump with a chopper or use a semi-submersible type unit. Dismantling for them will be needed only for the period of maintenance or repair. They will be most comfortable in a prepared receiving well. The diameter of the hole must be at least half a meter. All taps from the bath, kitchen, bath and other places are connected to such a tank.

It will be necessary to configure the system for pumping out depending on the degree of filling of the well. After the waste is removed, the automation is supposed to be turned off so that air is not trapped.

If pumping involves long breaks in time, then it is worth using a submersible pump with a small device in the form of rigid guides. In addition, a cable for pulling is attached to the device.

Vertical posts provide the right position for work. Moving along them, the device descends to the very bottom of the pit. After work, we take out the unit, clean it and dry it. It is preferable to store it in a dry, warm place, such as a utility room, garage or pantry.

Main evaluation criteria

If you need a fecal pump with a chopper for cesspools or pits, you should focus on certain parameters. Among them:

Power and voltage

Most modern household equipment is powered by a standard 220V power supply. Power defines it functional characteristics- column height, pumping speed, grinding fraction, etc. This information is reflected in the technical data sheet of the product and must be studied.

Example. If you need a fecal pump with a grinder for the sewerage of a small country house, which can also be used to pump water from a basement or drain, then equipment with a capacity of 500 watts will do just fine. And if you need equipment that will work constantly and “serve” a family of several people, the power of 1-1.5 kW will be optimal.

Performance

This is the volume of pumped fluid per unit of time. For all types of suction equipment, this figure is measured in liters per minute. An ordinary household unit with a power of 500 W pumps about 150 liters of liquid per minute, and 1.5 kW equipment pumps 650-700 liters. This means that even when large volume it won't take long to work.

Pressure post height

It is usually measured in meters. For pumping devices, this indicator indicates to what height the water column rises at the time of pumping. And if for ordinary submersibles this is a unit of vertical execution, then for fecal - horizontal. Considering that you often have to work with heavily contaminated liquids, the average indicator is taken as a basis - 1 created pressure ensures the movement of water at a distance of 3.5-4 meters.

For domestic needs, 10-15 meters of water column is enough.

What is the body made of

The absolute priority is metal, as it is many times stronger than even the highest quality plastic, although modern polymers have repeatedly confirmed their strength. More expensive specimens are made of stainless steel, simpler ones are made of cast iron. We are not even talking about ordinary steel, since feces and sewage are too aggressive in terms of chemical composition for a steel case to cope with this for a long time.

Cast iron fecal appliances with a grinder are very massive and heavy, so carefully choose the thickness of the rope. In addition, cast iron is a brittle material and can burst when receiving an accented blow.

The presence of a float (water level sensor)

Even if the unit is not supposed to be used in automatic mode, the presence of a water level sensor with a shutdown function will protect it from emergency operation outside the liquid medium.

Immersion depth

It is clear that lowering a suction unit of a certain power and capacity to a greater depth than technically calculated, and expecting it to work normally, is at least strange. Each sample has its own distance parameter to the water surface, and this is reflected in the data sheet.

Size of solids

Since this is a fecal pump with a grinder, there is a certain diameter of foreign matter that it is able to grind. For domestic needs, it is enough to choose 20-30 mm, this is an excellent indicator.

Please note that it is the size of the solids that matters, not their hardness or density. Knives are able to grind even stones.

Operating environment temperature

Depending on the environment in which it is planned to use the drainage device - hot or cold - the operating temperature is also chosen. Cold indicator - up to 35 ° С. Hot - up to 90°С.

Rating of the best models of fecal pumps with a chopper

Consider several popular popular devices that have managed to establish themselves in the domestic market of hydraulic pumps:

Gileks 150/6

Russian manufacturers offer a budget sample for 3,000 rubles. It belongs to the household type and can be used to pump out the sewer in the house. The power is 0.4 kW with a maximum head of 6 m. It operates from a household electrical network of 220 V and is capable of passing up to 9 m 3 / hour. Stainless steel body.

Grundfos SEG

German assembly and high quality are noticeable in professional equipment for 50,000 rubles. The cast-iron body is equipped with an overheating protection system and is protected from the action of corrosive processes. The power is 900 W, and the throughput reaches 15 m 3 / hour. It starts from a voltage of 220 V. It works at a depth of up to 10 m.

ESPA Draincor 180

Spanish installation, providing an excellent ratio of price and quality among analogues. Resistant to various environments, operates at a minimum noise level. The body of the apparatus is cast iron. Power is 1.7 kW. The pressure reaches 12.5 m. It is able to withstand voltage drops of 220 ± 10% V.

For a fixed connection in the toilet, the Grundfos Sololift2 line is used. Starting and stopping it is carried out automatically after the liquid enters the working cavity. Installation is mounted directly behind the toilet.

A fecal pump is a type of equipment that is little known to the layman. And only when faced with the need to clean the cesspool or drain the home pond, the owners begin to think about what pumping equipment they need to purchase. In most cases, the buyer has to rely on the honesty of the sales assistant who advertises a particular brand.

