The authors investigate the inner flow within the vortex pump impeller. Starting with the measured inner flow field within the impeller and pressure on the blade surfaces never touched by the previous researchers. And in cooperation with the measured results of inner flow within the chamber obtained by other researchers, a flow pattern is established and used to calculate flow field within the vortex pump impeller. As application of boundary elements method to its calculation) a method is suggested for calculating the fully three-dimensional potential flow field within vortex pump impeller. A comparison of the calculated and measured results showing the same tendency between calculated and measured results of velocities, and a good agreement between calculated and measured values of pressure on blade surfaces.
