Abstract: The article considers a method for reducing hydraulic losses of a mine drainage centrifugal pump by adding second-row blades using the example of the CNS-300-120 impeller. The added blades cut down the energy losses by reducing the fluid turbulence at the impeller outlet. A model with two rows of blades is proposed. Computer modeling of the impeller and hydraulic fluid flow in the SolidWorks 2022 and the Ansys CFX software suites showed that the proposed method allows increasing the pressure at the operating point by 3.2–6.1% and the hydraulic efficiency by 3.0–6.0%. The method is most effective at the operating point with pressure values of H = 120 m and flow rate of Q = 300 m3/h in the working area. Outside the working area, the efficiency of the method decreases. Using the pump outside the permissible operating range is not recommended due to the risk of cavitating, overheating of the pumped medium, flow path, electric drive, and increased internal working fluid flow. This results in a significant reduction in the overall efficiency, which can lead to accelerated wear and failure of the pump.
