What Are the Reasons for the Insufficient Flow of the Centrifugal Pump?

As a Dredge Pump Factory, let's talk to you about the reasons for the lack of flow in the centrifugal pump.

There is air in the suction line or pump, and it is necessary to discharge the gas. Leakage in the suction line to detect leakage and repair. The suction line or the discharge line valve is closed and the relevant valve needs to be opened. The suction height is too high and the installation height is recalculated. The suction line is too small or blocked.

Adjust the diameter of the inlet pipe. The impeller is damaged, causing the pumped media to be undercut. Need to replace the impeller. The impeller flow path is blocked. It is necessary to remove foreign matter in the flow path. If the impeller speed is insufficient, find out the cause of insufficient speed, such as improper motor matching, and adjust it. The direction of the impeller is wrong, and the rotation direction of the motor or prime mover is re-adjusted. The lift of the device is higher than the lift of the pump and needs to be recalculated.
