Sump pump with cesspool grinder: design and function

The scope of use of a fecal pump in a suburban economy is quite extensive

Practical use area

The area of ​​practical application of fecal pumps with a cesspool grinder is quite extensive. A key feature of the unit, in addition to pumping, is the crushing of small soft objects that enter the sewer. Enterprises that use the production and sale of foodstuffs conceived have to deal with a situation of a clogged sewage system. It is in such industries that it makes sense to install a fecal pump with a grinder.

The versatility of the application makes such a device indispensable in organizing independent sewerage systems for summer cottages and for maintaining household plots. The unit can be used for pumping sewage masses from sedimentation tanks and cesspools, draining and cleaning small reservoirs on the site, eliminating the consequences of heavy rainfall and melting snow.

Shredding waste is done with a built-in knife

A generalized list of areas where it will be necessary to use a sewage pump for cesspools:

• removal of the contents of cesspools and sedimentation tanks;
• cleaning of artificial and natural reservoirs;
• drainage of basements, wells, cellars from flooding with sewage or melt water;
• watering the backyard of a residential building (rarely);
• pumping out sewer masses into the riser, in the absence of a proper slope of sewer pipes;
• use in the industries of food production and cooking, where there is a high probability of getting into the sewage system of household and organic waste;
• application in the sewerage system of organizations of mass leisure, recreation and sports (hotels, canteens, cafes, stadiums).

Modifications and functional specifics of fecal pumps for wastewater pumping

There are three main modifications of fecal pumps:

• submersible pump;
• semi-submersible unit;
• surface apparatus.

Submersible fecal pump

Submersible models involve lowering the pumping unit into a tank or cesspool with sewage. To determine the depth of the liquid, the pump is equipped with a float. Thanks to the submersible pump, you can handle the pumping of water from basements, clogged wells, sedimentation tanks or trenches. The technical components and the engine of such a device are protected by a reliable sealed housing made of durable material. It can be a steel, cast iron or polymer version of the body. The latter is used in models with low power. The main requirement is high resistance to corrosion and active chemical reactions occurring in the sewage masses.

Submersible pumps are equipped with floats, which are necessary for determining the liquid level

Useful advice! If you decide to change the place of use of the submersible fecal pump or it fails, it must be thoroughly cleaned from contamination.

Spending most of the time in a country house, you should definitely get a submersible fecal pump with a grinder for a summer residence. The price of such a model is quite acceptable.

Semi-submersible fecal pump

In semi-submersible pumping units, the engine is located above the surface of the contents of the cesspools, and the pump is lowered into the liquid mass. This position of the pump is held by a float that prevents the engine from touching the sewage.

The peculiarity of semi-submersible models is that the pump motor remains above the surface of the liquid mass

The pump installation is not equipped with a protective casing due to the lack of interaction with a chemically active working fluid. Such a model of a fecal pump requires a special stationary installation inside the tank, operates noisily, is not equipped with a grinder and is rarely used in domestic conditions to pump sewage from cesspools.

Surface or external fecal pump

External fecal pumps are installed next to the storage tank and the process of pumping out the contents of the pits is due to the immersion in the liquid of the suction pipe. Pumps of this type are transportable, they are installed immediately before pumping out waste from the pit. Surface models of pumps are little susceptible to contamination, they can easily be relocated to other areas of work, whether it is pumping out basements or providing technical water for irrigation in the country.

Surface fecal pumps are transportable, so they can be used to pump out several cesspools in turn

Useful advice! If the surface pump operates at sub-zero temperatures, it must be insulated. Otherwise, there is a high risk of freezing of the liquid inside the pump, which will damage the device.

For country cottages and private houses with an individual sewage system, it makes sense to use a fecal pump with a grinder. This will eliminate the constant monitoring of the entry into the sewer of objects larger in volume than prescribed in the equipment operating instructions.

To prevent clogging of the sewage system in houses where the required drainage slope is violated or there is a high probability of non-standard inclusions entering the drain, a fecal pump with a toilet grinder is used.Such structures are mounted directly behind the toilet, they are equipped with an automated turn-on function at the next actuation of the cistern and can combine several connections from other plumbing fixtures. By using a toilet shredder pump, you can forget about emergency sewer services forever.

Sump cesspool pump with shredder - model selection

A submersible fecal pump with a grinder is used to crush objects that have fallen into the settling pits when pumping out their contents. The immersion depth of the unit reaches 10 meters. The prevention of dry running of the pump is achieved with an integrated float switch. The pump automatically turns on when the critical level of fecal matter in the cesspool is reached and turns off when the level of drains decreases.

Unlike semi-submersible models, submersible pumps are equipped with a protective cover

The submersible fecal pumping unit consists of the following elements:

1. Housing (made of corrosion-resistant material).
2. Rotor.
3. Stator.
4. Elasticated cuffs.
5. Sleeve (made of stainless steel).
6. Oil chamber (prevents overheating of units).
7. Rubber gaskets ..
8. Working cycle wheel (with cutting edges for chopping).
9. Volute cover (equipped with cutting links).
10. Branch pipe with removable connector.
11. Specially designed mesh (for more convenient transportation).

When choosing a submersible fecal pump model, consider the following indicators:

• frequency of operation;
• the depth of the container;
• distance to the intended drain;
• unit power;
• diameter of the working branch pipe;
• permissible sizes of processed inclusions.

Useful advice! When purchasing a submersible fecal pump, make preference in favor of trusted manufacturers. They will provide warranty periods of operation and quick replacement of necessary parts in case of failure.

The installation of sewage pumps is carried out in accordance with the operating manual, the components and parts are attached to the set with the main unit.

When choosing a fecal pump, you should pay attention to its technical characteristics.

Preparatory work before pumping out

Having familiarized yourself with the advantages and principles of operation of fecal pumping equipment, you can make a choice that is acceptable for a particular system. If an automatic mode of draining sewage from the pit is planned, you will need a submersible model of a fecal pump. The submersible unit will cope with its function when the distance to the bottom of the cesspool exceeds three meters or septic tank located in such a way that it is impossible to approach it with a sewer tank.

If the pumping of sewage water into a sewer or a special sump will occur from time to time, a surface installation will be appropriate here. After cleaning, the unit can be detached and used for other purposes without preliminary cleaning.

Pump layout inside septic tank or cesspool

To determine the required pressure, it is necessary to add the horizontal transportation distance to the number of vertical meters (add one meter for 10 meters). For example, if it is necessary to raise the contaminated masses to a height of 4 m and pump them 20 m horizontally, then the required pump head should be 7 m (4 + 2 + 1 stock).

Useful advice! Before you start cleaning the drain pit, it is necessary to dilute the thick masses of the sewer with a little water. The water should cover the sewage by about 5-7 cm. After that, bacterial agents are poured into the pit to liquefy the fecal masses.

For the purification of fecal effluents, it is recommended to systematically use special biological products, under the influence of which the unpleasant odor is neutralized and the feces decompose.

Using in your farm a fecal pump for cesspools with a grinder, you can once and for all refuse the services of sewers and independently plan pumping out wastewater as needed.
