PROBLEM TO BE SOLVED: To provide a motor pump having a rotor and an impeller arranged side by side in the rotation axis direction of the rotor, in which displacement of the rotor and impeller due to pressure difference of fluid in a casing is reduced.SOLUTION: A motor pump 10 includes a stator 44 arranged on the outer peripheral side of a rotor 42. The stator 44 and rotor 42 always loads a force for reducing the displacement of a rotating body 60, occurring due to the pressure difference on the low pressure side where the pressure of the fluid in a fluid path 24 is low during operation of the motor pump 10 and the high pressure side where the pressure of the fluid is high, to the rotating body 60. |
