Abstract Based on similarity theory and expressions of water head and efficiency curves of pumps and pump sets,a mathematical model for predicting water head and efficiency of prototype pumps and pumping sets is put forward.According to the model,the pump set characteristics are predicted and the optimal hydraulic model of pumps suited to the Shangqiao Pump Station is selected.The optimal selection result is 350ZMB-3.8 model.After reconstruction,the single pump flow rate increases by 5~8 m~3/s under the same input power.
