For the problem of sewage pump selection, Xiaobian will take the sewage pump produced by Zhejiang Shenyi Pump Industry as an example to analyze it. The following three types of sewage pumps are widely used: QW (WQ) submersible sewage pump, WQP stainless steel non clogging sewage pump and ZW self-priming sewage pump. The corresponding advantages of each category are different, so it is necessary to analyze the needs of buyers.

Next, we need to carry out today's topic by category. QW (WQ) submersible sewage pump is mainly used in potential sewage. Its unique impeller design makes the sewage pump non clogging. It is relatively common sewage pump. WQP stainless steel non clogging sewage pump is mainly made of stainless steel, which is not easy to be corroded by the transmission medium.

ZW self-priming sewage pump is a unique type of sewage pump. What is the self-priming function? It is to discharge the air through idling, so as to absorb the medium in the air until the medium fills the pump body of the sewage pump. The whole process is called self-priming; Other sewage pumps are different in installation mode, impeller diameter and connection mode between motor and pump. At the same time, such self-priming pump is equipped with self-priming device, which is used in complex situations.
