Molten-Salt Circulation Pump for Evaporation-Crystallization & Specialty Chemical Manufacturing

Working Principle The top-mounted motor drives the submerged impeller via an extended shaft. The spinning impeller generates axial thrust to maintain large-volume circulation of hot process media. With its vertical long-shaft design, the pumping end sits submerged inside the process tank, cutting down complex inlet piping. Optimized hydraulics lessen particle-impact wear, and the heavy-duty shaft assembly keeps vibration low under high-temperature conditions to support long‑term non-stop operation. Applications Specialty Chemical Plants: Handles continuous process circulation for phthalic anhydride, maleic anhydride, acrylic acid, fumaric acid and melamine manufacturing, common across US chemical batch and continuous production facilities. Refrigerant & Light-Metal Processing: Supports molten‑salt heat‑transfer loops for refrigerant production and aluminum-magnesium alloy processing plants throughout North America. Polymer & Rubber Manufacturing: Moves hot salt-rich, crystal-prone feeds including sodium salts, potassium salts and caustic solutions for rubber compounding and plastic resin production lines. Thermal-fluid Process Systems: Fits evaporation and crystallization units where high-temperature brines and alkaline fluids require steady large-flow recirculation.
