In industries such as chemical processing, pharmaceuticals, electroplating, metallurgy, and environmental protection, handling highly corrosive acids and alkalis has always been a major challenge for fluid transfer systems. With advances in material technology, the PTFE-lined self-priming pump has become a core component in modern industrial processes — offering superior corrosion resistance, excellent self-priming performance, and reliable long-term operation.
1. What Is a PTFE-Lined Self-Priming Pump?
A PTFE-lined self-priming pump features a metallic casing lined with PTFE (polytetrafluoroethylene) or F46 fluoroplastic on the inside. This design perfectly combines the mechanical strength of metal with the chemical stability of fluoroplastic, making the pump capable of withstanding a wide range of strong acids, alkalis, oxidizers, and organic solvents. It provides truly comprehensive corrosion protection for demanding chemical environments.
2. Superior Corrosion Resistance and Self-Priming Performance
PTFE material is renowned for its near-universal chemical resistance. Whether dealing with sulfuric acid, nitric acid, hydrochloric acid, hydrofluoric acid, chlorides, or oxidizing liquids, a PTFE-lined self-priming pump delivers consistent performance without degradation. Once primed, the pump can automatically draw liquid during operation — no need for repeated filling or bottom valves — greatly enhancing efficiency and convenience.
3. Wide and Reliable Applications
Chemical & Fine Chemical Industry – Transfer of acid, alkali, and solvent-based liquids;
Pharmaceutical & Pesticide Production – Transfer of raw materials and corrosive waste liquids;
Electroplating & Surface Treatment – Circulation of corrosive liquids and waste solutions;
Environmental Protection Projects – Handling of acid wastewater, neutralizing agents, and fluorine-containing effluents.
4. Key Advantages of PTFE-Lined Self-Priming Pumps
✅ Exceptional corrosion resistance against almost all chemical media;
✅ Strong self-priming ability for easy and quick operation;
✅ High mechanical strength and extended service life;
✅ Leak-free and environmentally friendly operation, ensuring workplace safety.
