When installing the pump, how much is the clearance between the pump and the motor connector? The pump has just been installed and started to turn off.
Affect the pump output, reduce efficiency! Clearance is too small, will cause the impeller and pump shell friction, wear and tear.
The gap between the impeller and the pump shell will cause the pump within the high pressure zone of the water flow through the gap area of low pressure
In order to increase the return to reduce the internal leakage resistance and service life of the delay of the impeller and pump casing, junction with sealing ring in the pump casing and impeller aid, sealing gap should be between 0.25 ~ 1.10mm.
