Fecal pumping equipment is designed to pump clean or contaminated fluid with organic and fibrous inclusions. In private households and summer cottages it is used for pumping cesspools or septic tanks, watering the garden or drying the pool for the winter, eliminating floods in basements, much less often these devices are used to pump water from the well.
Properly selected equipment can solve many problems associated with pumping water on the farm. And the fecal pump with a cutting mechanism in this case is a universal model.
Appointment
Pumping equipment, equipped with a cutting mechanism, allows you to remove feces from rooms that are located below the level of sewer pipelines, most efficiently. Also, the presence of a fecal pump when installing additional equipment does not require reconstruction of the premises.
A fecal pump with a cutting mechanism, ready to be connected, allows you to place kitchen rooms and bathrooms below the sewer level, as well as in remote places where it is not practical or impossible to install a gravity sewer system. This equipment is intended exclusively for domestic use, and its installation and operation have certain requirements.
Areas of use
- Installation in the sewer system of industrial facilities of the food and processing industry, into the drains of which organic waste may be released.
- A fecal pump with a grinder can be used to clean the sewage system from silt deposits.
- Pumping water from a storm system, a drainage well and other water intake facilities.
- Cleaning of cesspools and septic tanks.
- Fecal cutting pumps are also mounted for the purpose of pumping sewage from sanitary equipment (washing machine, dishwasher, sink, toilet, etc.) located below the sewer system.
Types and Features
Pumps for sewer systems differ structurally depending on the purpose. Let's consider them in more detail.
Pumps for bathrooms
The pump for fecal sewage with a cutting mechanism in the bathrooms is mounted directly behind the toilet. This connection method allows you to pump fluid through pipelines with a diameter of 30-35 mm. In most cases, such models are equipped with an automatic switching mechanism and are launched at each discharge.
A fecal pump with a grinder copes with organic and fiber inclusions, but solid waste, for example, sand or stones, can lead to its breakdown.
When choosing, it is desirable to pay attention to equipment with the ability to connect several household appliances at the same time (bath, toilet, bidet, shower), while the pump should have a lowered inlet.
Pumping drains from dishwashers or sinks
Fecal cutting pumps for pumping wastewater from dishwashers or sinks are designed to work with hot liquids with a temperature of 80-90 ° C. Such equipment requires annual preventative cleaning due to the fact that fat deposits settle on its surface. In active use, more frequent cleaning is required.
Load, semi-submersible and immersion devices
These pumps can be distinguished as a separate group, they are designed for use in private homes, in the country, as well as in enterprises for pumping effluents from reservoirs, cesspools, septic tanks. Fecal submersible pumps with a cutting mechanism are characterized not only by excellent technical indicators, but also by large flow channels, therefore they can easily cope with large volumes of liquid and rather large organic impurities.

The pressure of the pumping equipment indicates how high the pumped liquid can rise. This is especially important if the fecal pump with a cutting mechanism must pump a large volume of liquid, and sewer pipelines are located deep underground. The standard operating temperature of this equipment is +40 ° C. This is the most optimal temperature at which a fecal pump with a cutting mechanism will work properly. A short temperature increase to +60 ° C is possible, but this rarely happens.
Regarding the material from which the cutting mechanism and the body are made, it is, as a rule, stainless steel and cast iron. Steel parts are lightweight, but these structures are more susceptible to corrosion. Devices made of cast iron have high corrosion resistance, but they are quite susceptible to temperature extremes.
Selection tips
Currently, the pumping equipment market is overflowing, which significantly complicates the choice of the most optimal model, especially if you do not have an idea about the main characteristics that you need to pay attention to:
- The distance from the drain to the fence.
- If the fecal submersible pump with a grinder is not additionally equipped with adapters, then the diameter of its nozzles must coincide with the diameter of the sewer pipe.
- Desired performance.
- Depth of immersion of the pump unit.
- Duration and frequency of operation.
When choosing a fecal submersible pump with a grinder, equipment for a bathroom or for pumping wastewater, the following basic parameters must be taken into account:
- Engine power is the most important indicator, on which the service life and performance largely depend. After all, the greater the power of the unit, the greater the cost of electricity.
- Diameter of possible inclusions and purity of pumped effluents.
All of the above requirements will allow you to choose the most optimal pumping equipment for your sewer system, which will ensure its smooth operation.
