description: The article presents the results of research devoted to the design and numerical calculation of a low-flow high-head centrifugal pump with Barsketype impeller using computer simulation methods. The main features of fluid flow hydrodynamics, as well as the influence of a number of design geometry on the energy and cavitation characteristics of the pump, are found. The focus is on the analysis of the influence of the end gap between the impeller blades and the casing, as well as the cavitation qualities of the pump. The issue of cavitation qualities of a pump with different geometry of the pump inlet area investigated. In addition, a comparison of different outlet types and the selection of the best option provided. Analysis of the importance of installing the ribs in the suction line, taking into account the vortex structure of the flow in the impeller, was carried out. In addition, the results of changes in energy characteristics when pumping a working fluid with high kinematic viscosity are given.
