How to choose a fecal pump
The fecal pump serves to pump the liquid with an abundance of solid waste that can not be pumped to a simple pump, usually solid wastes are contained in septic tanks, so if there is a central sewage system, it is difficult to attach a gravity pipe to itand with the correct angle of inclination, therefore, usually used in the area of the container in which solid wastes are collected, and a fecal pump is installed in it. After that, liquid from this container enters the central sewage system.
Let's look at the classification of faecal pumps and determine the differences between them.
Submersible faecal pump and its characteristic
Submersible faecal pump
Submersible pump type is mainly used for dehumidification of basements that have been flooded, in addition to watering various cultivation areas and pumping water from septic tanks.
Installation of submerged pump
It should be noted that there are a huge number of submersible pumps and, accordingly, the installation for different brands differs from each other, but the general doubt is there is a pump mounted at the bottom of the well. It must necessarily be below the water level well, and the automatic and floatthe switch enables the pump to operate in an independent mode.
It should be noted that this unit develops power up to 50 kW in relation to liters - this is about 450 liters per hour. The lifting capacity of the pump can reach 25 meters in height, and the pump can handle dirty liquids if their size does not exceed 4 mm, in addition, the pump can be supplemented with a cutting attachment.
Semi-submersible models
Semi-submersible models are excellent at pumping dirty water but with inclusions only up to 20 mm. The difficulty lies in the fact that unlike a submersible pump, it is impossible to add a nozzle to the semisubmersible model, but often it does not need to be used as for domestic needs, and such pumps are bought exclusively for this purpose. They fit just that easily fecalmasses and small debris.
The engine in such models is installed above the water, and the pump itself in water.
Example of a semi-submersible pump
External pump
An external pump is the most accessible type of pump - it does an excellent job of pumping masses with inclusions only up to 5mm. But the main function of this pump is mobility, and not as a non-resource capacity.
Fecal surface pump
This type of pump is usually installed on the edge of a septic tank or pit, and only the hose is immersed in water. With such a pump, it is possible to pump out feces from a long fraction up to 35 mm, in general, it is perfect for pumping water from a septic tank.

Drainage pumps for slightly dirty liquids
Drainage pumps are mainly able to pump slightly contaminated liquids. Basically these pumps clean basins or pump groundwater out of the cellar, and can also be used for pumping water from tanks and so on. By the way, most of these pumps, can also freely pump out contaminants with small fractions, and a special grid will not allow swallowing solid and large objects, and as a consequence, the engine is overheated.

Pump selection: tips
Advice on choosing a pump .
- If only the numbers are indicated on the pump labeling - this means that the pump can only pump clean liquids with inclusions up to 5 mm.
- If you see the letter F on the pump, it means that the pump can pump even heavily soiled liquids up to 30 mm.
- Well, if you need a pump capable of grinding large fractions, then look for the letter H on the label.
