This study aims to optimize energy efficiency in industrial centrifugal pump systems using Variable Speed Drive (VSD) technology. The research employs an experimental quantitative approach using a centrifugal pump test rig equipped with VSD to analyze the relationship between rotational speed, flow rate, head, and power consumption. Data were collected under multiple steady-state operating conditions with varying pump speeds. Performance analysis is conducted using pump affinity laws and efficiency equations to evaluate energy usage and hydraulic performance. The results indicate that VSD operation significantly improves energy efficiency compared to fixed-speed operation while maintaining required flow conditions. The proposed operational framework provides an effective strategy for reducing energy consumption in industrial pumping systems and supports sustainable energy management practices.
