PILOTPACK 5035 PACKING

• 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
• Approved by Water Research Council (WRAS ref no 0409511)

Description
Pilotpack 5035 Packing is manufactured from W L Gore GFO® yarn in the core and seams with a 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.

The GFO yarn has been specially developed using graphited PTFE with high temperature lubricant that is an integral component of the yarn. A special process that ensures that each single filament is covered by PTFE and a special lubricant produces the meta-aramid yarn.  

Using these two yarns together gives excellent operating life over a wide range of applications, especially in abrasive media.

Approvals
Approved by Water Research Council (WRAS reference number 0409511) for use on hot or cold potable water up to 85oC.
