Description
The pump’s design and material selection fully address material strength, corrosion, wear, heat resistance, thermal conductivity, cooling, and lubrication issues under conditions of high flow rate, high head, and elevated temperatures. Incorporating a novel cavity design concept, secondary convection air cooling structure, specialized heat shielding devices, and a reliable lubrication system, this pump series achieves enhanced efficiency, reliability, and performance while delivering greater energy savings. The product line holds multiple invention and utility model patents.
Our high-temperature molten salt pumps are suitable for: solar thermal power generation, nuclear power, molten salt thermal storage, waste heat recovery, alumina production, chlor-alkali (caustic soda flakes, granular caustic soda), benzene blending, isobutylene blending, acrylic acid, fluorochemicals, refrigerants, melamine (Tsinghua gas-phase quenching process, OTC high-pressure process, DSM polycyanamide units), and organic chemical industries.
Our company possesses a complete production process encompassing 3D rapid scanning, 3D printing technology, alloy casting, machining, and high-temperature testing. Whether for experimental projects requiring compact pumps or large-scale engineering applications demanding heavy-duty units, we deliver molten salt pumps tailored to specific needs—operating at temperatures ≤300°C, ≤600°C, or ≤850°C. Our pumps feature lengths up to 18 meters and head capacities reaching 350 meters. We offer multiple materials for wetted components to withstand diverse high-temperature media, including nitrates, carbonates, fluorides, and more.
