Abstract During the work considered questions of the occurrence of cavitation in hydro abrasive flows, which can lead to a rather complex phenomenon that is difficult to understand the essence of this process. Today, the wear of the working bodies of centrifugal and axial pumps, depending on the mode of their operation has not been learned much, and there has been developed a technique for selecting operating modes, taking into account the wear of their parts. Also, the results of complex laboratory and field studies on the intensity of wear of the flow elements of centrifugal and axial pumps are presented. It has been established that the alternating, pulsating load leads to an increase in the force of interaction of the hydro abrasive flow with the camera surface and increases its wear by 10 %, and also reduces the capacity of the pumping unit to 9%.
