Dry running emission
containment seal Y11
Features
- Stationary bellows seal
- Uniform seal face loading
- Independent of direction of rotation
- Special carbon grade for dry running capability
- Seal with low face pressure hence less seal face heat generation
- Compact design
- Mating ring with wave spring design
- Vibration dampener for bellows
- Outboard emission containment seal used along with inboard pusher or bellows seal
Advantages
- Narrow cross-section allows the seal fitment in narrow stuffing boxes
- Excellent dry running performance
- Longer seal life as less seal face wear
- Easy to install
- Safety seal to contain fugitive emissions
