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.
