Lionpak® 2504

PTFE / graphite / fluoropolymer packing for industrial water duties.

TYPICAL APPLICATIONS
  • Pumps
  • Valves

Lionpak 2504 is a specialised product which is a combination packing, duplex-braided packing. It comprises red fluoropolymer-based yarn and expanded PTFE intimately bonded with graphite yarn.

  • A dense packing with a high degree of resilience, incorporating a break-in lubricant
  • Both yarns are highly lubricated during manufacture; the red fluoropolymer-based yarn releases lubricant on inside diameter when packing is bent around the shaft
  • This lubrication system provides very smooth start-up for pumps, plus long service life with low friction properties to safeguard shafts and sleeves from wear
  • Graphite content aids heat dissipation to further extend the service life

  • Dynamic and static duties, including pumps, valves, mixers and reactors, across many industrial sectors. It is recommended for cooling water pumps and condensate extraction systems.
  • Also suitable for use with demineralised water, raw water, hydrocarbons, paints, synthetic resins, emulsions, viscous slurries, and many other general industrial media
