Research and development of submersible sewage pump

In order to improve the life of submersible sewage pumps, most manufacturers at home and abroad are trying to find a way on the pump protection system, that is, when the pump leaks, overload, overtemperature and other failures can be automatically alarm, and automatic shutdown for repair.
However, we believe that it is necessary to set up a protection system in the sewage pump, which 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, is a more passive approach. The key to the problem should be to start fundamentally and completely solve the problems of the pump in sealing, overload and so on, which is a more active way.
Therefore, we apply the fluid power seal technology of the auxiliary impeller and the non-overload design technology of the pump to the submersible sewage pump, which greatly improves the reliability and bearing capacity of the pump seal, and prolonging the service life of the pump.
