Product Details

ZW Self priming sewage pump not clogging centrifugal pump can be made of cast iron or stainless steel material. Connection type between the pump and motor can be with shaft coupling or closed coupling.

ZW series self-priming sewage pumps are with self priming and sewage discharge. It means the pumps can not only be self priming as the same as ZX series self priming pump for clean water without foot valve and pouring water but also suck and discharge the large grain and long fiber and sediment and impurity in the waste water. And the performance is very steady. It is very convenient to operate and move and install and maintain.

①Environment temperature≤45℃，Liquids temperature≤120℃。

②Liquid PH: Cast iron pump :6～9，Stainless steel :1～14。

③Max grain diameter can be 60% of caliber for pump. Length of fiber can be 5 times as caliber for pump.

④Impurity weight into liquid can not more than 15% of liquid weight. Liquid density≤1240kg/cm3
