It is separated in the separation chamber air out from the outlet pipe to drain, ZW80-25-40 pump, and the water is still flowing through the impeller backwater hole around the outer edge, and mixed with the air suction pipe. This cycle repeated gradually sucked the air pipe drained the water into the pump, ZW80-40-16 pump, complete self-absorption process. Self-priming pump diaphragm pump sewage pump gear pump screw pump the same, the difference is only the outer edge of the backwater does not flow to the impeller, and the impeller inlet flow. Wheel self-priming pump is a water ring water ring pump impeller wheel and combined in a single housing, with water ring round the gas discharges, to achieve self-absorption. When the pump is working properly, it can cut off the water through the valve and pump impeller ring round passage, Jianchang County, pump, and let go of liquid water within the ring wheel. Jet pump, a combination of centrifugal pumps and jet pumps (or jet) is made, relying injection device, creating a vacuum to achieve suction at the nozzle. Jianchang County priming pump, ZW80-25-40 pump, stone camp (high merchant) provided by the Shijiazhuang-Pump Co., Ltd. faction. Shijiazhuang-school Pump Co., Ltd.
