The ZW series self-priming non-clogging sewage pump is a product with a unique structure that was effectively created based on ongoing domestic and international research on related technologies. The pump is the most ideal impurity pump for municipal sewage projects, pond farming, light industry, paper, textile food, chemical, electrical, fiber, slurry and mixed suspension, and other chemical media. It integrates self-priming and non-clogging sewage discharge and uses an axial reflux external mixing type. Thanks to the unique design of the pump body and impeller flow channel, it can function similarly to a general self-priming clean water pump without the need for irrigation or diversion.  This is the initial product in the home sewage pump series. With a wide application market and promising development opportunities, all of the top technical performance indices are leading in China and have attained the advanced level internationally.
