The best fecal pump with grinder. Fecal pumps with a grinder: review of models and prices. Working environment temperature

Cleaning waste containers from contaminated water is a serious issue. The use of conventional pumps for pumping water is impossible here due to the increased viscosity of the liquid and the presence of solid and fibrous substances in it. For such types of work, fecal pumps with grinders, or as they are also called fecal pumps, were specially designed.

Centrifugal pumps are used as the basis for the production of fecal tanks with grinders. The shredder mechanism uses additional impeller with cutting edges. The grinder device can grind solid particles with a fraction of no more than 8 centimeters.

Classification

Depending on the design, pumps can pump both cold liquids, no more than 40 degrees, and hot liquids, up to 90 degrees Celsius.

Depending on the installation location, fecal pumps can be divided into 3 groups:

Surface installation.
Semi-submersible installation.
Submersible installation.

Surface method

Surface devices are the most powerful. They can create the highest pressure and flow rate of the pumped substance. Not that important to them overall size, as for other types of similar units. Such units can be driven by either an electric motor or an internal combustion engine.

For surface pumps there is no need to make the pump and motor housings from alloy steel. Only the supply hose, through which the liquid and the impeller are supplied, comes into contact with the pumped wastewater. There are types of units capable of connecting directly to a source of fecal water. For example, to the toilet.

When choosing a model, you need to pay attention to the following parameters:

Motor power
Maximum suction depth.
Created outlet pressure
Diameter of inlet and outlet pipes.

Depending on the engine power, installation requirements change. For low-power household pumps, just a flat surface is suitable. Further, progressively. The greater the power, the more seriously the foundation will need to be prepared. The most powerful feces are placed on a buried concrete foundation and attached to it through vibrating inserts.

TO positive aspects The uses of surface installation include the following:

Unit mobility. Possibility of use on several objects. Where occasional use is required.
Easy to install and operate. There is no need to create a special seat for operation.
Low price. Due to the absence of contact of the housing with an aggressive environment, there is no need to manufacture the outer housing from alloy steel or cast iron.

In addition to positive qualities, surface pumps also have negative aspects:

Quite a lot of noise is created from the switched on unit.

Seasonal use. At severe frosts In a fecal pump located in the open air, the pumped liquid may freeze.

Semi-submersible method

The installation principle of a semi-submersible pump is based on partial immersion in the pumped liquid. With this installation, the pump itself is immersed in the liquid, and the electric motor remains on the surface. Basically, this type of equipment is used for pumping liquids from shallow depths.

To use when the depth of the tank is sufficiently large, it is necessary to mount a floating platform like a raft. Then, when pumping out liquid, the platform itself will lower following the liquid level. The cost of such pumps is higher than that of surface pumps.

During manufacturing, it is necessary to use alloy steel not only for the pump impeller and grinder disk, but also for the pump body.

When choosing a semi-submersible type of equipment, you need to pay attention to the following points:

Electric motor power.
Created outlet pressure.
Volume of pumped liquid per hour.

The positive aspects of using this type of equipment include the following:

Opportunity mobile operation.
Opportunity operation in small volumes of liquid, where it is impossible to operate surface or submersible pumps.

TO negative qualities The following points include:

Seasonality of operation.
If necessary pumping liquids with a large reservoir depth requires additional equipment.

Immersion method

This type of equipment belongs to the most difficult segment of pumps to produce. When producing this type, it is necessary to use special steels for all parts included in the equipment.

In addition to protection from aggressive media, it is necessary to ensure the tightness of all connections to prevent liquid from entering the electrical part of the pump. The insulation of the supply electrical cable must also withstand exposure to aggressive environments.

Taking into account all the production requirements, this type of equipment is the most expensive. This type is used only permanently.

To install a submersible sewer with a grinder, you must perform the following steps:

Securely fasten load-bearing beam above the tank. The beam must be selected taking into account the weight of the pumping unit and the outlet pipe. The beam must pass through the center of the tank.
On the surface connect the outlet pipe to the outlet pipe.
Connect pump with a beam using a steel cable or chain. The length of the cable or chain must be equal to the installation depth of the unit.
If necessary provide lifting mechanism to remove the unit from the tank for repairs or replacement.
Connect the power supply cable from the distribution board to the installation site.

To the positive aspects of use submersible unit The following factors can be included:

Opportunity operation all year round.
Absolutely no noise produced during work.

The negative aspects include the following:

Difficult to install.
The need to remove the unit from the tank for repairs.
High cost.

How to choose the right equipment?

