JET type jet electric pump (hereinafter referred to as electric pump) is mainly composed of three parts: electric motor, water pump, and seal. The electric motor is an asynchronous motor; the unique structure of centrifugal impeller radial guide vane jet tube is adopted. The principle is that the pressure water first passes through the nozzle to create a vacuum, and then the low-level liquid is sucked into the pump inlet and pressurized and discharged by the pump, with self-priming function. The water pump and motor are equipped with a single end mechanical seal, and the water blocking ring rotating on the shaft plays an auxiliary role in water throwing and isolation. The fixed sealing part adopts an "O"-shaped rubber sealing ring for static sealing.
