Abstract: About 20% of global electricity production is consumed in rotary equipment to convey fluids such as water, gas, air, and other liquids, while the loss of energy consumption in this sector is more than 60%. The aim of this study was to evaluate different efficiencies in the pumping stations in the pressurized irrigation systems to address low energy efficiency issues in the pump stations and to develop solutions to enhance it. In this regard, the electrical efficiency, hydraulic efficiency, and mechanical efficiency were determined in the studied pump stations and they were used to determine total efficiency of each pump station. Pump station assessment tool (PSAT) software was used to model each station and predict annual energy consumption costs; furthermore, the potential of efficiency improvement was calculated. Results showed that the total efficiency of the studied pump stations ranged from 13 to 32% and averaged 24%. Factors, such as improper design, disproportion in terms of the operation conditions, and the design and improper operation, caused a drop in the efficiency of the pump stations. Also, the productivity of the energy consumption in the pump stations can be improved from 24 to 49% if these issues are tackled.
