What are the solutions to pump mechanical seal leakage?

February 27, 2023

Mechanical seal is also known as face seal, which has a pair of end faces perpendicular to the axis of rotation. Under the action of fluid pressure and compensating mechanical external elastic force, the end face depends on the auxiliary seal to keep fit with the other end, and relative sliding, so as to prevent fluid leakage.

Self-priming pump should how to install & what matter need pay attention to?

February 27, 2023

Self-priming pump is a self-priming centrifugal pump, which has the advantages of compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long life, and strong self-priming ability. Pipeline does not need to install the bottom valve, before the work only to ensure that there is a quantitative primer in the pump body. Different liquid can use different materials of self-priming pump.
