Equipment for autonomous sewage should serve for a long time, work without fail and not upset with breakdowns. How to decide on a model and buy the most suitable fecal pump with a grinder? Indeed, the list of duties of this technique includes not only pumping aggressive liquids, but also the processing of large organic particles.
To the adherents of suburban life, we will tell in detail all about the design features and guidelines for the competent choice of a fecal pump. With our help, you can easily find and purchase the optimal model with the required performance and excellent technical characteristics.
In the article presented to your attention, types of fecal pumps are described in detail, their differences in device and operation are described. For potential buyers the rating of models demanded by the market is given. Information is backed up by photo images and video instructions.
Fecal Pump Information
Several types of such technological equipment have been developed and are being produced on the consumer market by industrial production.
In particular, future users are offered:
- submersible devices;
- semisubmersible devices;
- devices of external action.
Each of the fecal models differs in technical capabilities, is intended for specific pumping conditions. In order to select equipment in essence, it is recommended to obtain information on the degree of contamination of the working environment, as well as information on the conditions under which the pump will be operated.
Fecal submersible pumps are widely used in various sectors of the economy. The same devices are actively used by owners of private suburban real estate.
Immersed equipment is arranged in the form of a hermetically sealed structure, which, together with an electric motor, is permissible to immerse in the thickness of a liquid medium. Semi-submersible fecal apparatuses are products in which only the pump part is placed in a liquid.
Finally, external fecal pumps, endowed with a grinder, do not directly contact the liquid medium. Contact is made through a soft sleeve or a rigid pipe.

Sewage pump - equipment for the maintenance of the sewer system, designed to stimulate the movement of waste mass. The chopper mounted in its receiving part "grinds" organic impurities to facilitate pumping and moving
Fecal pumps are used both for servicing individual facilities and for pumping effluents from a group of houses
Fecal pumps are used if, for technical or structural reasons, spontaneous movement of effluents is impossible or difficult. For example, for periodic pumping of a cesspool or permanent work in a collector well
Fecal pumps are installed on different parts of the sewer system. They are needed when installing bathrooms in the basement and basement rooms connected to the manifold pipe laid above
Pumps for periodically pumping wastewater from cesspools or drainage pits, sewage wells are used as wastewater accumulates. For pumping, the equipment is immersed in a pit or well.
Pumps for independent sewage are selected, based on the tasks assigned to them, the area of the upcoming operation and power
Submersible fecal pumps designed for periodic pumping are equipped with floats - devices that turn off the device when the minimum level in the pit or well is reached
For the right choice of a fecal pump, it is necessary to take into account the whole range of characteristics: power consumption, feed height, capacity, maximum diameter of the crushed inclusions and other data

Submersible float models
Immersion devices are designed for operation in a liquid medium of varying degrees of contamination. The design of such devices is made so that the equipment can be lowered to a certain depth (usually no deeper than 10 m) and the liquid pumped out directly from the depth.
Pumping equipment designed for pumping feces is no less successfully used for other purposes. For example, to drain the construction site after rains or basements of buildings flooded by showers
Submersible fecal pump works with a liquid medium of a certain temperature range (from + 1 to + 40 ° C). This type of equipment is designed to transport various types of fluid. But it is always necessary to comply with the technical specifications of the operating parameters of the pump.
For example, immersion modifications with grinders successfully pump:
- liquid with a high degree of viscosity;
- liquids with a high content of large and solid particles;
- sewage drains and contents of cesspools;
- the contents of septic tanks and household cleaners,
- water from basements, stormwater, various reservoirs.
Each model of a submersible fecal pump is equipped with a control float mechanism. The purpose of this mechanism is to protect equipment from inadvertent dry running.
That is, the equipment will not be included in the work if the work area is not filled with the pumped medium. As the working chamber is filled with liquid, the control float moves to a position that allows switching on, and the apparatus starts.
This is the design of the submersible type fecal pump in the drawing. In the suction area, a shredder is usually contained on the shaft, due to which the pump cuts and pumps out associated waste (+) with water
In addition to automatic on / off control, depending on the presence / absence of the pumped medium, submersible models have additional protection, so there is no doubt about the reliability of fecal pumps. This is the most optimal equipment, which is recommended for use in private households.

