The development of hydraulic technologies requires the use of new structural materials. The study used the main provisions of the theory of positive displacement hydraulic machines and hydraulic drives and methods for their solution using multiphysics software. The article presents the results of a comparative analysis of the performance of plunger pairs made of synthetic corundum in hydraulic machines of power drives. The effect of using synthetic corundum in hydraulic power drives is determined. Analysis of the obtained results makes it possible to conclude that when using synthetic sapphire as a plunger material, taking into account the preservation of structural geometry, maximum stresses are reduced by 4.7%, contact stresses by 4.7%, and deformation by 44%, with a decrease in weight by 49%.
