The invention relates to a pump body, in particular to a high-lift multi-stage centrifugal pump. The high-lift multi-stage centrifugal pump comprises a pump base, a stator part and a rotor part, wherein the stator part comprises a water inlet end cover, a suction segment, a middle segment, a discharge segment and a bearing supporting part; the bearing supporting part comprises a bearing part and a bearing bush; the bearing part comprises a bearing pedestal and a sliding bearing which is connected with the bearing pedestal; the bearing bush is arranged between the sliding bearing and a rotating shaft; the rotor part comprises impellers, the rotating shaft, a shaft sleeve and a balance disk; the bearing part and the bearing bush adopt a horizontal split structure; the tail end of the rotating shaft is provided with a balance disc wear indicating device; and the first-stage impeller has a double-suction structure, while the other stages of impellers have single-suction structures. Due to the high-lift multi-stag
