ZW type non-clogging sewage pump self-priming, the Secretary based on the ZX-type structure and performance of the self-priming centrifugal pump and QW-type submersible sewage pump, drawing on the advantages of similar foreign products developed from the set of self-absorption and sewage in a a new pump. Both as a general Shimizu self-priming pump without having to install the bottom valve, without irrigation water, but also suction material containing large particles of solid export 60% of the diameter and fiber length is 1.5 times the impeller diameter, dirt, precipitation in diameter. abandoned mine impurities, excreta disposal, and all sewage works and the colloidal liquid, completely alleviate human labor intensity, and install and easy to use, little maintenance, and performance has reached international advanced level, with a broad range of application markets and development prospects. 
 The Division sewage pump by computer design and optimization, the company has strong technical force, rich production experience and improve the detection means in order to ensure stable and reliable product quality. 

 Product advantages: 
 A sewage capacity: special attempts to prevent the impeller design, to ensure efficient pump without clogging. 
 2, energy efficient: excellent hydraulic model, 3 ~ 5% more efficient than the general self-priming pump. 
 3, self-priming performance: self-priming height of one meter higher than the general self-priming pump, and self-priming time is shorter.
