The article is aimed at increasing the efficiency of pasture water supply and irrigation of land plots of peasants and farms of the agro-industrial complex by improving the hydraulic ram pumping installation for lifting water from watercourses.Design and technological diagrams of two new standard sizes of hydraulic ram pumping units developed at Kazakh National Agrarian Research University for lifting water from watercourses for watering pastures and irrigating land plots are given, their distinctive features, novelty, brief design, principle of operation, which, compared to analogues, have advantages in improving energy performance.Comparative results of laboratory tests of the developed standard sizes of hydraulic ram pumping units are given and the advantage of the improved standard size is proven.The authors proposed a design and technological scheme of a hydraulic ram pumping unit.A graph of the results of laboratory tests of two standard sizes of a hydraulically driven pumping unit in accordance with pressure dependencies has been obtained.As a result of the performed analyses and research work, various variants of the standard size of hydraulic ram pumping units have been developed, which have high reliability and convenience and ease of maintenance, increased energy performance.The scheme of the hydraulic ram pumping unit developed by the authors makes it possible to increase the efficiency of the organization of water supply and thereby save fuel and energy resources.With the help of laboratory tests on a test bench, a comparative analysis of the main parameters of the performance indicators of the developed standard sizes of hydraulic ram pumping units was performed.
