Product Q&A

Q:What is your MOQ?

One set.

Q:How long is the warranty?

One year for main construction warranty.

Q:What is the payment method?

Usually by T/T, 30%-50% deposit payment once PI/Contract confirmed, then the remaining balance will be paid after inspection and before shipment via T/T or L/C.

Q:What are the causes of no flow or insufficient flow?

There is air in the suction pipe or pump, which needs to be discharged. Air leakage is found in the suction pipeline, and the leakage is repaired. If the valve of suction line or discharge line is closed, relevant valve shall be opened. If the suction height is too high, recalculate the installation height. The suction line is too small or blocked.

Q:How to resist cavitation in centrifugal pump?

Improve the structure design from the suction to the impeller of the centrifugal pump; Adopt double stage suction impeller and use anti-cavitation material.
