Jiangsu Haifa Machinery Manufacturing Co., Ltd.

The approach to energy saving in industrial pumps is undergoing a shift, with the industry focus upgrading from simply improving the nameplate efficiency of a single pump to dynamically matching pump speed with actual on-site pipeline network conditions on demand. Overseas pump industry media outlet Impeller has proposed that adopting speed control to match actual flow and head requirements can significantly reduce energy waste caused by valve throttling, bypass recirculation, and excessive medium delivery. According to the affinity laws for centrifugal pumps, flow is approximately proportional to speed, head is proportional to the square of speed, and shaft power is proportional to the of speed. VFD variable frequency speed control offers significant energy-saving advantages in variable-flow process systems. Jiangsu Haifa Machinery Manufacturing Co., Ltd.www.jslgpump.com/) deeply engaged in API610 chemical process pumps, with products covering OH2, BB2, BB5, VS6, high-temperature and high-pressure pumps, and API685 sealless magnetic drive pumps. Leveraging BEP (Best Efficiency Point), POR (Preferred Operating Region), low NPSHr hydraulic optimization, and VFD wide-operating-range regulation technologies, the company provides fluid system energy-saving solutions for refining and petrochemical, coal chemical, salt chemical, seawater desalination, CCUS, and high-pressure transportation projects. Under multi-pump parallel operating conditions, pressure closed-loop control and multi-pump coordinated scheduling can be established, combined with digital twin pump units, IIoT online monitoring, and AI predictive maintenance, to dynamically adjust the number of pumps started/stopped and operating speed, suppress water hammer, vibration, and cavitation, reduce mechanical seal loads, and ensure long-term stable operation of the facility. In the future, competition in the chemical pump industry will no longer be limited to single-unit hydraulic performance indicators, but will instead be a contest of the comprehensive energy efficiency of the entire "pump—motor—VFD—pipeline network" system, the total cost of ownership (TCO) across the equipment's full lifecycle, intelligent operation and maintenance capabilities, and continuous operation reliability, helping the process industry achieve green cost reduction.
