Pumps are widely applied in mineral processing plant, and they provide motivation of conveying the pulp. There are two kinds of pumps Xinhai expert will introduce to you---alloy slurry pump and submerged slurry pump.

In this text, we will know how to solve some common problems of the pumps:

Alloy Slurry Pump

1, Why do not the slurry pumps absorb slurry?

(1) Reason: Impeller is damaged Solution: replace a new impeller

(2) Reason: suction pipe blocked Solution: unclog the pipe

2, Some tips before using slurry pump

Pumping clean water lasting 30 minutes to wash off the slurry in the pump and pipes before close the pump

Closed end pump outlet valve

From the end pump to the first stage pump stopped step by step, and closing the corresponding seal water and cooling water

Close the inlet valve of the first stage pump;

Not allowed to close all levels of the pump when the outlet valve keep open, otherwise easy to damage pump and pipe fitting.

Submerged Slurry Pump

(1) What are the reasons that cause blocking the impeller of the submerged slurry pump?

Reasons: Medium blocks the impeller hole because the pump parking time is too long. Impeller rotation cannot produce enough centrifugal force because large granules block the impeller hole. Solution: dismantling the feeding pipe and front protection plate of the pump, then cleaning the impeller hole.

(2) How to solve the motor fault of submerged slurry pump

Use hand jigger to start motor, or replace the motor.
