The given work is devoted to the design of the flow path of a Ñantilever centrifugal pump according to the method of S. A. Gorgidzhanyan[9] and its numerical calculation using software. According to the methodological guidelines, the geometric parameters of the impeller and spiral outlet were calculated. A cylindrical blade system and a spiral outlet are designed. The anti-cavitation qualities of the pump were analytically evaluated. In the Solidworks program, 3D models of the impeller, spiral outlet and models of the corresponding flow parts were built, according to the previously calculated geometric parameters. Calculation grids of calculated elements were created, corresponding to the calculation being carried out. Numerical studies of the wheel and the entire flow path were carried out using a mathematical model and visu-alization of the results obtained, the calculation was carried out using the Ansys CFX software. Based on the calculation performed, the energy characteristics of the designed flow path were obtained. Theoretical drawings of the pump impeller and volute have been drawn up. Comparison of the results obtained with the requirements provided by the terms of reference.
