摘要：

The paper presents and discusses experimental results regarding the effects of some volute tongue variations (more precisely the gap between the volute tongue and the impeller outlet) for a centrifugal pump, on the pressure fluctuations at the blade passing frequency. RMS values of pressure fluctuations at blade frequency measured in the discharge pipe of the tested pumps are also compared to the results of a computer code based on the theoretical model proposed by Simpson, Clarck and Weir.
