Teflon Bellow Mechanical Seal

The Teflon (PTFE) bellow mechanical seal is designed for highly corrosive and aggressive media where standard elastomers cannot perform. With excellent chemical resistance and a non-metallic, non-stick surface, it is ideal for pumps handling acids, alkalis, solvents, and food-grade fluids.
