PURPOSE: A serious connection type multistage submersible motor pump is provided to freely control the pressure of fluid by connecting multiple separated motor pumps through a hose. CONSTITUTION: A serious connection type multistage submersible motor pump(1) comprises a housing(10), a central tube(20), a rotor(30), an impeller(31), and a stator(40). An inlet(11) is formed in one side of the housing, and an outlet(12) is formed in the other side thereof. The central tube is arranged inside the housing in a longitudinal direction. The rotor is rotated around the central tube and has magnetic force. The impeller is formed on the inner surface of the rotor in a screw shape. When power is applied to the stator, the stator rotates the rotor.
