Abstract: With the global energy transition and the advancement of the "dual carbon" goals, energy conservation in industrial pump systems has become a critical component of green manufacturing. As key energy-consuming equipment in industrial installations, centrifugal pumps can effectively reduce Life Cycle Cost (LCC) through hydraulic optimization, high-efficiency motor matching, and intelligent operation management, promoting the low-carbon development of industries such as petrochemicals, new energy, and environmental water treatment. The national standard GB 19762-2025, "Minimum Allowable Values of Energy Efficiency and Energy Efficiency Grades for Centrifugal Pumps," released in 2025, will take effect on March 1, 2026, replacing GB 19762-2007 and GB 32284-2015. It introduces new requirements for centrifugal pump energy efficiency grades, calculation methods, and test evaluation, covering clean water centrifugal pumps and certain petrochemical centrifugal pump products. High-efficiency design has become the development direction for industrial pumps. In the international pump industry, Energy Efficiency, High Efficiency Pump, and Variable Speed Drive (VSD) have become key technical directions for green factory construction. The International Energy Agency (I) points out that improving motor system efficiency and optimizing the operation of equipment such as pumps and fans are important measures for industrial energy conservation, and digital monitoring and intelligent control technologies are further enhancing equipment energy utilization. High-efficiency centrifugal pumps rely not only on high-efficiency impeller design but also need to combine: CFD flow field analysis (Computational Fluid Dynamics), three-dimensional hydraulic model optimization, low-pulsation impeller design, IE5 high-efficiency motor matching, and intelligent variable frequency drive (VFD), thereby improving the overall efficiency of the pump unit by reducing hydraulic losses and minimizing cavitation risk. API610 chemical process pumps support green industry. In the fields of petrochemicals, new energy materials, coal chemicals, and environmental protection engineering, high-reliability process pumps must simultaneously meet the requirements of efficiency, safety, and-term stable operation. Jiang Haifa Machinery Manufacturing Co., Ltd. (www.jslgpump.com), relying on the API610, API682, and API685 standard systems, professionally manufactures OH1, OH2, OH3, OH6, BB series, and VS series chemical process pumps, with products covering high-temperature high-pressure, corrosive, and special media conveying conditions. To meet the needs of green factory and zero-carbon factory construction, Haifa Machinery provides energy-saving fluid transfer solutions for petrochemical units, industrial circulating water systems, and new energy projects by optimizing pump hydraulic performance, improving mechanical efficiency, and matching high-efficiency motors. In the future, with the in-depth implementation of the GB 19762-2025 standard, high-efficiency, intelligent, and low-life-cycle-cost centrifugal pumps will become essential equipment for industrial energy conservation upgrades.
