New VS4+ Sulfuric Acid Pump
To complement the HRS cryogenic waste heat recovery system, our company has successfully developed a high-temperature concentrated sulfuric acid pump specifically designed for HRS systems, capable of handling temperatures ranging from 190 to 220°C. This pump incorporates our patented secondary convection energy-saving air cooling technology, ensuring bearings operate without being affected by heat transfer from high-temperature media.
We provide customers with pumps, pipes, plates, castings, forgings, and related products made from various acid-resistant and corrosion-resistant alloy materials, including 20# alloy, 20CB3, 310S, 904L, SS920, C8, and high-silicon stainless steel. We also undertake the development of pumps for special operating conditions and specific material requirements.
This series of pumps is suitable for drying and absorption cycles in sulfuric acid production, as well as for conveying finished concentrated sulfuric acid. They are designed for temperatures ≤110°C and sulfuric acid concentrations ranging from 93% to 98%. Additionally, a pump for 104% to 105% fuming sulfuric acid has been developed. A dry gas seal device has been installed at the packing area to prevent the upward leakage of SO₃ gas.
