Summary

WQK/QG cutting type sewage pump is composed by 3 parts of pump, seal and motor. The motor lies in the upper part of pump, using hard alloy mechanical seal between pump and motor, each fixed rabbet adopting “O”shape oil-proof rubber sealing ring as static seal.

Characteristic

4KW and below 4KW motor are equipped with thermal protection device, which can disconnect the power to protect motor under the situtation of phase failure of pump, overload and motor overheat. Impeller is semi-open single channel structure, pump cover is groove shape. By high speed rotation, the impeller can chop the sun dries and discharge them, and also can run full head. The interval of pump cover and impeller is adustable. When the hydraulic performance reduced due to wear of impeller and pump cover, only adjust the position of pump cover, the head will be improved greatly. 

Application

This series of pump has the advantages of strong passing ability, good cutting performance etc. Widely used for construction site, mine, factory, and republic environment protection. It’s able to pump sewage with long fiber, plastic bag, pieces of cloth, rope, leaves etc. Also can be used for clariifed water irrigation.
