Abstract The present state of research on flow induced vibration and noise of centrifugal pumps was introduced. Based on the virtual instrument data acquisition system and a routine pump test system, a closedloop test rig was established for measurement of flow induced vibration and noise in centrifugal pumps. A synchronous acquisition was realized for pump performance parameters and flow induced vibration and noise signals.  A singlestage, endsuction centrifugal pump with 5 blades, whose specific speed was 93, was chosen as the experimental model. The additional impellers respectively with 4, 6 and 7 were made and tested in the same volute. The performance of pumps with those four impellers were measured in the whole flow rate, the vibration and noise signals were recorded and processed as well. The experimental results show that the highest vibration intensity is observed in the pump with 5 blades. With increasing flow rate, the vibration intensity level keeps constant initially and then significantly rises. The frequency of noise issued from the pumps mainly was in the range of 0-2 000 Hz. With increasing number of blades, the peak shaft frequency augments gradually at small flow rates. Those outcomes will be instructive and helpful for establishing a hydraulic design method to ensure centrifugal pumps with a low level of flow induced vibration and noise. 
