The invention discloses a multiple-stage centrifugal pump with an inducing wheel and a mounting method thereof. The pump comprises a pump body, impellers and a bearing are arranged in the pump body, the bearing is connected with a motor, a seal part is arranged between the bearing and the motor, the bearing is connected with the inducing wheel, a liquid inlet pipe is arranged outside the inducingwheel, the impellers are evenly arranged on the bearing, water dispersal pieces are evenly arranged on the upper portions of the impellers, a balance device is arranged between the adjacent impellers,a water transmitting hole and a water draining groove are formed in the inner side of the pump body, and a water outlet pipe is arranged on the bottom of the water draining groove. The mounting method comprises the following steps of a, mounting of the centrifugal pump; b, bearing mounting; c, inducing wheel mounting; and d, fixed-period maintaining. The centrifugal pump solves the problem that in the running process of an existing centrifugal pump, rotation stability is poor, and cavitation is prone to generating.
