The initial parameters of three required standard sizes of an improved hydraulic ram pumping unit have been determined: one standard size NUV-7-12 for watering pastures and two standard sizes NUV-17-20 and NUV-35-20 for irrigation of land during water lifting from watercourses powered by water energy, developed at KazNARU during research on applied research and DP21682075 project "Pumping units for lifting water from watercourses powered by water energy" through JSC "Science Foundation" of the Ministry of Education and Science of the Republic of Kazakhstan (Contract No. 102 dated 11/10/2023). Formulas are given for determining the initial parameters of an improved hydraulic ram pumping unit: supply, pressure and water flow to drive a pumping unit for watering pastures and irrigation of land plots of peasant and farms of the agro-industrial complex of the Republic of Kazakhstan, and their numerical sizes for each standard size are determined.
