Abstract：A low specific speed pump,which was designed by the methods of enlarging flow rate,was tested for its cavitation feature and the outlet pressure fluctuating characters on a closed test rig.The outlet pressure fluctuating characters were determined by the root mean error.The relationship between the net positive suction head and the pressure pulsation of the pump outlet was set up by the experimental data and then compared with the traditional methods.The results showed that the two parts have close correlation,and the pressure pulsation can be use to monitor the incipience and the development of the cavitation.
