PROBLEM TO BE SOLVED: To provide a pump structure which can reduce or eliminate a load applied on an existing pump setting floor surface and integrally lift a pump main part including a suction bell mouth and an impeller. SOLUTION: In the pump structure, a lifting pipe 21 is supported via a support leg 28 at a water tank base plate, the suction bell mouth 19 and a pump casing 20 can be drawn upwards by suspension support. The impeller 24 is suspension-supported at a pump shaft 30, the suction bell mouth 19 and the pump casing 20 are supported with the lifting pipe 21 via a shaft cover 29, the load of a main body casing 18 is supported at the suction water tank base plate 12, the load and the hydraulic power thrust of the impeller 24 are supported via the pump shaft 30 at the pump setting floor surface 13 different from the suction water tank base plate 12, and the load of a reducer 17 connected to the pump shaft 30 is supported.