To select the right equipment for a particular facility, you need to consider several important points:

Frequency of use.
Tank location.
Volume pumped liquid.
Liquid lifting height or, in the case of surface or semi-submersible units, suction lift.

Let's look at an example:

If it is necessary to periodically pump process water in small quantities, then it makes sense to use a mobile surface option. Also, it is perfect for use in enclosed spaces. This type of equipment can be mounted directly to a storage tank located in the basement of the building.

In case of periodic operation at different points, a semi-submersible type of equipment is better suited. This type of unit can be multifunctional. It is suitable for collecting water from a shallow reservoir and for periodically cleaning household sewer pits.

For stationary use in large-volume sewer pits, it is better to use submersible fecal dumpers with a grinder. Especially if they are located far from housing. At proper organization use, these units can be used in fully automatic mode.

Removing waste from cesspool a private home is quite a complex matter, given modern realities and the possibility of various types of large debris getting into the waste, which can damage sewerage equipment. Therefore, it is used to remove waste special equipment– with a chopper.

The main task of this sewerage equipment, removal of waste from the cesspool. The grinder, built into the mechanical part of the device, facilitates this task by cutting and crushing solid inclusions that are present in this environment.

Design and principle of operation of a household fecal pump

Mainly used in everyday life is a submersible fecal pump. Unlike stationary surface and semi-submersible installations, this device is completely immersed in the working environment, which ensures low noise operation and fairly low energy consumption and power. But the most important characteristic of a submersible system is its compactness. It does not require powerful engine, which is necessary for surface equipment to suck out and lift a relatively liquid medium upward, and does not need a long shaft, like a semi-submersible one. Fecal pump, submersible, with a solids grinder, the most convenient equipment for everyday use.

The body itself is installed on the floor of the cesspool and fixed there, either rigidly, using fasteners, or simply using a heavy cast base with holes for sucking in liquid waste.

The principle of operation of a fecal pump with a grinder is quite simple; a cutter knife is installed in the area of the working impeller, which during operation grinds liquid waste, simultaneously crushing solid inclusions. This principle is somewhat reminiscent of the operation of a meat grinder, but instead of an Archimedes spiral, an impeller is used. Through the inlet, it draws liquid waste into the snail, the knife grinds it, after which the waste comes out through the outlet pipe.

The design of the fecal pump itself with a grinder for the toilet, a submersible system of a conventional vertical design, with a sealed power cable input, from top to bottom, an electric motor, an oil chamber, it is simply necessary to ensure the tightness of the housing, lubricate the shaft bearings and reduce the heating of the device. Next is an impeller mounted on the shaft, installed in a casing - a volute. The chopper blade itself is installed behind the impeller, and sometimes directly on it. This could be a cutter knife, a knife with blades with sharp edges, or other types of cutting-type shredders.

Such systems are used both in toilets, a fecal pump for a toilet with a grinder is sometimes extremely necessary for a summer house or a private house, with installation in the sewer behind the toilet, and for cesspools, depending on the need for the direction of sewage.

Characteristics necessary for choosing a submersible fecal pump with a grinder

When purchasing a submersible fecal pump with a grinder, you need to pay attention to the following characteristics:

Power, energy characteristics and energy consumption of pumping equipment. First of all, the supply voltage, as a rule, a household fecal pump uses a 220V electrical network for power supply, but there are also more powerful systems powered by a three-phase network; the engine power should be calculated based on the volume of pumped liquid waste, usually for country house 500-1000 W is enough, more powerful equipment is required for the home.
Performance, a very important characteristic, shows how much liquid waste the equipment can pump over a certain period of time.
The pressure created, the ability of the engine to lift up and move liquid waste along the horizontal section of the hose.

When choosing a submersible fecal pump with a grinder, you should pay attention to models with a metal body; this material is more durable than plastic and can withstand heavy loads, although modern plastics are not much worse in this regard, and are even better in terms of corrosion protection. Products made from ordinary steel quickly corrode, the waste environment is very aggressive, and the metal oxidizes very quickly. Therefore, it is worth paying attention to products made of cast iron or light metal alloys.

When purchasing a fecal pump with a grinder for a cesspool, pay attention to products from well-known manufacturers, this will save you from a number of problems with the equipment in the future, for example:

purchasing spare parts, parts and chopper knives from a certified device, spare parts and components are quite affordable, which cannot be said about the products of our Chinese friends;
compliance with equipment passport data, availability warranty period and high-quality execution;
durability and efficient work equipment, Chinese fakes are usually short-lived, and also do not deliver the promised power and efficiency.

