Lionpak® 2501

PTFE / aramid packing for abrasion resistance with low friction for pumps and valves.

  • Pumps
  • Valves

Lionpak 2501 is a dense braided combination packing, with tough aramid yarn at the corners, PTFE yarn at the faces, and a strong core of extruded and expanded PTFE cord.

The aramid yarn is impregnated with an anti-friction fluoropolymer dispersion and a break-in lubricant, while the PTFE faces are treated with a high temperature resistant and inert lubricant.

  • Dense construction that offers excellent sealability
  • Aramid corners enhance long life in harsh plunger pump applications
  • Expanded PTFE core provides improved compressibility and responsiveness, compared to the aramid core typically used on similar products
  • PTFE faces provide low friction and low-wear running on shafts

Centrifugal, reciprocating and plunger pumps (particularly dosing pumps), valves, reactors, autoclaves and agitators. It can also be used as a replacement for traditional lip seals in certain applications. Suitable for use with ammonia, urea and carbamate condensate in fertiliser plant, pigments, dyestuffs, paints, amide, detergents, hydrazine, trisodium phosphate, sodium hexametaphosphate and slurries.
