To provide a centrifugal pump capable of relaxing a thrust load applied toward a suction port side of a pump case by a simple structure without arranging a balancing hole nor a rear blade on an impeller, and of extending the life of the pump.
A pump housing part 7, and a suction port 9 and a discharge port 11 opened to the pump housing part 7 are formed on the pump case 1. The impeller 6 housed in the pump housing part 7 is rotatably journaled by a shaft body 23 arranged in the pump housing part 7. A drive means rotationally driving the impeller 6 around the shaft body 23 is provided. The delivery direction of a fluid delivered from the outer periphery of the impeller 6 is tilted toward the suction port 9 with respect to the radial direction of the impeller 6.
