With the official implementation of GB 19762-2025 "Minimum Allowable Values of Energy Efficiency and Energy Efficiency Grades for Centrifugal Pumps" on March 1,2026, industrial pumps are entering a new stage centered on High Efficiency Pump, Best Efficiency Point (BEP), Life Cycle Cost, and Efficiency, moving beyond merely "meeting flow and head requirements." The new standard covers clean water centrifugal pumps and some petrochemical centrifugal pumps, while simultaneously promoting the upgrading of energy-saving certification for chemical pumps For petrochemical, coal chemical, new materials, and energy projects, true high efficiency is not simply about improving nameplate efficiency, but about making the rated operating condition as close to BEP as possible, while comprehensively verifying NPSHr, suction specific speed, system resistance, and variable-condition operating range. Jiangsu Haifa Machinery Manufacturing Co., Ltd..jslgpump.com has established a product system covering API 6101/OH2, BB1–BB5, VS series, magnetic drive pumps, high-temperature and high-pressure chemical pumps, forced circulation pumps, capable of hydraulic matching for different media, temperatures,, and flow ranges. Jiangsu Ligong's 202 API 610 13th Edition drives process pumps toward reliability, NPSH control, mechanical integrity, and traceable design. Meanwhile, Standardized Pump Selection, Hydraulic Model Optimization, Modular Pump Skid, and Shorter EPC Delivery Cycle are becoming new professional terms in engineering projects. For low specific speed, high pressure, multistage, high temperature, low temperature, and easily vaporizing media, pump selection can no longer rely solely on Q-H; it must simultaneously evaluate POR, AOR, suction performance, and long-term operational stability. Digitalization is pushing pumps from "passive maintenance" toward Condition Monitoring and Predictive Maintenance. The latest research in 202 is applying Digital Twin, multi-sensor data, vibration, current, pressure, and temperature to centrifugal pump fault identification, cavitation warning, and health state assessment. Jiangsu Haifa combines high-efficiency hydraulic models, API 610 standardized design, special materials, online monitoring, and full life cycle services, upgrading process pumps from single pieces of equipment to verifiable, monitorable, and optimizable delivery systems, providing more reliable and efficient domestically produced pump solutions for refining, coal chemical, new energy, offshore engineering, and new materials facilities.
