• The required NPSH (net positive suction head) of a pump with an inducer is determined by the suction and total head performances of the inducer and the suction performances of the pump. The authors have indicated that the influence of the performances mentioned above on the combined suction performance of the pump with an inducer depends on the pump discharge. The operating discharge range of the pump with an inducer is divided into three parts, in which the total head decrease occurs in the inducer and/or pump sections. In this report, the influence of the suction performances of the inducer and pump on the combined suction performance is investigated, and a method is proposed to predict the combined suction performance of a centrifugal pump with an inducer over the whole operating discharge range. The predicted results are compared with the results obtained experimentally.
