N2 - In order to study the behavior of severe cavitation erosion occurring in a typical centrifugal pump with a high specific speed of Ns = 300 (m, m3/min, rpm), the high-frequency vibrations and noises due to such cavitation erosion are systematically investigated under various test conditions. The present erosion tests are carried out using three-dimensional impellers made of aluminum alloy. In a field where the flow rates as well as NPSH are low, the vibrating accelerations and the acoustic power sharply increase, so that severe erosion takes place in this field. A large difference in flow pattern is clearly observed with respect to the flow rate.
