A small, light-weight and high revolution (rated 16000 rpm) centrifugal pump with a booster was made for the experimental purpose and the performance test was carried out up to 11 000∼12 000 rpm the allowable speed of the test motor. In this report, authors showed the performances and charactristics of the pump, using coefficients for example. [numerical formula] According to the test result, it was clarified that the leakage and circulating water were decreased by the use of many radial grooves cut on the outside of impeller shroud, and the suction performance was considerably improved by the booster.
