High-Temperature Molten Salt Pumps VS1, VS4, VS4+, VS5
This series of pumps employs our patented dynamic pressure liquid film support technology in its rotor design: utilizing deformation coordination and torque balancing techniques to analyze bearing loads under statically indeterminate support conditions, ensuring rotor components operate under liquid film support. Simultaneously, the sliding bearing material utilizes NH-8 high-temperature self-lubricating wear-resistant alloy, jointly developed by our company and the Institute of Metal Research, Chinese Academy of Sciences. This extends the product’s service life and operational cycle. Furthermore, the innovative cavity design concept, secondary convection air cooling structure, and specialized heat-blocking devices enhance and guarantee the efficiency, reliability, and performance of this pump series while delivering greater energy savings.

SDP is one of China’s earliest manufacturers of molten salt pumps. Since producing molten salt pumps for caustic soda in the 1970s, decades of R&D and expansion have broadened its applications to solar power generation, nuclear power, chlor-alkali, granular caustic soda, fertilizers, petrochemicals, alumina, refrigerants, phthalic anhydride, maleic anhydride, acrylic acid, fluorochemicals, melamine, and organic chemicals. The range of media has expanded from 450°C ternary salts to 560°C binary salts, 850°C fluoride salts, carbonates, 750°C molten magnesium slag, 400°C potassium hydroxide, 450°C modified sulfur, 400°C lead-bismuth alloys, and 420°C naphtha. The company also provides complete turnkey solutions including molten salt tanks, heaters, molten salt pumps and valves, and integrated automated skid-mounted services tailored to client requirements.
