Jiangsu Haifa Machinery Manufacturing Co., Ltd.

Jiangsu Haifa Machinery Manufacturing Co., Ltd. builds on the special corrosion-resistant alloy R&D and application foundation from the former Ministry of Metallurgical Industry system, combining material selection with process conditions to provide corrosion-resistant fluid transportation solutions across six major process modules. In dilute sulfuric acid and waste acid transportation sections,-resistant alloy chemical pumps can be matched according to H₂SO₄ concentration, temperature, Fe²⁺/Fe³⁺, TiO₂ particles, and crystallized salt conditions; in acid production, drying and absorption, and high-temperature acid circulation systems, high-temperature sulfuric acid circulation pumps, vertical acid pumps, and API 610 process pumps can be configured for Hot Acid Circulation and high-temperature concentrated sulfuric acid conditions in waste heat recovery systems, the focus is on solving material corrosion, NPSH margin, and continuous operation stability. In sulfuric acid process titanium dioxide production, titanium liquid concentration, waste acid pre-concentration, circulation, and MVR waste acid concentration have become important links for energy saving and acid resource reuse. For media with high salt content, easy crystallization, and easy scaling, Jiangsu Haifa can provide forced circulation pumps, corrosion-resistant centrifugal pumps, vertical submerged pumps, and special alloy process pumps, with material matching based on complex components such as high-temperature dilute sulfuric acid, 50%–60%ated acid, and ferrous sulfate. Jiangsu Ha Machinery Manufacturing Co., Ltd www.jslgpump.com Products cover API 610 OH1/OH2, BB series, VS series, high-temperature and high-pressure chemical pumps, corrosion-resistant magnetic drive pumps, forced circulation pumps, and special pumps, serving Sulfuric Acid Plants, Titanium Dioxide Sulfate Processes, Waste Acid Valorization, MVR Mechanical Vapor Recompression, Liquid Discharge (ZLD), and other facilities. Moving from single acid-resistant pump selection to collaborative design of "process medium—corrosion mechanism—special alloy—hydraulic model—sealing system—energy efficiency" is becoming an important direction for upgrading highly corrosive chemical facilities. Haifa hopes to provide more complete domestically produced fluid equipment solutions for acid production, titanium dioxide, metallurgy, chemical, and waste acid resource utilization projects by combining technology with process pump technology.
