Claims

[Claims for Utility Model Registration] One half of the elongated rod-shaped body consists of a motor part and the other half a pump part, and an axially movable check valve is provided at the end of the pump part to open and close the discharge port. and a rod-shaped submersible pump having a discharge cylinder connected with a plurality of radial vanes that guide the movement of the check valve to open the discharge port from the surroundings and regulate the open position, A concentric cylinder frame is formed inside the discharge cylinder by the plurality of blade plates, and a blind cylinder having a bottom is fixed in the cylinder frame with the bottom facing the open end of the discharge cylinder, and the non-return check A shaft protruding toward the open end of the discharge tube is provided at the center of the valve, and a guide hole is provided at the center of the bottom of the blind tube through which the shaft is guided in the axial direction,
A rod-type submersible pump characterized in that a coil spring is installed between the bottom of the blind tube and the check valve to press the check valve against the discharge port and close it.
