ZW type Self-priming sewage pump, according to ZX type self-priming centrifugal pump and QW type submersible sewage pump, the structure and the performance of, from the advantages of similar foreign products developed a set of self suction and discharge in a new type of pump. Can be like water self-priming pump that does not need to install the valve, without irrigation water, and aspirate containing large particles of solid diameter of exit diameter of 60% and the fiber length for the impeller diameter 1.5 times the dirt, sediment, abandoned mine impurity, manure treatment and all engineering foul substance and colloid liquid, reduce the labor intensity of human, and convenient installation and use, little maintenance, performance reached the international advanced level, with wide application market and development prospects.
Product features:
1. Strong sewage capacity: special impeller anti blocking design, to ensure that the pump is efficient and no blockage.
2. High efficiency and energy saving: using excellent hydraulic model, the efficiency is higher than the general self suction pump 3~5%.
3. Self suction performance is good: self suction height than the general self priming pump 1 meters high, and self priming time is shorter.
