James Walker Gland packing / fat cord for resilience and Chemical Resistance Lionpak 2302

Pure dry PTFE packing with low friction capabilities
Lionpak 2302 is an improved duplex braided packing of expanded PTFE with high quality graphite intimately entrapped in the porous structure of the PTFE resin. The product is further lubricated with molybdenum disulphide (MoS2).
Lionpak 2302 is designed for use in valves as well as in pump applications including centrifugal pumps and rotary equipment and reciprocating pumps and rams.

Prime features

• A dense packing offering a high degree of resilience and dimensional stability.
• The graphite provides heat dissipation to enhance the product’s long and efficient working life, which is also improved by the excellent thermal conductivity of molybdenum disulphide.
• Molybdenum disulphide enhances high speed rotary operations by minimising friction and wear.
• The molybdenum disulphide content also provides good chemical resistance.

Typical applications
Centrifugal and reciprocating pumps, valves, large diameter shafts, reactor vessels, agitators, mixers and autoclaves.
Suitable for duties with acids and alkalis of any concentration, phosphoric acid, hydrocarbons, solvents, raw water, demineralised water and condensateand cooling water.

Chemical properties
Compatible with media in the range pH 0-14, excluding strong oxidisers, molten alkali metals and fluorine compounds.