It is not possible to check how honest this person is. After all, the owners of a country house want to solve the pumping problem as soon as possible dirty water, and there is absolutely no time to read the technical instructions.

The pump can be installed once at the very beginning of using the sewer, thereby ensuring independence from the sewers in the future.

Often, a pump for pumping fecal effluents is confused with drainage units.. Fecal pumps are more versatile devices that can cope with liquids of any degree of pollution, including silty bottom sediments - their pump also raises them to the surface without any problems. But the classic application is, of course, the organization autonomous system sewerage in the country or in a country cottage.

Any fecal pump is a compact pumping station for pumping, processing and further transportation of sewage waste. The unit can move liquids of a viscous consistency both in the vertical (up to 7 m) and horizontal (up to 100 m) directions. For the manufacture of housing manufacturers budget models more commonly used impact-resistant plastic. Protection against dry running is carried out through a float that controls the level of liquid in the cesspool or sewer.

According to the technical characteristics of the pumps are:

equipped with a chopper (knife) or designed without this mechanism;
operating in cold or hot water.

Hot drain units work well with relatively clean water. They are often installed indoors - they are used to pump water from a bath, shower, washing machine and dishwasher. Such pumps are usually not equipped with a shredder, but there are more expensive models with knives that can cut paper and hygiene items that have fallen into the sewer.

Devices with a grinder for cold water work with liquids at temperatures up to 40 degrees. The chopper is located in the upper part of the body - this is the only drawback of such models. With the upper location of the knife, not all large particles of mechanical impurities are processed into a homogeneous mass, which complicates pumping.

The principle of operation of such pumps is the same for all models. Runoff water enters the basket, on which large debris settles. Fluid flows into the pump and starts the motor. If a grinding mechanism is provided, it is set in motion simultaneously with the pumping of sewage waste.

Primary requirements

One of the main conditions for choosing a fecal pump is the size of the mechanical particles for which the unit is designed. This parameter must be specified by the manufacturer.

The fecal unit has enlarged flow channels that can pass through garbage up to 8 centimeters in size.

All are conditionally divided into four groups depending on the area of their application. Each individual group has its own requirements, which were initially taken into account by manufacturers:

Without grinding mechanism for cold water. The pump operates at temperatures up to 40 degrees. This is the cheapest model on the market, designed for pumping liquid from pools, basements, cellars.
Without chopper for hot water. The units are capable of operating at a temperature of 90 degrees. Are established on drains in baths and saunas.
With grinder for cold water. Working temperature 40 degrees. These pumps are the most popular on the market. Are established on the drains taking away faecal masses from toilets. Feminine hygiene items, hair, toilet paper.
With grinder for hot water. The device operates at temperatures up to 90 degrees and is perfect choice for installation in baths and saunas equipped with a toilet.

Also, the equipment is distinguished by the type of installation:

on the surface (a suction hose is lowered into the pit);
full immersion (the unit is fixed at the bottom of the pit using guides);
partial immersion (installation according to the float principle) - the engine remains on the surface, and the pump compartment is immersed in the liquid.

Inexpensive pumps, easy to use. At maintenance the unit does not need to be washed from the outside from dirt - it is inside. I consider this the main advantage of surface models.

Our model is SM 80-50-200/2. Works with impurities up to 5 mm and at a temperature of 90 degrees. They put it in an insulated caisson near the house. We use for pumping water from the bathroom and toilet. Not a single failure in two years.

Calpeda

The Italian brand, which has been present on the world market for half a century and has earned the trust of customers, offers semi-submersible models of fecal-type pumps. This line occupies the middle and high price segment. Productivity from 3 to 30 cubic meters per hour. Head from 4 to 11 meters with vertical supply.

Can be installed up to 2.5 meters deep.

Advantages:

wide range of;
economical power consumption;
reliability and ease of operation.

Disadvantages:

high cost of more productive models;
inability to work with great depth;
can not be used for pumping contaminated fluid with large impurities.

The price is from 47,000 to 115,000 rubles.

High quality pays big money. Calpeda offers exceptionally high quality pumps. Very happy with the build. We use the SC 30/1250 model. Its body is made of cast iron, and the impeller is made of brass.

For an amateur pumps. It is very unusual that the impeller open type. I think the price is too high, given the technical characteristics. The pump is "too tough" with water interspersed with mechanical impurities up to 3 millimeters in size. The operating temperature is only 40 degrees. It will not be possible to pump water from the sauna with such a device. And use it for pumping public sewerage also not worth it - suddenly clogged?

Proper operation

Regular use of the pump for pumping fecal effluents implies compliance with all specifications indicated in the instructions!

Owners need to pay attention to the following parameters:

immersion depth for submersible and float (semi-submersible) models;
on the pumping feature and the generated power (for models with vertical liquid supply, the average is 7-10 meters, for horizontal models - up to 100 meters);
energy consumption - quite economical household-type pumps with a capacity of 220-370 watts are produced;
on the size of mechanical impurities - it can be from a few millimeters to 8 centimeters;
temperature of the working environment - from 40 to 90 degrees;
the presence of a grinding mechanism (it is impossible to install models without a knife in drains with large mechanical impurities);
