What is the reason that the submersible pump does not produce water or emit less water?

(1) Cause of failure:

1 The motor does not start.

2 The pipeline is blocked.

3 The pipeline is broken.

4 filter blocked.

5 The water absorption port is exposed to the water surface.

46 electric pump reversed.

7 The pump seal is damaged and the impeller is worn.

8 impeller or diversion shell flow channel blockage.

9 rotor broken bars.

(2) Exclusion method:

1 Eliminate circuit failures (such as low voltage or line defects) to solve the problem of pump stuck.

2 Clean up the blockage.

3 repair the rupture.

4 Clean the filter screen to remove blockages.

5 discharge pump, put the electric pump in the water, if it still does not produce water or exceed the range of use of the pump lift, it is recommended to replace the pump with high lift.

6 Change the phase sequence of the cable connector so that the motor steering is consistent with the pump's steering.

7 Replace the new seal ring and impeller.

8 Clean the flow path and remove the blockage.

9 Replace the rotor.
