In this paper the flow field in a diffuser pump stage consisting of a centrifugal impeller and a radial diffuser is investigated by using unsteady computations. The time-averaged unsteady results are used to understand the main sources of loss in the stage. Then 3D inverse design method used to redesign the impeller and diffuser blades in order to improve the stage efficiency.
