ZW non-clogging self-priming sewage pump

ZW self-priming sewage pump, through the novel structure of the impeller and pump body, the pump can not only be like the general self-priming pump without the installation of foot valves, but also can pass through larger particles and longer fibers, which has a broad application market and development prospects. ZW 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 to the pressurized water chamber, when the impeller rotates, the liquid in the pump produces a strong axial vortex effect, so that the inlet causes a vacuum, and the outlet produces a head. Therefore, impurities can be discharged from the pressurized water chamber, so its flow channel is completely unblocked, and its sewage discharge effect is incomparable to other self-priming sewage pumps. The ZW self-priming sewage pump produced by this unit can be like the general self-priming clean water pump without installing a foot valve, and can also absorb and discharge large particles of solid blocks, long fibers, sediments, waste mineral impurities, fecal treatment and all engineering sewage.

Self-priming sewage pumps can be widely used in municipal sewage engineering, light industry, papermaking, textile, food, chemical industry, electric power, petroleum, mining and river pond aquaculture and other industries. The self-priming sewage pump is an ideal impurity pump for pumping solid particles, fibers, slurries and mixed suspension media in China.
