Pump for pumping sewage at home. Household pump for pumping sewerage

It often happens that it is simply impossible to connect to the central sewer. In this situation, homeowners resort to the development of their own sewer system - they dig cesspools, where waste from the kitchen and bathroom will be sent through the pipeline. But sooner or later the pit is filled completely and there is a need for its pumping.

Pump for pumping sewage in the home - an adaptation on which the sanitary condition of a nearby private house depends.

Why is it needed?

Thanks to the pump equipment, in particular the sewage pump , the following tasks are solved:

• Purification of waste water and sludge removal;
• Pumping contaminated water;
• Evacuation of faecal waters;
• Cleaning of sewage systems from dense deposits;
• Liquidation of the contents of cesspools and waste pits, a toilet.

How are pumps for pumping sewage?

The device consists of the following parts:

1. The inlet.

2. Outlet hole.

3. Cutting mechanism. It is intended for grinding all particles and foreign objects that have got into the sewage. As a rule, it is an impeller with a cutting edge.

4. The engine.

The larger the diameter of the inlet and outlet openings, the higher the pump capacity. Wide flow channels allow you to pump a contaminated liquid with foreign particles, the size of which is 1-10 mm.

Pump for pumping sewerage: types and features

Depending on the intended use, all pumps are divided:

• On drainage;
• Fecal (sewer).

The first is designed exclusively for the elimination of contaminated water. If it is a question of evacuation, the best option is to use a fecal pump.

The pump for pumping sewage at home, in turn, happens:

• With a chopper;
• Without a chopper.

The unit with a chopper can pump out cold water (no more than 40 degrees), while a pump without a chopper is only suitable for pumping hot wastewater, the temperature of which can reach 90 degrees Celsius. The equipment equipped with a chopper is in great demand.

By the method of placement, the pump can be:

• Outer. Installation of such equipment is carried out directly at the top of the cesspool. The intake of liquid takes place by immersion in the aqueous medium of special hoses. The chopper is not equipped.

• Submersible. The opposite of the previous subspecies of equipment. It functions after the pump is placed in sewage. Features of the design of this type of pump allow you to install it on the bottom of the cesspool. The body of the device is made of high-quality materials that are not amenable to the harmful effects of corrosion. Several design options are possible depending on the depth of immersion.
• Semi-submersible. Conditionally it is possible to divide into two component parts: the pump part and the part where the engine is located. The first is completely lowered into the water, and the motor is on the surface. The chopper is not equipped.

Pump for sewers and rules for pumping it out

Pump for suction of sewer Water must be equipped with a cutting mechanism-chopper. This is necessary in order that this equipment does not fail and effectively worked when pumping contaminated water, which contains large waste and other debris (exceptions: stone, metal, etc.).

The fecal pump with a shredder is ideally suited for pumping waste water. Has a large diameter of the inlet and outlet holes, which provides a high level of equipment performance. This makes it possible to use a sewage pump in both domestic and industrial conditions. With your hands, you can pump out a filled pit by performing a series of actions:

• Ensure the presence of a reservoir, in which the dirty water will be transported in the future and taken to the disposal point;
• To install pumping equipment;
• Connect the pump to the electrical system and hoses;
• In the process of pumping out, if necessary, add water to dilute wastes of increased density.

Features of the choice of household pump from a technical point of view

• Housing material. The pump works in an aggressive environment, but its influence should be to him at all. Corrosion-resistant Are considered plastic, cast iron and steel.
• The power indicator. The performance of pumping equipment as a whole depends on this indicator. However, when choosing a pump to drain the sewage system at home, the first thing to be guided by the indicators of the volume of the discharge pit (septic tank).
• Maximum head of the pump. Refers to the quality characteristics of the unit. The parameter that determines which height the pump can raise the liquid. In most cases, in practice, it is slightly lower than in the description of the manufacturer.
• Type of cooling. There are two ways: cooling the engine with pumped liquid and oil. The second option is considered more acceptable, since the cooling efficiency is higher. But it is worth noting that the price index of such pumps is higher, and it will pay for itself only if the household pump for pumping out the sewage system is in frequent use.

What conditions still need to be taken into account when choosing a pump?

1. The depth of the septic tank and the distance from the pumping site to the installed tank for export. Based on these criteria, the necessary lifting capacity of the pump (unit head) is calculated. Lifting height = (pit depth + horizontal distance to the pumping point of the aquatic environment) / 10.
2. The volume of the drain pit will help determine the choice of engine power of the device. Before choosing a pump to drain the sewer, you need to know the parameters of your cesspit, since this is considered one of the most important.
3. The diameter of the inlet and outlet hoses, which act as the main link in the chain "septic tank - pump - tank for export." The so-called binding element.
4. Estimated density of the sewage mass. It will help to choose the equipment with the appropriate equipment: with a chopper or without it.

Is it worth saving on the manufacturer?

Of course, buying a pump for pumping sewage at home, the preference is best given to the equipment of well-known brands that have long been in the lead in the building materials market and have earned authority among consumers. These pumps are worth a little more expensive, but in the qualitative characteristics of the unit, its practicality and reliability, one will not have to doubt.

Other ways to drain the sewer at home

Pump drainage in a private home or in the country can be in several ways: resort to the services of a sewage machine, equip a cesspool with a pump or use chemicals.

The first option is quite expensive, since a specialized transport can pump out a certain amount of liquid. So, if your cesspool contains, for example, 10 cubic meters of water, and the volume of the tank, which is equipped with special equipment, is 5 cubic meters, then the firm that provides this type of services will have to deal with and, accordingly, pay twice. This is unprofitable from the economic point of view.

The second way is more economical. However, before proceeding with the organization of the pumping process through the use of pumping equipment, it is necessary to decide where the waste water will go after pumping.
