Pump sump is an important part of pump station its performance influences the flow condition in the pump and even the total performance of the pumping system. In order to study the flow in an open pump sump the Two-dimension PIV system was used. Flow velocity, flow streamlines, turbulence intensity and vorticity can be obtained from the PIV data. The critical velocities for vortex inception have also been measured in this paper. Analyzing those parameters, the flow performance of the sump with special structure was found then the best condition could be chosen basing on the experiments.
