  • Accommodates shaft deflections due to stationary design
  • Designed to handle media containing solids
  • O-ring is dynamically loaded to prevent shaft damage
  • Can operate under vacuum without locking the seat
  • Pumping device available for increased efficiency in circulation
  • Springs are product protected to avoid contamination
  • Compact installation design
  • Can accommodate reverse pressure
  • Chemical industry
  • Dirty, abrasive and solid containing media
  • Fugitive hydrocarbons
  • Refining technology
  • Sticky and stringy media
  • Water and waste water technology
  • Chemical standard pumps
  • Sewage pumps
  • EN 12756
  • Seal face: Carbon graphite resin
    impregnated (B), Silicon carbide (Q1)
  • Seat: Silicon carbide (Q1)
  • Secondary seals: FKM (V), NBR (P),
    FFKM (K), PTFE (T)
  • Springs: Hastelloy® C-4 (M)
  • Metal parts: CrNiMo steel (G)
  • Sizes: d1 = Upto 100 mm (Upto 4.000’’)
  • Pressure: p1*) = 25 bar (363 PSI)
  • Temperature: t = -40 °C .. +220 °C
    (-40 °F .. + 428 °F)
  • Speed = 20 m/s (66 ft/s)
  • Permissible axial movement: ± 1.0 mm
    *) Additional seat locking is not needed in
    vacuum operation. For operation under vacuum
    it is necessary to arrange for quenching on the
    atmosphere
  • Single seal configuration
  • Balanced design
  • Independent of direction of rotation
  • For plain shafts
  • Stationary design with multiple springs
