L4 / L5 seals belong to the family of rotating multi spring balanced seals.

Salient features:

  • These seals are available for high pressure.
  • Ideally suited for clear liquids & mild slurries.
  • Used in industrial process pumps, chemical, petrochemical, fertilizer and pharma plants.
  • Seal faces are designed and optimized using CAE for minimum heat generation and thus can be used for low Viscosity fluids.
  • Can be installed in narrow stuffing boxes in pumps as per ISO 3069.
  • Drive to the seal ring is through a special clutch type arrangement, which enables the seal to take heavy torques.
  • Springs are housed in the drive collar and are exposed to the process media thus getting automatically cleaned by centrifugal forces.
