Brief introduction
ZW series self priming non-clog waster water pump is a type of centrifugal pump that use an air-water mixture to reach a fully-primed pumping condition.The Series ZW self-primming pumps are newly developed self-priming centrifugal pumps for waste water . The pumps have the compact structure, the long life expectancy and the high energy-efficiency to operate smoothly and reliably. It is just need to check the amount of liquid in the pump for self-priming before starting pumping. The self-priming centrifugal pumps are widely used for applications in the chemical, dyestuffs, petroleum, pharmaceutical, brewery, paper and pulp, metallurgical and mining industries and for oil discharge of oil carrying ships, as well as for water supply and sewage drainage of municipal, industrial and emergence services.

Features
1,The kind of pump could self prime after first time use and no need to install bottom valve;
2,ZW series self priming non-clog waster water pump adopts special big flow impeller structure,so it could deal with liquid with solid and long fibers.
3,Direct drive by motor,the pump rotate anticlockwise viewed from dive side;
4,The pump is simple structure,strong self priming performance,easy to repair and energy saving.
