Need not be filled with water in the suction line can be automatically pumped water centrifugal pump called priming pump. Many 200ZX350-65 priming pump structure type pump, wherein the outer mixing self-priming pump works: The pump housing before the pump starts to fill with water (or water pump housing itself there). After starting the high-speed rotation of the impeller channel impeller in the water to the scroll, then creating a vacuum 200ZX280-63 inlet pump, so water Check the door open, the intake air tube into the pump, and after reaching the outer channel impeller edge. Then with the right backwater hole stream water confluence 150ZX160-80 pump, along the spiral flow. Since the liquid in the volute continue to impact the cascade, constantly being crushed impeller, on strong mixing with air to produce air-water mixture, and continue to flow so that air and water can not be separated. 100ZX100-65 pump, pump, stone sent by Shijiazhuang-Pump Co., Ltd. faction.
