Lionpak® 2500

Tough, high performance packing with an elastomer core and WRAS approval for use with cold and hot potable water up to 85°C.

TYPICAL APPLICATIONS
  • Potable water
  • Pumps
  • Valves

Lionpak 2500 is a high performance packing that absorbs the eccentric action of worn shafts, spindles and bearings. It has a central core of temperature resistant elastomer.

This square sectioned packing is cross-plaited with tough aramid fibres at the corners to resist abrasion and wear. PTFE / graphite yarn at the centre of each side dissipates heat and presents a low friction face to the shaft or spindle.

A cost effective alternative without WRAS approval is also available, please download Lionpak 2503 datasheet for full details and specification.

  • Excellent abrasion resistance
  • Superior compression and recovery characteristics with out-of-true shafts and spindles
  • Excellent extrusion resistance
  • Low shaft wear
  • The high density elastomeric core provides resilience and resistance to high working pressures, and can absorb the vibration and eccentric movement created by worn running surfaces

  • Valves and pumps handling abrasive and aggressive slurries in pulp and paper mills, petrochemical plants, sewage works, metallurgical plants and china clay works
  • Also suitable for potable water and steam

Valve Stem Duties

  • Maximum operating temperature: +260°C (+500°F)
  • Minimum operating temperature: -50°C (-58°F)
  • Maximum system pressure: 25 MPa/250 bar (3626 psi)

Centrifugal Pumps and Rotary Equipment

  • Maximum operating temperature: +260°C (+500°F)
  • Minimum operating temperature: -50°C (-58°F)
  • Maximum system pressure: 2.5 MPa/25 bar (363 psi)
  • Maximum shaft speed: 20 m/s (3937 fpm)

Reciprocating Pumps and Rams

  • Maximum operating temperature: +260°C (+500°F)
  • Minimum operating temperature: -50°C (-58°F)
  • Maximum system pressure: 10 MPa/100 bar (1450 psi)
  • Maximum rod speed: 2 m/s (394 fpm)

Compatible with media in the range of pH 2-13, including water, steam, fuels, oils, solvents, waxes and mild acids and alkalis.

  • All popular square sections from 5 mm (3/16") to 25 mm (1") in boxes containing 8 m (26' 3") or in 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

WRAS approved for use with cold and hot potable water up to 85°C (185°F).
