ZW self-absorption sewage pump

Product Overview: ZW self-priming vortex non-clogging sewage pump, also known as solid impurities pump or pumps. This series of unique hydraulic design, wheel is reduced in a separate impeller chamber is connected to the impeller chamber pressurized water chamber, when the impeller rotates, the liquid inside the pump have a strong axial vortex effect, making imports resulting vacuum, exports generate lift. Thus impurities may be discharged from the pressurized water chamber, so it is completely smooth flow channel, and its effect is the other self-priming sewage pump sewage unparalleled. The unit production XZW self-priming eddy non-clogging sewage pump can be as general as a generalization that does not require water pump foot valve, double suction may contain large solid blocks, long fiber, sediment, mine waste impurities, manure disposal All the sewage works. It can be widely used in municipal sewage works, light industry, papermaking, textiles, food, chemicals, electricity, petroleum, mining and farming industries Ponds. Self-priming sewage pump is currently pumping of solid particles, fibers, pulp and mixed suspension medium best trash pump.
