PROBLEM TO BE SOLVED: To provide a motor pump which can smoothly discharge foreign matters mixed into fluid without disturbing the rotation of a rotor.SOLUTION: A motor pump P includes a casing 1, a shaft member 3 fixed to the casing 1, a cylindrical bearing part 4 inserted into the outside of the shaft member 3, a rotor 5 constituted by another member than the bearing part 4, and rotated integrally with the bearing part 4, and an impeller 6 fixed to one end 51 of the rotor 5. A discharge path 52 for returning fluid flowing out of the outer periphery side of the impeller 6 and circulating inside the casing 1, to the side of the impeller 6, is formed between the bearing part 4 and the rotor 5 while extending along the axial direction.SELECTED DRAWING: Figure 1 |
