ZW type self-priming sewage pump, also known as solid-liquid pump or impurity pump. The hydraulic design of this series of pumps is unique. The impeller is shrunk in a separate impeller chamber, and the impeller chamber is connected with a pressurized water chamber. When the impeller rotates, the liquid in the pump produces a strong axial vortex effect, which causes a vacuum at the inlet and a lift at the outlet. Therefore, impurities can be discharged from the pressurized water chamber, so its flow channel is completely unobstructed, and its sewage effect is unmatched by other self-priming sewage pumps. The ZW self-priming eddy current non-clogging sewage pump produced by this unit does not need to install a bottom valve like a general self-priming clean water pump, and can also suck and discharge large solid blocks, long fibers, sediments, waste ore impurities, manure treatment and All engineering sewage. Self-priming sewage pump can be widely used in municipal sewage engineering, light industry, papermaking, textile, food, chemical, electrical, petroleum, mining and pond aquaculture and other industries. Self-priming sewage pump is currently the most ideal impurity pump for pumping solid particles, fibers, pulp and mixed suspension in China.
