Flowrate coefficient and head governed by the leading edge and trailing edge respectively are the two important performance paramenters of an inducer. In this paper, both the parameters were studied and analyzed. Based on the Brumfield criteria, the minimum NPSH, the maximum specific suction speed as well as the optimum tip diameter were conducted. Then a new design method of the leading edge, which matches the relations above was developed. On the other hand, a computational method of head with consideration of the hydraulic efficiency was demonstrated. At last, a developed pump with an inducer was tested and the results showed that the inducer greatly improved the cavitation performance of the pump.
