- Reliable fecal pump for pumping sewage is chosen based on the design of the local system. A feature of all devices for pumping waste products is to remove lumps of dirt without clogging the working chamber.
Choosing the right pump
While equipping the sewage system, it is necessary to remember about the inevitability of removing accumulated solid waste. To do this, use assenizatorsky machine or clean the tank on their own. Fecal sewage pump - the right solution. It is necessary to select equipment based on technical parameters and working conditions. Fecal pump can be:
- superficial;
- semi-submersible;
- submersible.
In this case, there are several varieties of each type of apparatus from different manufacturers.
By marking, you can determine the purpose of the drainage apparatus. If all marking includes only digital parameters - a drainage pump, it can rock drains with suspended particles less than 5 mm. If the letter F is present, the pump is fecal, copes with the pumping of solid fraction, long fibers. If the letter contains the letter H - the device is stable when working in an aggressive environment. In the correct choice of the fecal pump for pumping out the sewage, the outlet manager will help.
A pump is selected for pumping waste through a long gravity flow system to the receiving sewer of the common sewage system, more often, to pump VOC.
Selection of submersible pumps for pumping waste
Working in an aggressive liquid medium, the device must be sealed and resistant to corrosion. Therefore, the fecal submersible pump is made of resistant materials - cast iron, stainless steel or polymers.

- centrifugal;
- vortex;
- screw.
The most effective and reliable experts believe the centrifugal pump.
The device is equipped with filtering mesh on the suction inlet, non-return valve, automatic activation system at a certain level in the tank. Often the fecal pump is used with a grinder, set on a wide substrate so as not to be sucked into the sludge bottom sediments.
Advantages of submersible devices:
- transfer waste with a solid fraction of 80 mm;
- reliability in operation, not destroyed in a specific environment;
- do not overheat in liquid medium;
- creates pressure up to 30 m;
- pumps with grinders pump waste in the pipe with a section of 50 mm, saving when constructing a pressure pipe.
Manufacturers of plants are well-known companies.
We give examples of inexpensive fecal pumps, their features. - Caliber SPC-1350 is a budget version of a submersible drainage fecal pump. The device has a chopper, which is able to skip 18 m3 of waste. In this case, the device is able to skip the maximum size of pieces 40 mm. The pump creates a pressure of 12 meters, is convenient for use in local systems. The cost of the device 5-8 thousand rubles is available for people with low incomes.
- Whirlwind FN-750 operates at a depth of 9 meters. A pressure of 13 meters allows you to raise waste from a low level. The pump does not have a chopper, but there is a float start system. The device is capable of passing solid waste up to 42 mm in size. The device has overheating protection. The price of the pump is 6-7 thousand rubles.
- The Hungarian device Eipumps can be used in everyday life and for pumping industrial wastewater, depending on the modification. Economical reliable device, not inferior in performance to domestic models, costs from 4 thousand rubles.
- Dzhileks Fekalnik - the installation of the Russian plant is produced in a plastic case or made of stainless steel. The capacity of the fecal pump for cesspools is 9-15 m3, the pressure is 11 meters, which is enough for a local system. Depending on the version of the case, the cost is on average about 5 thousand rubles.
- HeizWRS 25 - pump German development, Chinese production. The device is equipped with a grinder, with a head up to 14 meters it is possible to flow up to 15 m3 / hour. Energy consumption of 0.8 kW, protection against overheating, the execution of cast iron or stainless steel makes it possible to consider the model reliable and economical.

Pumps of the brands Grundfos, Pedrollo, WILO-DRAIN MTC-MTS are expensive high-performance equipment, with automatic switching on and a high degree of protection.

The body is made without sealing, in the rain or without a spray canopy, the engine may become unusable. Attract installations by compactness and mobility. They can be stored in the host unit, setting only at the time of the buildup of the sump. The inlet is equipped with a grid, there is a built-in check valve. The equipment is easy to use, cheaper than immersion systems.
The design of the surface pump does not imply the design of a shredder, permits particles up to 5 mm. The capacity of the installations is lower, but mobility allows the use of apparatuses in various economic activities.
Semi-submersible pumps
A semi-submersible drainage fecal pump combined the advantages of submersible and surface installations. The device is vertical, the engine is on the surface and does not require sealing. Due to the simplified design, the cost of the pump is low. The device works with less efficiency in comparison with the submersible one, only the pump of the brand NCI-F100 can be recommended for a private residence, with a pressure of 8 meters and a power of 0.5 kW.Of all the listed types of faecal pumps for cesspools, submersible ones are more often chosen as more technological and reliable.
