Submersible Pump

The biggest feature of the deep well pump is that it integrates the motor and pump. It is a pump immersed in the groundwater well for pumping and conveying water, and is widely used in farmland irrigation and drainage, industrial and mining enterprises, urban water supply and drainage and sewage treatment. Since the motor submerges into the water at the same time, the structural requirements for the motor are more special than those for general motors. The motor structure is divided into four types: dry type, semi dry type, oil filled type and wet type.


1. The motor and water pump are integrated to operate in the water, which is safe and reliable.

2. There are no special requirements for well pipes and lift pipes (i.e., steel pipe wells, ash pipe wells, earth wells, etc. can be used; under pressure permission, steel pipes, rubber pipes, plastic pipes, etc. can be used as lift pipes).

3. The installation, use and maintenance are convenient and simple, and the floor area is small, so there is no need to build a pump room.

4. The results are simple and raw materials are saved. Whether the use conditions of submersible pumps are appropriate and properly managed is directly related to the service life.

Operation, maintenance and servicing

1. During the operation of the electric pump, it is necessary to frequently observe the current, voltmeter and water flow, and strive to operate the electric pump under rated conditions.

2. The valve shall be used to regulate the flow and lift, which shall not be overloaded.

The operation shall be stopped immediately under one of the following circumstances:

1) Current exceeds rated value at rated voltage;

2) Under the rated head, the flow decreases greatly compared with that under normal conditions;

3) The insulation resistance is lower than 0.5 megohm;

4) When the dynamic water level drops to the pump suction inlet;

5) When electrical equipment and circuits are not in accordance with regulations;

6) The electric pump has a sudden sound or large vibration;

7) When the protection switch frequency trips.
