ZWL sewage self-priming pump adopts a direct connection structure. Compared with similar domestic products, it has the characteristics of simple and compact structure, less vibration, good self-priming performance, strong sewage discharge capacity, high efficiency and energy saving, and easy use and maintenance.

product overview

ZWL sewage self-priming pump integrates self-priming and non clogging discharge, adopts axial reflux external mixing, and through the unique design of the pump body and impeller flow channel, it can not only eliminate the need for bottom valves and irrigation water like general self-priming water pumps, but also suck and discharge liquids containing large solid particles and long fiber impurities. It can be widely used in municipal sewage engineering, river pond aquaculture, light industry, papermaking, textile, food, chemical, electrical, fiber, pulp and mixed suspension chemical media impurity pumps.
