PROBLEM TO BE SOLVED: To provide a fugal pump with a good durability capable of enhancing resistance to hydraulic pressure in the middle of a casing where the amount of deformation caused by hydraulic pressure is the greatest. SOLUTION: A fugal pump includes a water inlet 11; an outlet port 12; a water intake passage 21, and a water supply passage 22; a first casing 1 including a shaft hole 17a for retaining one end 4a of a spindle 4 for supporting rotatably an impeller 7; and a second casing 2 that forms a swirl chamber 10 for accommodating the impeller 7 disposed via a partition plate 24 between the first casing 1, and includes a shaft hole 17b for retaining other end 4b of the spindle 4. In the fugal pump 30 that transmits rotations of a motor 9 to the impeller 7 by magnetic force of magnets 5a, 5b, a ball bearing 31 for supporting a thrust load of the spindle end 4b is disposed in the shaft hole 17b of the second casing 2.
