The main element of the hydraulic system is the pump, the reliability of which largely determines the reliability parameters of the entire hydraulic system. To ensure a high level of pump quality, it is necessary to carry out tests at different stages of production: design and prototype development, construction modernization, and development of new pump models. Since most of the time is spent on testing, the urgent task is to reduce testing time and improve the quality of hydraulic equipment. This work aims to evaluate the factors determining pump longevity while ensuring the equivalence of accelerated and long-duration resource testing of pumps. The reduced wear of parts should be used to compare the technical condition of pumps subjected to accelerated and long-duration tests. The effect on the wear of the increase in the friction path per unit of time during accelerated tests must be considered. When comparing pumps that have undergone accelerated and long-duration tests, there will be some discrepancy in the parameters compared, the extent of which is used to conclude a positive or negative test result. A positive result of the conducted tests can be considered if none of the specific types of failure occurred during the testing process and if no fundamentally new defects are found during the examination of the developed pump. This methodology can guide accelerated tests of axial piston pumps: regulated and non-regulated with valve distribution at 320 bar, regulated pumps with end distribution at 200 bar, and regulated pumps with end distribution at 160 bar.
