ZW Self-priming Sewage Pump

Product Overview：
ZW self-priming sewage pump，Not only can be like the general water self-priming pump that does not need to install the end of the valve, without irrigation water，but also can convey big solid sewage,solid diam. can reach 60% of pump outlet diam.and fiber which is 1.5 times longer than impeller diam,Sediment, waste impurities, fecal treatment and all engineering sewage and glial liquid，Completely reduce the labor intensity of manpower, and easy to install, very little maintenance.

 
Application：
ZW self-priming sewage pump widely used in chemical, petroleum, pharmaceutical, mining, paper, fiber, pulp, textile, food, power plants and municipal sewage works, public facilities, river farming,etc.
 
Product features：
1、Strong drainage sewage ability：Special impeller anti-blocking design，to ensure that the pump is efficient.
2、ZW self - priming sewage pump energy efficient：Using excellent hydraulic model, the efficiency is 3-5% higher than the general self-priming pump.
3、Self-priming performance is good：Self-priming height is 1 meter higher than the general self-priming pump, and the self-priming time is shorter.
