In the process of using the submersible slurry pump, the fault of low head will appear. What is the reason for the low head of the slurry pump? What is the solution? Let's take a look:

Reasons for low lift:

1. Intake pipe system;

2. The suction pipeline or impeller is blocked;

3. The inlet valve of submersible slurry pump is not expanded or the valve has been damaged, resulting in pump cavitation;

4. The pump head is lower than the actual head of the pipeline, resulting in small pump flow;

5. The NPSH of the pipeline is less than that of the submersible slurry pump, resulting in small pump volume;

6. The concentration of slag slurry is too high.

terms of settlement:

1. Eliminate the cause of air intake;

2. Reduce the slurry concentration of the slurry pump or change the pump with a larger diameter;

3. Expand the inlet valve or replace it with a new one;

4. Increase the head of submersible slurry pump;

5. Remove blockage;

6. Build pipeline devices so that the NPSH of the pipeline is greater than the NPSH required by the pump, or replace the pump whose NPSH performance meets the requirements of the pipeline device.

I believe that through reading the article, if you encounter the low head of submersible slurry pump again, you won't be at a loss. Mastering more equipment knowledge will help you at the critical moment.
