IHF Fluorine-Lined Chemical Pump Overview The IHF fluorine-lined chemical pump is a centrifugal pump designed for handling highly corrosive, toxic, or hazardous fluids in industrial applications. It features a fluoroplastic-lined casing and impeller, providing exceptional resistance to aggressive chemicals such as strong acids, alkalis, and organic solvents. This pump is widely used in industries like chemical processing, pharmaceuticals, electroplating, and wastewater treatment, where durability and leak-proof performance are critical. Design and Construction The IHF pump is constructed with a metal outer shell (typically cast iron or stainless steel) lined with fluoroplastic materials such as PTFE (polytetrafluoroethylene), FEP (fluorinated ethylene propylene), or PFA (perfluoroalkoxy). The lining covers all wetted parts, including the impeller, volute, and shaft sleeve, ensuring complete corrosion protection. The pump employs a rear pull-out design, allowing easy maintenance without disconnecting the piping. Key components include: - Fluoroplastic-Lined Impeller: Ensures resistance to chemical attack while maintaining hydraulic efficiency. - Mechanical Seal: Available in various configurations (single, double, or cartridge seals) to prevent leakage and extend service life. - Closed Motor Connection: Complies with explosion-proof requirements for hazardous environments. Performance Characteristics - Flow Rate: Typically ranges from 3.2 to 100 m³/h. - Head: Up to 50 meters, suitable for low-to-medium pressure applications. - Temperature Range: -20°C to 120°C (higher with specialized materials). - Pressure Rating: Up to 1.6 MPa. Advantages 1. Corrosion Resistance: Ideal for acids (e.g., sulfuric, hydrochloric), alkalis, and oxidizing agents. 2. Leak-Free Operation: Advanced sealing systems minimize fluid leakage. 3. Low Maintenance: Rear pull-out design simplifies repairs. 4. Versatility: Compatible with diverse chemicals and industrial processes. Applications - Transferring corrosive liquids in chemical plants. - Circulating aggressive media in plating or pickling lines. - Handling solvents or high-purity fluids in pharmaceuticals. Conclusion The IHF fluorine-lined chemical pump combines robust construction with superior chemical resistance, making it a reliable choice for demanding industrial environments. Its design prioritizes safety, efficiency, and longevity, ensuring optimal performance in corrosive fluid handling.
