Constant speed pumps are commonly used in pressurised water distribution systems due to their simplicity. Constant-speed pumps, on the other hand, have a hard time dealing with changing water flow requirements. When the discharge demand differs from the design discharge, the required demand (discharge and head) can be met simply by changing the pump speed without affecting the rest of the system. In this study, the efficiency of stations with variable speed pumps outperformed stations with fixed speed pumps in all operating situations. Variable speed pumps not only improve efficiency, but they also help satisfy water demands. The use of variable speed pumps in pressured irrigation systems is studied in this study. Near Tabriz, Iran, the chosen pump station has an actual sprinkler irrigation system with three lateral lines and a 600-meter main pipe. The main pipes have diameters of 8 and 6 inches. According to the research, using a variable speed pump improves average pump efficiency by 18.7%. In addition, the variable speed pump technology saves 57.6% on electricity as compared to a fixed speed pump. As a result, in pressurised systems, variable speed pumps should be used. This study adds to the body of knowledge by providing step-by-step calculations for sprinkler irrigation system design. This understanding will aid engineers who are unfamiliar with the commutation technique.
