Annotation This paper focuses on the study of the influence of the vortex stage impeller blades angle installation in a centrifugal vortex pump. The mathematical model used in the numerical modeling is described. The 3 variants models of working regenerative impeller with different installation angles are considered. The paper shows the influence of the angle of the blades on the energy characteristics. The evaluation criteria were pressure, hydraulic efficiency and manufacturability. The results obtained during hydrodynamic modeling are presented in the form of velocity distribution vector fields. This paper will be of interest to specialists in the field of designing vortex hydraulic machines.
