As it has been proven, the design of impeller meridional shape directly influences the performance of multistage centrifugal pump. In this study, the five parameters of the double-arc meridional shape design method were selected as the design variables. A multi-point hydraulic optimum design method of impeller meridional shape for multistage centrifugal pump performance improvement was presented. The maximum hydraulic efficiency and effective head were chosen as the objective functions. The design of experiment method was applied to generate different impeller meridional shapes and a total of 50 sampling models were generated using the Latin Hypercube Method. The Reynolds Average Navier Stokes equations were adopted to conduct the numerical calculations. To validate the performance improvement of the optimal design model, efficiencies of the optimal design model at flow rates of 0.8Qref, 1.0Qref, and 1.2Qref were compared with the original reference model. The optimal efficiencies under the three operation conditions increased by 1.9%, 1.6%, and 0.9%, respectively. In addition, the CFD analysis of a two-stage multistage pump assembled by impellers, continuous diffuser and return vanes was conducted. The cavitation performance was also validated.
