Cavitation in centrifugal pumps is regarded as the main cause of deterioration of important parts of the pump, including impellers and volute. In order to examine this phenomenon, first a two-stage BB2 pump of the API design was experimentally investigated in terms of head and flow rate in single-phase flow and flow with cavitation, then the results were compared to those of the model created in the ANSYS CFX software environment. In addition, the...