A submersible fecal pump with a grinder is not a luxury, it is a household necessity. Its presence eliminates a number of not so pleasant moments associated with sewerage.

Progressive hydraulic devices, which include a fecal pump with a grinder, help ensure its uninterrupted functioning. It has several versions suitable for specific operating conditions. What it is and how to choose the right unit is in our article.

Methods of use

The device has multi-purpose use in domestic and industrial conditions. It is installed for seasonal pumping in warm time years in the following cases:

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

The built-in mechanism is capable of grinding not only fibrous structures that fall into the sewer, but also perform other work for the garden. Knives can easily chop up organic elements found in water:

grass or fallen leaves from trees;
seaweed;
particles of household waste, etc.

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

Due to the fact that a fecal pump with a grinder for cesspools literally cuts the garbage it encounters into millimeter-sized fragments, the risk of jamming is reduced. This feature allows the devices to be used in transporting the following liquids:

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

A variety of sewage pumps with grinder are needed for places where sewer system uncontrolled use by a large number of users, in particular, we are talking about public toilets.

Foreign solids can also get into pipes in catering establishments, campsites or factories. Water is pumped out with units of this type from natural reservoirs for their partial drainage or for liquid selection. Silt or algae can enter inside. Additional cutting is not necessary in systems with channels with an internal diameter of 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 design. It has several options:

the blades of the screw impeller, which has a conical shape, are sharpened on the outside;
sharpened blades pass closely along the polished end of the output cylinder, providing a scissor effect;
a pair of knives is located coaxially with the diameter, processing incoming waste;
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 products are designed for 380 V.
Frame. Different copies are made of different materials.
Fence part. Allows fluid to flow without blocking the inlet.
Outlet pipe. It allows connection to a pipeline for further transportation of liquid.

An important feature of a fecal pump with a grinder for cesspools is the use of corrosion-resistant housing and working units. external influence materials. They must withstand mechanical and hydraulic loads, and also not be subject to destruction from chemicals. A durable body must not be destroyed by fine sand acting as an abrasive.

The material for the body is:

Stainless steel - this material is practically not subject to corrosion.
Cast iron - powerful body withstands significant mechanical load.
Plastic - used in budget models, resistant to chemicals.

Knives are made only from stainless high-alloy 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 he also copes with other tasks 100%. We are talking about the following potential:

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

If flooding occurs regularly, you can make pits or storm drains in the basement or basement to place the unit. And if you choose equipment with a float, you don’t even have to pull it out - it will start working as the pit is filled.

It is convenient to use a pumping unit for cleaning drainage holes or collectors. It is also convenient to use it for pumping out the chambers of a septic tank in order to transfer liquid to the filtration field.
If there is a river or lake nearby, you can use fecal equipment with a grinder to collect water for irrigation or other technical needs. Strong steel knives are capable of cutting through any solid inclusions, not counting mud, algae and branches, so there will be an abundance of water cleared of foreign objects in the area.

Types of models

Each fecal pump with grinder for cesspools belongs to one of three large groups. The main difference between them is the installation method:

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

Immersion models are the most popular in households

Surface fecal pumps with grinder. They are based on land, and the intake liquid is supplied through a special pipe or hose with a diameter of more than 60 mm. The 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 installed outside the house

Semi-submersible vehicles. Rare examples have a shredder, since the maximum diameter of possible contaminant particles is limited to 15 mm.

In addition to devices for domestic needs, industrial installations are used. They are installed in institutions, enterprises and organizations.

When choosing a product for pumping liquid from the kitchen or from dishwasher, it is necessary to select a specimen capable of transporting hot liquid with temperatures up to 80-90°C.

Type of operation

Installation depends on the method of use. In some households, pumping is used regularly, sometimes from time to time.

In the case of stationary operation, it would be appropriate to use a submersible fecal pump with a grinder or use a semi-submersible unit. Dismantling for them will be necessary only for the period of prevention 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 outlets from the bathtub, kitchen, bathhouse and other places are connected to such a tank.

It will be necessary to configure the system for pumping depending on the degree of filling of the well. After removing waste, it is supposed to turn off the automation 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. Additionally, a pulling cable is attached to the device.

Vertical posts provide the desired working position. Moving along them, the device descends to the very bottom of the pit. After work, take out the unit, clean 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 grinder for cesspools or pits, you should focus on certain parameters. Among them:

Power and voltage

Most of the modern household equipment operates from a standard 220V power supply. Power determines its 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 sewage of a small country house, which can also be used for pumping water from the basement or draining, then equipment with a power of 500 W will do just fine. And if you need equipment that will work constantly and “serve” a family of several people, the optimal power will be 1-1.5 kW.

