BW Series Jacketed Chemical Pump – High Temperature Jacketed Centrifugal Pump for Viscous & Crystallizing Fluids

Working Principle This pump is a single-stage, single-suction centrifugal pump with an added jacketed insulation layer around the casing. Fluid enters through the axial inlet, gains kinetic energy from the high-speed rotating impeller, and discharges through the radial outlet. The external heating jacket allows steam, hot water, or thermal oil to circulate and maintain the fluid at the required temperature, preventing crystallization or solidification. Axial thrust is balanced by balance holes and back vanes. The shaft seal can be configured with packing or mechanical seals to ensure reliable sealing under high-temperature conditions. Applications 1. Petrochemical Industry – Ideal for transferring crude oil, heavy oil, residual oil, asphalt, paraffin, and other heat-traced chemicals. Widely used in refineries and chemical plants for material transfer and intermediate product handling. 2. Fine Chemicals & Organic Synthesis – Suitable for pumping phenol, phthalic anhydride, maleic anhydride, fatty acids, resins, and other high-freezing-point organic media, ensuring no crystallization during transfer. 3. Chemical Fiber & Textile Industry – Used for caprolactam, polyester chip melts, viscose, and other polymer materials and high-temperature liquids. 4. Food & Pharmaceutical Industry – Ideal for transferring syrups, oils, gelatin, medicinal liquids, and other temperature-maintained fluids, meeting sanitary requirements for heated transfer applications.
