How to choose a drainage pump?

Since drainage pumps are designed for pumping water, when choosing them, you should pay special attention to the technical characteristics of a particular model.

Basic selection criteria include:

1. Type of equipment . All drainage pumps are divided into surface and submersible. Devices of the first type are placed on the edge of a flooded area, and water is drawn through the upper pipe. Submersible models are placed directly in the water, and since the body is sealed, constant exposure to moisture will not harm the equipment.
2. Power consumption . The higher this indicator, the faster the device will be able to pump out liquid from a reservoir or flooded room.
3. Depth of liquid intake . This characteristic determines the maximum depth from which the device can suck up liquid. As a rule, most sump pumps cannot be immersed in water deeper than 8 meters.
4. Particle size . Since water from flooded areas may contain solid particles, it is advisable to have a special mesh at the suction port to trap contaminants.

It is highly desirable that the drainage pump be equipped with a float mechanism. It monitors the moisture level in the tank, and if it drops below normal, the device will automatically turn off.

The best submersible drainage pumps from 10,000 rubles

Gnome 40-25T with r/o

A good pump for pumping out liquid, the temperature of which should not exceed 60°. It can become part of the water supply system, but impurities in the water should not exceed 10%. The design is represented by a powerful engine (4 kW), which provides high productivity (40 cubic meters/hour) and high head (25 m). The build quality is also top notch. The body is made of cast iron, which will have a positive effect on service life.

The pump weighs 50 kg, and therefore, when immersed in a pit, you must have a cable and a stand on hand, on which the device will stand tightly. The manufacturer sets a limitation, noting that the continuous operation cycle should not exceed 10 minutes.

Selection rules

To decide which drainage pump is best for dirty water, you must first decide what tasks it will perform, taking into account the following factors:

• Type of pumped liquid.

That is, if you have to pump out clean water, without any admixtures of sand, silt and other contaminants, you can use models with a small nominal diameter. To clean construction pits, cesspools and other places with heavy contamination, it is necessary to use appropriate types of pumps equipped with special filters.

• Performance.

In this case, you should focus on the nature and degree of use of the pump (the amount of liquid that it has to pump out per unit time), taking into account that raising one meter of water vertically is equal to ten meters pumped out from the horizontal plane.

Please note: models with a power of 200-400 W can pump up to 80-100 liters of liquid per minute. “Middle class” pumps with a power of 400-1000 W - up to 200-300 liters per minute.

• Location of the suction pipe.

It can be bottom, side and top. To clean flooded rooms and containers, you should choose models with a lower pipe location. For collecting liquid from silted reservoirs - with an upper one.

• Availability of additional functions.

This is an automation system, float start and installation system, protection against overheating and short circuit, etc. When buying a drainage pump for dirty water, before choosing this device, you need to pay attention to the following points:

• For a family of 4 people and servicing a plot of 6 acres, a pump with a power of 120 l/min is sufficient.
• The device must be connected to the power source using a differential circuit breaker.
• Drainage pumps must not be used to pump liquids that are flammable or chemically aggressive.
