The practicability of the sewage pump should be considered in the selection process. Among them, there is a preliminary understanding of the nature of the sewage, such as whether it contains large particles, long fibers, corrosive liquids, and flammable and explosive materials in the liquid. When the user purchases the problem, our salesperson will also communicate with the customer, and the selection engineer will help the customer determine the final product model. The most critical issue for sewage pumps is reliability, because the medium that needs to be transported is some mixed liquid containing solid materials. This problem makes sewage pumps more demanding in terms of sealing, motor carrying capacity, bearing arrangement and selection, etc. The pump must be high, so when selecting the model, it is necessary to understand the sealing reliability and carrying capacity of the sewage pump.

In order to improve the service life of sewage pumps, most manufacturers at home and abroad are now thinking of ways to protect the pumps, that is, when the pumps leak, overload, over-temperature and other faults, they can automatically alarm and automatically shut down for repairs.
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 just a remedy after the pump fails. It is a relatively passive method.
The key to the problem should be to start from the root, and completely solve the problems of the pump in terms of sealing, overload, etc. This is a more proactive approach. For this reason, we apply the auxiliary impeller fluid dynamic sealing technology and the pump’s no-overload design technology to the submersible sewage pump, which greatly improves the reliability and carrying capacity of the pump seal and prolongs the service life of the pump.
