As a result of the research, it was found that the blades of the working impellers of the pumps are eroded at the inlet and outlet. Based on software studies, the points of erosion caused by cavitation and sand particles at the entrance of the impeller and the points of operation of the impeller under heavy load have been determined. The operating points under heavy load are compared with working impellers in nature. After comparison with software developments, it is determined that they are compatible with working impellers in natural conditions. The following impeller model is recommended to reduce cavitation and erosion processes in the impeller (Figures. 6, 10). The recommended impeller is shown in the inlet of the impeller to free water entry, prevent water shortage, and reduce the level of cavitation. (Figures 6, 10, 11). The ingress of water into the impeller is freed, the continuous movement of water is restored, and the methods of preventing the processes of decay and holes formed in the impeller are given. Recommended methods of significantly reducing the level of wear in the input and output parts of the impeller are given.
