Gland Packings
All Vulcan packings are square-braided on the most advanced specification braiding machines available. Twenty four and thirty six track braiders are utilised to produce four-ply, square inter-braid packings on all sizes from 3/8" (10mm) upwards. Fibres are run from the core of the packing section to the corner-posts and surfaces, whilst being cross-locked in a square, lattice construction, to produce maximum resilience and a highly dense, square packing.
The quality of a packing's braiding significantly affects the service life of the packing. Packings produced using smaller or outdated braiding machines lack the strength of true cross-lock, are less dense and are not as square in cross-section. The looser the braid of a packing, the lower its durability will be. Additionally, greater gland pressure is required to perform a seal, resulting in increased mechanical stress. As the packing deteriorates, frequent gland adjustments are required, causing more mechanical stress on the packing, leading to accelerated failure.

GLASS FIBRE PACKINGS
Type VG8L / VG8D
Product Information
Vulcan VG8L is interbraided from continuous filament, textured, air-blown glass yarns. The glass fibres are heavily lubricated and thoroughly impregnated with PTFE dispersion and an inert lubrication, both prior to and subsequent to braiding.
Applications
Type VG8L is a smooth, cool running packing for a wide variety of uses in a plant. Particularly useful on water and mildly abrasive slurries, solvents and chemicals in reciprocating and centrifugal pumps, mixers and valves.
Vulcan alternative Type VG8D is the self-same packing but the inert lubricants are replaced by an increased PTFE dispersion. VG8D is designed as a valve packing that is also suitable for a variety of static or slow moving applications up to 4 m/s.
