Description

Product Introduction:

ZW Self-priming sewage pump is the thing blocking the company under the ZX-type self-priming centrifugal pumps and submersible pumps type QW structure and performance advantages of similar products at home and abroad, developed from the set of self-absorption and sewage in one of the new Pump species. General water pump that can not as the end of the valve installation, no irrigation water, but also draw a large number of particles containing solid and liquid impurities long fibers.

Structure Description

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.

Range of Application:

It is applicable to transport the sewage and filth containing grains or pump the clear water and corrosive medium in such industries as chemical engineering ,petroleum,pharmacy,mining, paper making, cement mill,steel works, power plant, coal processing ,drainage system of city sewage plant, public works and construction site.
