Using numerical simulation, the authors have got the velocity distributions along the radius of the flow passage of the investigated stage at near-optimum modes. Pressure distributions on the blade surfaces at various pressures at the impeller inlet of the considered stage were also obtained. The article presents the results of testing of the pump using an experimental rig, together with comparison of the experimental and simulated performance curves. Numerical research was carried out using the ANSYS CFX software. Basing on the results of the research, the conclusion concerning expediency and prospects of application of small-sized axial-flow stages in borehole pumps for water supply are made, considering their advantages in comparison with mixed-flow stages.
