Description
PILOTPACK 5035 packing is manufactured from a superior performance graphited PTFE yarn in the core and seams with high strength, high modulus meta-aramid yarn for the corners.
When braided using the ‘Crossplait’ technique of manufacture, this produces packing that has high thermal conductivity core and seams so giving low operating temperatures, combined with the meta-aramid corners that produce excellent extrusion resistance.
PILOTPACK 5035 has been specially developed using graphited PTFE with a high-temperature lubricant that is an integral component of the yarn. The meta-aramid yarn is produced by a special process that ensures every single filament is covered by PTFE and a special lubricant. Using these two yarns together gives excellent operating life over a wide range of applications, especially in abrasive media.
Applications
- Designed to operate on high-speed rotary and reciprocating applications.
- Excellent extrusion resistance even at high speeds and pressures.
- Minimal shaft wear combined with excellent abrasion and chemical resistance.
- High-temperature resistance combined with good dimensional stability.
- Suitable for many applications including chemical slurry pumps.
Water Regulations Approval Scheme
The material included in our packing is suitable for contact with wholesome water for domestic purposes having met the requirements of BS6920-1:2000 and/or 2014.
Chemical Compatibilities
For the pH range 1-14, the packing is chemically inert.
Sizes Available
All square sections are available from 3mm (1/8”) to 25mm (1”) are generally available from stock in differing lengths depending on the cross-section. Larger and rectangular sections can also be manufactured to order. PILOTPACK 5035 packings can also be supplied in preformed or die formed rings.
