Lionpak® 5302

A specialised graphite / carbon fibre packing for chemical and abrasion resistance.

  • Pumps
  • Valves

Lionpak 5302 is a specially developed packing that combines the advantages of soft expanded high purity 99% graphite yarn with the toughness of carbon fibre yarn at its four corners.

It is impregnated with James Walker’s proprietary, high temperature, graphite-based dispersion and an inorganic passive corrosion inhibitor.

  • Recommended for applications at high working temperatures with corrosive media
  • Good resistance to abrasion and wear
  • Excellent dry-running capabilities that reduce the need for continuous water flushing
  • Readily adapts to worn / pitted surfaces for smooth running under adverse mechanical conditions
  • Corrosion inhibitor safeguards metallic interfaces from galvanic corrosion

  • Pumps, valves, autoclaves, converters, mixers and reactors
  • Suitable for duties with steam, acids and alkalis, hydrocarbons, fuel and lubricating oils, FCC catalyst and bottom slurry, hydrogen sulphide, sulphur dioxide, thermic fluid, and abrasive media such as ash slurry, fly ash water and sea water