Performance

This is the volume of liquid pumped per unit of time. For all types of suction equipment, this indicator 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 will pump 650-700 liters. This means that even with a large volume it will not take much time to work.

Column height

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

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

What is the body made of?

Metal is an absolute priority, since 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 waste water- too aggressive chemical composition so that the steel body can 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 if it receives an accentuated blow.

The presence of a float (water level sensor)

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

Immersion depth

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

Solids size

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. The knives are capable of crushing even stones.

Working environment temperature

Depending on the environment in which - hot or cold - the drainage device is planned to be used, the operating temperature is also selected. Cold indicator - up to 35°C. Hot - up to 90°C.

Rating of the best models of fecal pumps with a grinder

Let's look at several popular, in-demand devices that have proven themselves in the domestic hydraulic pump market:

Gilex 150/6

Russian manufacturers offer a budget model for 3,000 rubles. It refers to household type and can be used for pumping out sewerage in the house. The power is 0.4 kW with a maximum pressure of 6 m. It operates from a household power supply of 220 V and is capable of flowing 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 corrosive processes. The power is 900 W, and the throughput reaches 15 m 3 / hour. Starts from a voltage of 220 V. Operates at a depth of up to 10 m.

ESPA Draincor 180

Spanish installation, providing excellent value for money among analogues. It withstands various environments and operates with minimal noise levels. The body of the device is cast iron. Power is 1.7 kW. The pressure reaches 12.5 m. Capable of withstanding voltage drops of 220±10% V.

For a permanent connection in the toilet, the Grundfos Sololift2 line is used. It starts and stops automatically after liquid enters the working cavity. The installation is installed directly behind the toilet.

VIDEO: Grundfos SEG sewage pump with cutting mechanism

Private households for the most part do not have a connection to the central sewerage system. IN sewage pit waste from toilets, kitchens, and bathrooms enters the area. The volume of the cesspool quickly increases and constant cleaning is required to prevent waste from flooding the area.

Sewage pump with grinder for – good decision for a private house or cottage where it is not possible to connect to a central pipe or the location of the house does not allow wastewater to be discharged away from the site. You have to periodically pump out the contents using a pump and hire a sewer truck.

Why do you need a fecal pump?

The scope of application of fecal pumps is quite extensive:

for pumping street contents country toilet into the sump, located closer to the street, for ease of removal;
for pumping waste and fecal water into a special machine;
in places public use– beaches, cafes, hotels where there are kitchens and large food waste ends up in the drain;
for cleaning reservoirs where there is a high probability of large soft objects getting in;
draining areas or basements from wastewater after rain or snow;
for pumping out city sewerage in case of blockage.

This is just a small list of capabilities that a submersible fecal pump can perform.

Pump operating principle

Sewage pumps with a grinder have different operating principles depending on the modification:

Submersible units protected by a waterproof case. They are assumed to be completely immersed in the working fluid. There is a sensor to monitor the wastewater level. The cutting mechanism processes and crushes large particles with a diameter of up to 5 cm into smaller ones.
Semi-submersible mechanisms assume the location of the motor above the wastewater. There is also a sensor that prevents the engine from touching the working fluid. The motor is not protected.
Surface fecal pumps with a cutting mechanism, the working fluid is pumped out through a special hose, which is inserted into a sump or cesspool.

Important! The most versatile and practical device is a surface pump. It can be used in all situations on the territory of a residential building or cottage, be it pumping dirty water, fecal matter from a toilet, or draining an outdoor pool. Such models are least susceptible to contamination, so maintenance of the device will be carried out rarely.

Toilet pump device

Fecal pump made of corrosion-resistant materials. This is especially true for submersible models, which always operate in chemically aggressive liquids. Most often these are cast iron and stainless steel.

The pump has an oil chamber that protects the main working units from overheating. The oil does not need to be changed during operation - it is designed for its entire service life.

There is a cutting wheel with sharp knives for grinding large particles. Surface models have a pipe through which liquids are sucked in.

The main design detail is an electric motor. The devices are equipped mesh with a certain cell size so that objects larger than expected cannot get into the mechanism.

Surface pumps

External pumping equipment is capable of crushing not only soft objects, but also wood, plastic, and glass that have gotten inside. The more powerful ones also crush stones. The devices differ:

power;
shape;
sizes.

