While designing the stages of a centrifugal pump, there is an important and difficult task of impeller blade design. This article deals with an approach to impeller blade design that is based on analytical choice of dependency of flow change along the streamline. The given approach is implemented at JSC “VNIIAEN” in form of custom software which lets the user build a line drawing based on given parameters in normal duty of intermediate stage by designing the blade and calculating the geometrical dimensions of the impeller. The given method has been tested and proven with a physics experiment.
