Product Description
Product details
Features
  • Single seal
  • Balanced
  • Independent of direction of rotation
  • Stationary springs
  • Dual seals in tandem as well as back-to-back arrangements (also in combination with H10 seal)
Advantages
  • Safe operation (no fractures) because of seal face locking by square pin
  • Spring unit averted from the product so no sticking and clogging of the springs
  • Suitable for pressure reversals
  • Operation in vacuum without additional seat locking possible
  • No damage of the shaft by a dynamically loaded O-Ring
  • Small installation sizes
  • Best suitable for conversions, no adaptations of the pump
  • Insensitive to solid containing and abrasive media
  • Advantages of a balanced seal even with plain shafts
  • Insensitive to shaft movements because of the stationary design
Operating range
Shaft diameter:
d = 18 ... 100 mm (0.71" … 3.94")
Pressure: p1*) = 25 bar (363 PSI)
Temperature:
t = -40 °C ... +220 °C (-40 °F … 428 °F)
Sliding velocity: vg = 20 m/s (66 ft/s)
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 side.

Materials
Seal face: Carbon graphite resin impregnated (B), Silicon carbide (Q1)
Seat: Silicon carbide (Q1)
Secondary seals: FKM (V), NBR (P), FFKM (K), PTFE (T)
