Lionpak® 5304

A specialised carbon fibre packing for chemical resistance and low friction.

  • Pumps
  • Valves

Lionpak 5304 is a high grade packing of interlock-braided carbon fibre coated in PTFE.

The packing is thoroughly impregnated with James Walker’s proprietary suspension to enhance sealability. This suspension is based on graphite, high temperature lubricant and corrosion inhibitors.

  • Tough carbon fibre construction capable of handling steam, as well as the highly corrosive chemicals and abrasive media used in metallurgical processing plant
  • Entrapping the suspension in a braided carbon fibre matrix increases lubrication as well as acting as a blocking agent
  • Corrosion inhibitor safeguards metallic interfaces from galvanic corrosion

  • Pumps, valves, reactors, agitators, mixers and other static or dynamic equipment in metallurgical processing and general industry
  • Suitable for duties with steam and hot water, caustic chemicals (such as sodium hydroxide, potassium nitride, etc), acids and alkalis, organic chemicals, dry powder and thermic fluids

Valve Stem Duties

  • Maximum operating temperature: +260°C (+500°F)
  • Minimum operating temperature: -100°C (-148°F)
  • Maximum system pressure: 20 MPa/200 bar (2900 psi)

Centrifugal Pumps and Rotary Equipment

  • Maximum operating temperature: +260°C (+500°F)
  • Minimum operating temperature: -100°C (-148°F)
  • Maximum system pressure: 2 MPa/20 bar (290 psi)
  • Maximum shaft speed: 20 m/s (3937 fpm)

Reciprocating Pumps and Rams

  • Maximum operating temperature: +260°C (+500°F)
  • Minimum operating temperature: -100°C (-148°F)
  • Maximum system pressure: 15 MPa/150 bar (2175 psi)
  • Maximum rod speed: 2 m/s (394 fpm)

Lionpak 5304 may be suitable for higher pressures on certain reciprocating duties, please contact us for details.

Compatible with media in the range pH 0-14, excluding strong oxidising agents.

  • All popular square sections from 3 mm (1/8") to 50 mm (2") in boxes containing 8 m (26' 3") in coil form or on spools as detailed in the product datasheet
  • Also supplied as split preformed rings and sets
  • Please refer to the product datasheet for spool ordering information
