The influence of vortex generators mounting in the wet part of a centrifugal pump on its characteristics was investigated. Dependents of efficiency, cavitation characteristic, head and capacity are given. The vortex generators were mounted on the front edges of suction sides of the blades, where stall occurs, and a vortex is formed. The simulation results were compared with the characteristics obtained for the usual optimized flow part of the pump.
