The required NPSH (net positive suction head) of a pump with an inducer is determined by the suction and total head performance of the inducer and the suction performance of the pump. The authors have indicated that the influence of the performance mentioned above on suction performance in combined operations 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 performance of the inducer and pump on suction performance in combined operations is investigated, and a method is suggested to predict the suction performance of the centrifugal pump with an inducer over the whole operating discharge range. The predicted results are compared with the results obtained experimentally.
