摘要：Start your abstract here…For a low specific speed centrifugal pump with the requirement of high efficiency of 68% and non-overload power characteristics, series experimental studies, by matching 9 volutes with 19 impellers were done. By combining the former research results about the splitters and the no n-overload theory in centrifugal pump, the theoretical conditions to achieve the property of non-o verload in a centrifugal p ump with splitters was analyzed, and formulas to estimate the maximum shaft po wer and its position are derived. Based on the requirement of high efficiency and non-overload, blade outlet angle2β, blade outlet width2b, volute throat areatFand the inlet diameter of splittersiDwere chosen with three levels to design a normal L9 （ 34 ） ortho gonal test scheme. Meanwhile, the optimized design scheme was determined, and corresponding test was done also, it demonstrates that the experiment purpose was reached, the design method to combine the splitters and non-overload theory is reasonable, which can get the property of high efficiency and non-overload
