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
