The impact of polymer additives on methods of reducing head loss when overcoming hydraulic resistances in pumping systems and their regime for the needs of the agro-industrial complex is considered. The results of experimental studies of work on an industrial stationary cantilever centrifugal pump, brand 2K-6, by closing the valve on the pressure pipeline and starting the pump unit in operation, according to and after the introduction of polymer additives into the water, are presented. During the operation of the pumps, a high molecular weight polymer was added to the water at a dose of 0.01%. After the pump set went into normal operation mode, changing the degree of opening of the valve, five arbitrary water pumps with and without impurities were set, starting from zero and bringing the supply to the maximum value, that is, ten experiments were performed. For each variant of the pump supply, the readings of the vacuum gauge, manometer and ammeter were taken, the readings of the supply value in each experiment were selected from the triangular measuring spillway and all the readings were entered in the relevant tables of experiments. A comparison of the operating characteristics of pumps pumping water with the addition of PAA with the passport characteristics showed an improvement in the characteristics of the pumps, namely, the pump delivery Qn increased by approximately 30%, and the efficiency increased by 10%. The analysis of research makes it possible to conclude that the use of polymer additives increases the efficiency of pump installations and significantly reduces their energy consumption. In addition, the use of polymers makes it possible to obtain the specified operating parameters of the pump without increasing the diameter of the pipeline.
