Product Overview of ZW Series Self-priming Sewage Pump
ZW series self-priming sewage pump sets have the advantage of self-priming and non-clogging, can be installed without bottom valve like clean water self-priming pump, but also pumping dirty water with large particles, dirt, fibers , abandoned mine sediment impurities, and other works of sewage treatment and waste material, completely reducing labor intensity, and can make mobile type, easy installation, minimal maintenance, stable performance. 

Structure Description of ZW Series Self-priming Sewage Pump
1. ZW series self-priming non-clogging sewage pump, is mainly composed of pump body, impeller, back cover, mechanical seal, bearing, inlet valve, water valves, suction and discharge pipes, etc. 
2. In the pump body has a reservoir chamber, which is connected with the top back-flow hole and bottom circulation hole and pump working chamber, interlinked to form the axial pump back outer recirculation system. When pump stops working, the pump cavity has a certain volume of the liquid reservoir. When the pump starts, under the action of the impeller, the air is rounded up with the liquid through the gas-liquid separator, and the liquid back into the working chamber, while the gas is discharged from the pump, so as to form a certain vacuum in the pump chamber, to achieve self-absorption effect.