External fecal devices
Equipment for external installation (surface pumps for pumping faeces) is most often used in industrial production facilities. For private ownership, this type of fecal equipment with a grinder seems to be not a very suitable choice. Meanwhile, there are developments specifically for the household.
External devices pump sewage from the depth of the sewer pit or well, while being above the level of the septic tank.
In order to raise a viscous fluid from a depth of several meters, the apparatus must have a powerful electric motor and an effective design in general. Therefore, external systems are usually bulky, endowed with a large-sized electric motor.
Cantilever centrifugal pumps are used to service a local sewer facility to which several households or a settlement are connected
Stationary installation is traditionally inherent in external fecal pumps. At the same time, it is necessary to place the equipment in such conditions that during further operation a normal ambient temperature and protection from precipitation are ensured.
Equipment in this design emits an increased noise level during operation. Before starting the pumping of effluents or feces, the pump scroll will have to be filled with “starting” liquid. Without preliminary filling of the cochlea with water, rare models of external fecal pumps with a grinder are capable of independently capturing liquid from a lower level.
Systems for the internal sewerage of a private house
Household pumping stations for shredding and pumping feces have some relation to external fecal equipment. Especially those that are installed directly inside a private house. This type of equipment is used as the organization of forced sewage, when the feces are processed (crushed) and thrown into a septic tank using a pump.
The design of the fecal pump, designed for installation in the internal sewage system of a private house. Using such equipment, a system is created for the forced discharge of feces into the waste collection
The design of such equipment is intended for installation on the line of feces exit directly from the toilet. The device is a rectangular product with inlet and outlet nozzles. Inside is a miniature pump, powered from a 220 volt network. Also, the device is equipped with a filter element and grinder mechanics.
There are various models of domestic fecal pumps. The difference between the models is in performance, pressure, and also in what temperature conditions the device is designed (up to + 40 ºС or up to + 90 ºС). As an example of such equipment, we can mention the Sanitop Silence model of the well-known company SFA.
Semi-submersible pumping equipment
Along with the first and second types of fecal pumps, there is an intermediate version - semi-submersible devices. This type of equipment also applies to permanently mounted devices, and the installation of semi-immersed systems requires a special approach.
Such designs conditionally consist of two modules - a driver and a pump. The driver (electric motor), usually installed as an external module, at a level above the pumped waste. The pump module is lowered to the lower level and immersed in a liquid medium. The electric motor is connected to the pump through a flexible shaft.
Another type of fecal pumping equipment is a semi-submersible system. Refers to stationary type devices and is mainly used for the needs of the industrial and economic sector
Stationary semi-submersible systems have been successfully used as part of farms, at centralized sewage stations, where continuous pumping of waste and effluent is required. However, such equipment is unlikely to be suitable for use in the private sector.
For summer residents and owners of small country houses with a small number of residents, we recommend that you familiarize yourself with the rules for choosing fecal pumps for a summer residence. In the article we proposed, the technical capabilities of popular models are thoroughly analyzed.
Fecal Pump Shredders
Mechanical working elements - grinders - are an integral attribute of a fecal pump. The purpose of these elements is obvious: cutting, crumbling, separation into small parts of large and dense contents, which enters the pump along with the pumped liquid medium.
Different models of pumps are equipped with various forms of grinders. Each manufacturer tries to achieve maximum effect. However, practice shows that changing the grinder configuration does not have a significant effect on the process. All shredders cope with the task quite successfully - they provide easy access to the pumped medium.
Typically, pumps are shredders made by type:
- impellers with knife blades;
- cylindrical scissor knives;
- cruciform cleaver;
- cutter type "meat grinder";
- lamellar incisors.
Each type of cutter in terms of effectiveness is practically no different from all the others. Another thing is the durability of the element. There is already a direct dependence on the steel grade.
It looks like one of the design options for the grinder of the fecal pump. The so-called "meat grinder" knife cuts large debris into small fractions up to 15 mm in size
Of the latest developments, the German design of the HOMA A-series submersible fecal pump, which uses an innovative grinder solution, is attracting attention.
Equipment performance
Also for the future owner, the parameters are important:
- power (for domestic use 0.5 - 1.5 kW);
- productivity (150 - 600 l / min);
- liquid column height - head (10-20 m);
- working fluid temperature (+ 1 ... +40 ºС);
- temperature of the working environment (+ 1 ... + 40 ºС);
- the degree of density of the pumped medium (up to 1200 kg / m3);
- level of acidity of the working medium (Ph - not higher than 10).
Work with pumping equipment should take into account the indicated parameters, in addition, for each individual model, the marked indicators can be expressed by specific values that cannot be exceeded.
Review of the best brands
The modern market opens up wide horizons for the selection of fecal pumps equipped with grinders. Italian, German, Spanish and other equipment is offered to customers, and each manufacturer puts up an impressive lineup for sale.
Imported products, present in large quantities on the modern market. The main suppliers of fecal pumps are German, Italian, Spanish companies

This is how the rating of the best pumping equipment from the group of fecal systems looks like. Of course, this list should be taken only conditionally. The range of pumping equipment is very large, and only five models are not able to show the situation completely. But in the case of choosing a pump for everyday life, it is quite logical to focus on the indicated list.
Overview of the technical characteristics of the pump from a Polish manufacturer:
