Description
Pilotpack 5020 Packing is manufactured from a high strength, high modulus meta-aramid yarn. The yarn is produced by a special process that ensures that each single filament is covered by PTFE and a special lubricant. When braided using the ‘Crossplait’ technique of manufacture, this produces packing that gives excellent operating life over a wide range of applications, especially in abrasive media.
Laboratory tests have shown that Pilotpack 5020 packing has a polishing effect on the shaft where as other materials such as graphitised PTFE can produce surface grooves.

Pilotpack 5020 packing gives long life on rotating equipment and valves operating on slurries and abrasive media, typically in paper and pulp, sewage, cement, power generation industries as well the food and drink industry.
