Description
Non-contacting Secondary Containment Seal
The 28SC is a gas-lubricated, non-contacting secondary containment seal, which is applied as a component of a multiple seal cartridge. Secondary containment seals are intended to contain primary seal leakage in the event of a primary seal failure. Patented bi-directional seal face pattern provides non-contacting operation, preserving the seal faces until the seal is required to seal primary seal leakage.
Features
California Residents: Proposition 65 Warning
- Unbalanced primary ring and a very short design length.
- The design of the secondary O-ring enables reliability in a vacuum environment — a circumstance common in Plan 02 containment chamber designs.
- Non-contacting operation ensures like-new seal faces until primary seal leakage is encountered, where the 28SC operates as a full face contacting containment seal.