The model can be selected based on the purpose for which it is purchased. The use of surface equipment is convenient because it can be moved if necessary and install in different places.

Submersible pumps

The main purpose of submersible sewage pumps is to clean septic tanks. Most of these models are automated and can be customized independent switching on according to a specific schedule.

If this is a pump for fecal matter in a public place, then it will need to be turned on several times a day so that the pit does not overflow and the smell does not penetrate into the room. Replaceable carbon filters are used to neutralize odors.

Sometimes submersible models with a chopper are used in agriculture. It is used to prepare raw materials for compost. A manure pump with a grinding mechanism crushes cattle feces along with straw and other vegetation, then pumps it into piles where the compost heap is located and organic fertilizer matures.

For industrial use, powerful models are needed, for example, mobile pumping station, which runs on diesel fuel. The manure pump is installed on a vehicle, most often a tractor. Such equipment makes people’s work easier and speeds up the process of preparing fertilizer.

Important! Submersible mechanisms are more complex in design and require careful installation according to the manufacturer's instructions.

Which pump is more convenient in everyday life?

For domestic use, units are used that operate from a standard 220 V power supply. If there is only one phase on the site, then you can choose a model for such a case. A household fecal pump can operate from either a two-phase or three-phase network.

In order for the pump to cope with all tasks, the diameter of the mesh must be at least 3.5 cm. Larger is better, since children can throw anything into anything - clothes, toys.

For household use you can choose any model– submersible, semi-submersible or surface. It depends on where exactly the device will be used:

if only for the toilet, choose a submersible model;
if you plan to change the place - then superficial;
if the plot or basement often flooded and the main problem is wastewater, then semi-submersible.

Judging by consumer reviews, they most appreciated surface and submersible models, which require less repair and are more versatile.

If the kitchen and toilet have the same drain, then you need to purchase a submersible model, because:

the unit will not freeze while in the working fluid if you plan to operate it all year round;
fecal pump with grinder for cesspools can be raised to the surface if necessary and inspect;
the minimum power is enough to periodically turn on and clean the septic tank, which saves energy.

Sewage water equipment with grinder can also be used to pump liquid into compost heap, where you can prepare by fermentation organic fertilizer for the garden. To do this, just add a concentrate of live bacteria. Liquids with chemical additives such as detergents and powders. Therefore, only fecal waste should be used.

Installation of a cesspool pump

For stationary use, the unit must be lowered into the pit along guides. It’s good if you plan to use the device when the pit is not yet filled, since it will require connecting the pipe to the outlet pipe, which is easier to do in dry mode. First, the submersible equipment is attached to, then lowered to the bottom of the pit, where the pipe connects to the pipe. The device is fixed by its own gravity - this is facilitated by the heavy cast iron body.

Surface models for pumping cesspools are not used in winter time, since the liquid freezes easily and leads to equipment failure. Such units are useful for summer cottages in the spring-summer period, when the temperature outside is above zero.

There is an option to connect the pump directly to the toilet. The equipment will crush the waste and send it to the pit. If the pump has a cutting mechanism, then a large diameter pipe will not be needed.

For connections between pump and plumbing equipment an adapter is needed. This model can be hidden so that it does not spoil the room or toilet. The temperature of the liquid should not be higher than 40 degrees.

Several types of plumbing equipment can be connected to one unit:

toilet;
bidet.

For hot drains, you need a different model that can withstand temperature up to 95 degrees. If planned permanent residence, then it is recommended to immediately purchase a universal device to which you can connect a dishwasher and washing machine. It will cost more, but it will be convenient to use.

The cost of equipment starts from 17,000 rubles.

To choose the right equipment for home use, you need to know several important points:

at what depth the pump will operate;
estimated distance from the pump to the waste storage area;
approximate volume of liquid;
what size will the solid impurities be;
what is the diameter of the pipe leaving the equipment.

You can determine the required working depth using the formula: pit depth + (distance to storage location divided by 10). Example: 7 meters is the depth of the septic tank. The distance of 20 meters to the sump, divided by 10, will be equal to 2. And 7 + 2 = 9 m. That is, you need a unit that will operate from a depth of 9 meters. Accordingly, it is necessary select device power with such performance characteristics.

Important! Pumps for pumping out cesspools help make life in a private home more comfortable, so it’s worth investing in purchasing a suitable model.

A fecal pump is an expensive, but practical and reliable device. For correct operation, you must follow the installation rules described in the operating instructions. At correct connection and meeting operating conditions, you can count on a long service life without the need for repairs.
