AWZB-K automatic peripheral self priming pump consists of four parts, motor, water pump, sealing part and control system. The motor is asynchronous type, and the impeller has peripheral structure.

The control system is used to achieve the automatic running according to the water pressure, and the start and stop of our machine is controlled by the valve. The electronic pressure switch applied is adjustable and visible which means that the start and stop pressures can be adjusted depending on the actual working pressure. In this way, the automatic working is realized, and there is no need to cut off electricity. In addition, our pump has a pressure gauge which facilitates the adjustment.
