Dry-contacting Secondary Containment Seal – Type 48SC
Dry-running, contacting seals employ a technology based on careful material selection and precise control of contact forces. They are designed to operate dry, with the containment chamber between the seals being vented to a flare or vapor recovery system.
Product Description Type 48SC
Self-cooling Type 48SC Seals are full contact dry-running secondary containment seals. This breakthrough in dry tandem sealing requires no external lubrication system, reducing hazards from buffer fluid contamination and eliminating contaminated fluid disposal problems. Available in retrofit kits, these secondary containment seals can fit into existing cartridges.
- For service in chemical processing, cryogenics, offshore platforms, oil production and refining, petrochemical processing, pharmaceutical, and pipeline transmission
