Scope of application and selection of drainage pump
The drainage pump is a manual or motorized device for pumping or pumping various volumes of water. For residents of the area, where there are frequent flooding of basements and cellars, this drainage device is especially important. Many other problems are solved with the help of a drain pump.

Scope of drainage technology
In private homes that are not connected to the sewage system, domestic wastewater is discharged into a cesspool. In a long period of rain or with intensive use of water in the house, the pit may overflow. A bilge pump will help free the pit from excess water. Dirty water can be diverted by means of a pumping device into the gutter.
A frequent occurrence during the period of melting snow and spring floods is the flooding of basements, cellars and basements in houses, as well as wells and boreholes. Basement water pumping pump - the obvious solution to the problem. In addition, if the site has a pool or other artificial reservoir, it requires regular replacement of water. This process is organized through drainage pumps.
Dug in for the construction of the deepening, lowlands in areas in rainy weather are filled with water. For pumping water from the pits and puddles also useful mud pump. Use it for organization of watering garden plants, irrigation of greenhouses with water from a well or a nearby reservoir. Some models of drainage systems are designed to pump clean water.
Schematic diagram of the drainage pump
The device of the drainage pump used in everyday life is not complicated and consists of the following parts:
- housing;
- electric motor;
- pump unit.
A mains powered motor drives a shaft with blades.Discharged air is formed inside the pump unit, due to which water is sucked from under the suction device under pressure. Under influence centrifugal force of rotating blades the liquid is pushed into the pipe of the supercharger, from where it is pushed out to a certain place of the section through the discharge hose (for dirty water, a sump or tank). A suction screen is used to filter large fractions.
A submersible pump float switch monitors the water level and automatically turns the device on or off. This prevents flooding and "dry" stroke of the unit.
Types of drainage pumps
Modern industry produces a wide variety of drainage devices, including submersible devices and surface pumps for dirty water. The main difference of the species is reflected in their names, there are few special principal differences.
Submersible models
Devices work in submerged position. Differ in small dimensions and weight. Can be used in a universal format:
- for pumping clean and polluted water;
- for pumping water from pools and wells;
- for watering and irrigation beds.
The device is equipped with a waterproof case and a float that regulates the depth of immersion. Many models provide automatic mode of operation.
Among the shortcomings of submersible models, it can be noted that the level of water rise is limited to 10-20 meters, and there is also no possibility of water purification during pumping. In the process, the probability of clogging of the pumping chamber is not excluded.
Surface Devices
Installation of a surface drainage pump does not require immersion: only the suction hose is lowered into the water. The device is powerful, capable of raising water by several tens of meters. Differs in reliability and durability, it can work in automatic mode. The disadvantages include published when working noise level and limited suction depth - up to 7 meters.
Which drain unit to choose
When choosing a device should focus on the intended operating conditions:
- height of lifting fluid;
- workload;
- water temperature;
- fluid contamination level;
- technical conditions of installation.
For household and household needs enough power of 1000-3000 watts.The more powerful the engine of the device, the more productive it is and it consumes more electricity. If the device is selected for construction purposes, then you can pay attention to the sediment capacity up to 5000 watts. Water pressure depends on the height of the lift and the distance of its lead. The range of these characteristics is indicated in the documentation for the device.
Also need to pay attention to the following points.
- You need to know the diameter of the intake and outlet nozzles for the selection of appropriate hoses.
- Permissible solids in water. If the operating conditions do not correspond to this parameter, the device will quickly become clogged and may fail.
- Maximum depth of immersion / intake.
Important! Drainage devices are not suitable for cleaning sewage facilities from fecal water. For sewage should purchase a special sewage pump.
Overview of popular brands
Summer residents for watering their landings use submersible pumps. Good reviews on models of this type in models of Russian brands.

The rating of drainage pumps of Russian companies is torn off by the trademark Malysh, which occupies the third position.Prices for products, depending on the characteristics, range from 1,500 to 3,500 rubles. The manufacturer gives a warranty for 1 year. Pumps are different compact dimensions, low weight. Instrument power varies from 240 to 300 W, capacity from 18 to 25 liters / minute, immersion depth from 3 to 5 meters, lifting height up to 60 meters.
Vortex
Whirlwind company produces not only submersible and surface pumps for various areas of household and economic activities, but also more powerful drainage pumping stations, as well as faecal pumps. Products of this brand in the ranking occupy the 2nd position. Prices depending on the type and characteristics of the device range from 2,000 to 7,000 rubles. The range of models includes pumps for clean and dirty water with different performance, intake depth and lift height that meet international quality standards.
Jilex
The first position of the rating is reserved for the Dzhileks brand's drainage equipment, which is focused on various household and household needs, as well as on the use in the needs of small businesses. Technique is different high degree of reliability and resistance to loads, as well as simple maintenance.The company has created a network of centers specializing in the repair of drainage pumps and stations of its brand. Prices for products vary in the range of 3000 - 19000 rubles.
Independent installation of a drainage pump
Manufacturers give all the details of the apparatus installation in the instructions; for proper installation, you must follow the prescribed algorithm. A typical sequence of steps is as follows.
- Mount existing equipment (carried out in a vertical position).
- A hose / main pipe is connected to the outlet (discharge port). The connection is carried out using the supplied connecting parts.
- If the pump is equipped with a 3-phase motor, it is necessary before operation. check the correct connection of the phases. To do this, turn on the machine and determine the direction of rotation of the shaft. The correct connection of the phases is indicated by a clockwise rotation. Otherwise, you need to turn off the device and change the order of the phases.
- Before immersion, the pressure connection must be directed upwards.
