Description
A high performance packing that absorbs the eccentric action of worn shafts, spindels and bearings. It has a central core of temperature resistant elastomer. The 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.
Typical applications
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, foodstuffs and steam.
