The sewage pump is the most critical issue is the reliability problem, because of the need of transmission medium of solid materials are mixed with liquid, the problem of the sewage pump in a sealed, motor bearing capacity, bearing arrangement and the use of requirements to be higher than the average pump, so in the selection, we must clearly understand the sewage pump the reliability of sealing and bearing capacity. Stainless steel self priming pump

In order to improve the life of the sewage pump, most manufacturers at home and abroad are thinking about the pump protection system, that is, when the pump has leakage, overload, over temperature and other failures, it can automatically alarm and stop automatically for repair.

We also feel that it is necessary to set up the protection system in the sewage pump, and it can effectively protect the safe operation of the electric pump. But this is not the key to the problem. The protection system is only a remedy after the failure of the pump. It is a relatively passive way.

The key to the problem should be a radical solution to the problems of the pump in the aspects of sealing and overload, which is a more active approach. Therefore, we applied the auxiliary impeller hydrodynamic seal technology and the pump overload free design technology to the submersible sewage pump, which greatly improved the sealing reliability and bearing capacity of the pump, and prolonged the service life of the pump.
