  • Seal faces are designed to be noncontacting during operation
  • Designed for environmental protection
    with high efficiency
  • Due to non-contacting design there is
    no friction on the seal faces and there is
    no heat generated at the seal or in the
    medium
  • Trouble free operations as complex
    components are not required to
    dissipate frictional heat
  • Differential pressure not required with hard / soft material combination
  • Conforms to containment seal in
    accordance with API 682
  • Chemical industry
  • Refining technology
  • Gases and liquids(single seals only gas)
  • Gases and liquids which must not get into the atmosphere (dual seal)
  • Gases not harmful to the environment (single seal)
  • Fans
  • Small steam turbines
  • Blowers
  • Roots compressors
  • Pumps
  • EN 12756
  • API 682 / ISO 21049
  • Seal face: Carbon graphite antimony impregnated (A),
    Silicon carbide (Q2),alternatively: Carbon graphite resin
    impregnated (B), Silicon carbide (Q1) Seat: Silicon carbide
    (Q1, Q2),
    Silicon carbide (Q19, Q29) with seal face in Q1 resp. Q2
  • Metal parts: CrNiMo steel (G)
  • Shaft diameter: d = 28 … 125 mm (1.10″ … 4.92″)
  • Pressure: p = 25 bar (363 PSI)
  • Temperature: t* = -20 °C…+170 °C (-4 °F…+338 °F)
  • Sliding velocity: v = 4 … 25 m/s (13 … 82 ft/s)
    * Depending on resistance of O-rings
  • Single and Dual seal configuration
  • Balanced design
  • For stepped shafts
  • Rotary unit with multiple springs
  • Designed to remain in closed position in
    the event of buffer pressure failure
  • Can accommodate reverse pressure
  • Gas-lubricated design
  • Gas grooves design is available in Vgrooves and U-grooves (independent
    of direction of rotation)
