High-Temperature Concentrated Sulfuric Acid Pump

This series of pumps is suitable for drying and absorption circulation systems in sulfuric acid production, as well as for transferring finished concentrated sulfuric acid. They are designed for conveying temperatures t ≤ 110°C and sulfuric acid concentrations ranging from 93% to 98% concentrated sulfuric acid. Building upon this foundation, Additionally, to support and adapt to domestically produced HRS low-temperature waste heat recovery systems, our company has successfully developed ultra-high-temperature concentrated sulfuric acid pumps specifically designed for HRS systems, capable of operating at temperatures ranging from 190°C to 220°C. These pumps incorporate our patented secondary convection energy-saving air cooling technology to ensure bearings operate unaffected by high-temperature medium conduction. Furthermore, we have developed concentrated sulfuric acid pumps with a sulfuric acid concentration of 104% to 105% (fuming sulfuric acid), featuring dry gas seals at the packing area to prevent SO₃ gas overflow. 190–220°C ultra-high-temperature concentrated sulfuric acid pumps. Our patented secondary convection energy-saving air cooling technology ensures bearings operate unaffected by high-temperature medium conduction. Furthermore, our joint material R&D facility with the Chinese Academy of Sciences’ Institute of Metal Materials provides customers with pumps, pipes, plates, castings, forgings, and related products made from various acid-resistant alloys including 20# alloy, 20CB3, 310S, 904L, SS920, C8, and high-silicon stainless steel. 310S, 904L, SS920, C8, high-silicon stainless steel, and other acid-resistant, corrosion-resistant alloy materials for pumps, pipes, plates, castings, forgings, and related products. We also undertake the development of pumps for special operating conditions and material requirements.
