It is currently pumping of solid particles, fibers, pulp and mixed suspension and other media the best trash pump. Performance range Flow Q: 8 ~ 800 m3 / h diameter DN: 25 ~ 300mm Head H: 15 ~ 80m speed N: 2900 ~ 1450r / min Motor power: 1.5 ~ 55kw self-priming role of the principle according to the following categories: 1. Hybrid gas-liquid (including mixed-type and outer recirculation); 2. Water ring wheel; 3. jet (including liquid jet and gas jet). Working gas-liquid mixing process is self-priming pump: Because of the special structure of self-priming pump 65ZW30-50 pump, after the pump stops, there is a certain amount of memory pump water pump impeller rotation after starting again due to the effect of inhaled air and water piping 65ZW15-30 mixing pump, and was discharged to air and water separation chamber, the upper chamber of the gas-water separator gas spill, the lower part of the water returns to the impeller and suction line of the remaining re-air mixture 65ZW25- 40 self-priming pump until the pump and suction tube gas discharge all, complete self-absorption, and normal pumping. 65ZW20-14 pump, pump, Stone sent Ltd provided by Shijiazhuang-school Pump.
