20M & LPT 20R
PTFE Bellow Seals for Extreme Corrosive Applications
20M & LPT 20R
Seal Series 20M & LPT 20R are designed for highly corrosive chemical applications, including concentrated acids, salts, strong oxidizing & reducing agents, and chemically active organic compounds. These seals ensure maximum chemical resistance by using chemically inert materials for all sealing components, while metallic parts are located outside the media.
- 20M Series: Features a Glass-filled PTFE face that is composite-molded with a highly flexible PTFE bellow, providing excellent resilience and chemical resistance.
- LPT 20R Series: Designed with replaceable sealing faces and a positively driven system. Integral lugs on the bellow ensure smooth torque transmission and enhance operational reliability.
These seals are single-acting, unbalanced and are independent of direction of rotation, making them a versatile choice for extreme corrosive applications.
