Speed ​​mismatch, pipeline blockage, impeller wear or too high suction head.

Check mounting stability, bearing wear, rotor balance, or pipe support.

Power supply problem (unstable voltage, phase loss), excessive load, or lack of bearing oil.

Lubricate bearings regularly, clean impeller blockages, and check the seal

.

Flow rate, head, medium characteristics (if containing particles, a sewage pump should be selected) and energy efficiency standards.

This may be caused by a motor short circuit or ground fault (measure insulation resistance with a megohmmeter), or an overload due to impeller blockage or bearing failure.
