HJ92N

Features

  • For unstepped shafts
  • Single seal
  • Balanced
  • Independent of direction of rotation
  • Encapsulated rotating spring

Advantages

  • Especially designed for solids containing and highly viscous media
  • Springs are protected from the product
  • Rugged and reliable design
  • No damage of the shaft by dynamically loaded O-Ring
  • Universal application
  • Variant for operation under vacuum available
  • Variants for sterile operation available

Operating range

Shaft diameter:
d1 = 18 ... 100 mm (0.625" ... 4")
Pressure:
p1*) = 0.8 abs.... 25 bar (12 abs. ... 363 PSI)
Temperature:
t = -50 °C ... +220 °C (-58 °F ... +430 °F)
Sliding velocity: vg = 20 m/s (66 ft/s)
Axial movement: ±0.5 mm

* An integral stationary seat lock is not needed within the permissible low pressure range. For prolonged operation under vacuum it is necessary to arrange for quenching on the atmospheric side.

Materials

Seal face: Carbon graphite antimony impregnated (A),
Carbon graphite resin impregnated (B)
Seat G16: Silicon carbide (Q1)

Standards and approvals

  • EN 12756

Notes

Variant for sterile applications available. Please inquire.
