The invention provides a water-power-driving centrifugal pump which is wide in an application occasion range. After the pump is driven, the depth of water pumping can reach above 20 meters, and the pump can meet water pumping requirements under the severe environment. The water-power-driving centrifugal pump comprises a centrifugal pump and further comprises a water turbine. The centrifugal pump and the water turbine are installed in a coaxial mode. The centrifugal pump comprises a pump body, a pump cover, an impeller and a rotary shaft. The water turbine comprises a pump cover, a volute and a turning wheel. The impeller and the turning wheel are installed at the two ends of the rotary shaft in a coaxial mode, the impeller is installed at the font end of the rotary shaft and connected through a bearing, and the turning wheel is installed at the rear end of the rotary shaft and connected through a bearing. A shaft sleeve is installed in the middle of the rotary shaft. The pump cover of the centrifugal pump and
