The Teflon Bellow Mechanical Seal is specifically designed for extreme corrosive chemical applications, including concentrated acids, salts, strong oxidizing and reducing agents, and chemically active organic compounds. All components in contact with the sealed media are made from chemically inert materials, such as PTFE (Teflon) and other high-performance fluoropolymers, ensuring excellent chemical resistance.
Feature;
- Single seal
- Pusher type
- Unbalanced design
- Externally mounted
- Rotary multi spring type
- Low cost & mass produced
- Independent of the direction of rotation
