Chemical High-Temperature New VS4+ Pump
To complement and adapt to the HRS low-temperature waste heat recovery system, our company has successfully developed a high-temperature concentrated sulfuric acid pump specifically designed for the HRS system, capable of handling temperatures ranging from 190 to 220°C.
Description
To complement and adapt to the HRS low-temperature waste heat recovery system, our company has successfully developed a high-temperature concentrated sulfuric acid pump specifically designed for the HRS system, capable of handling temperatures ranging from 190 to 220°C. This pump incorporates our patented secondary convection energy-saving air cooling technology, ensuring that bearings operate without being affected by heat conduction from high-temperature media.
Use of materials
Our company has established a joint materials R&D center with the Institute of Metal Research, Chinese Academy of Sciences. 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 requiring special materials and specifications for demanding operating conditions.
Scope of application
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 t ≤ 110°C and sulfuric acid concentrations of 93% to 98% concentrated sulfuric acid. Furthermore, a 104% to 105% with sulfuric acid concentrations ranging from 93% to 98%. Building upon this foundation, 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 S₂O₃ gas.
