In the article, the characteristics of the function of temperature difference of a working fluid at the inlet and outlet of gear pumps with different efficiency and at different pressures are theoretically and experimentally investigated. A method is proposed for determining the efficiency of pumps during its operation at variable pressure, based on the hypothesis that the performed useful work of the pump is characterized by the area under the pressure curve, and the lost energy is the area under the temperature difference curve.
