Hydrotransport equipment of mining and processing plants has low operational reliability, insufficient service life due to intense hydroabrasive wear of the working surfaces of pipelines and pumping equipment, design flaws of some ground pump units and their operation. Significant hydroabrasive wear of the main structural element of the ground pump – impeller, causes additional disturbing dynamic forces, which leads to increased vibration of the unit and, therefore, to its premature failure. To date, insufficient attention has been paid to the impact of hydroabrasive wear of the impeller of ground pumps on the service life of their plants.The analysis of manifestation of cavitation wear of parts of the ground pump flow part is carried out, measures to reduce cavitation due to favorable conditions for the liquid flow into the pump and to reduce the vacuum gauge suction lift are outlined. A number of technological and constructive solutions are also proposed to reduce the harmful effects of cavitation.Materials for manufacturing parts of a centrifugal ground pump with high performance and service life are selected and analyzed. These alloys showed high corrosion resistance due to high chromium content.The ways of improving the design of centrifugal ground pump parts are outlined, which allows increasing the service life, creating an automated system for diagnosing the state of the structure as a whole
