Walkersele® D7

Pressure resistant elastomeric radial lip seal.

  • Marine
  • Metallurgical
  • Rotary equipment

The D7 Walkersele is a key element of our well-proven family of radial lip seal products for rotating shafts and rotary plant.

Its robust design profile is suitable for applications where there is a pressure differential of up to 400 kPa / 4 bar (58 psi).

  • Operates at up to 400 kPa pressure differential when the sealing lip's heel feature is supported
  • Operates without the need for costly profiled lip support plates
  • Robust lip maintains sealing contact even on shafts suffering slight misalignment or eccentricity
  • Fabric-backed or glass-backed retained versions can be supplied in Walkersele OSJ-2 format for on-site joining to radically reduce seal change-out costs and downtime

  • Marine fin stabilisers
  • Marine propulsion azimuth swivel bearings
  • Marine rudder posts
  • Marine propulsion propeller shaft bearings
  • Metallurgical rolling mill chock bearings
  • Metallurgical crane gearboxes

  • Mineral and synthetic oils
  • Environmentally acceptable lubricants (EALs)
  • Water
  • Mineral and synthetic greases

  • Temperature: -30°C to +200°C (-22°F to +392°F) dependent on material choice
  • Pressure: pressure differential of up to 400 kPa / 4 bar (58 psi)
  • Surface speed: 20 m/s (3937 fpm) dependent on material choice
  • Please contact us for operating conditions outside these parameters
