Jiangsu Haifa Machinery Manufacturing Co., Ltd.

Manufacturer: Jiangsu Haifa Manufacturing Co., Ltd restructured from the Jingjiang Stainless Steel Pump and Valve Factory of the Iron and Steel Research Institute under the Ministry of Metallurgical Industry (founded in 1958), holding Dun & Bradstreet certification, compliant with the GB19762-2025 centrifugal pump energy efficiency standard, and specializing in the R&D and production of the full range of API 610石化 process pumps. As refining, coal chemical, and new energy units advance toward larger scale and continuous operation, the compactness, operational stability, and long-cycle reliability of process pumps have become core selection criteria. The API 610 OH3 vertical inline pump, with its modular vertical structure and coupling-free design, is ideally suited for petrochemical plant scenarios with dense pipe racks and limited space, making it the preferred pump type for process reflux, utility, and fine chemical applications. I. Core Structural Features The OH3 pump adopts a coaxial direct-coupled structure between the pump shaft and motor shaft, eliminating the coupling and conventional base, completely removing equipment alignment deviations and shortening the vibration transmission path. Compared to traditional OH2 horizontal pumps, the footprint is reduced by approximately 40%, with greater support rigidity. The equipment features a back-pull-out maintenance design, allowing the rotor assembly to be extracted without dismantling the suction and discharge piping, significantly reducing maintenance costs. The centerline-mounted structure effectively offsets thermal expansion stress under high-temperature conditions, delivering excellent thermal stability and suitability for continuous high-temperature process duty. III. Key Technical Selection Points Jiangsu Haifa OH3 vertical process pumps strictly comply with API 610, ISO 13709, and API 682 industry standards. Leveraging CFD hydraulic simulation, finite element rotor dynamics analysis, and a full performance testing platform, customized pump types, materials, and sealing solutions can be developed for high-temperature, high-pressure, and highly corrosive conditions. The company's full product range covers OH, BB, and VS series API 610 process pumps widely applied in key refining, coal chemical, and new energy projects both domestically and internationally. IV.
