Self-priming non-clogging sewage pump is a new type of pump that integrates self-priming and sewage. It can not only need to install a bottom valve like a general clear water self-priming pump, but also does not need to irrigate and divert water, but also can suck out soil, sediment, etc. containing large particles with a diameter of 60%. The outlet diameter and fiber length are 1.5 times the impeller diameter. Waste ore impurities, excrement treatment, and all engineering sewage and colloidal liquid, completely reduce the labor intensity, easy installation and use, less maintenance, performance has reached the international advanced level, and has a broad application market and development prospects.
