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 Packings produced using smaller or outdated braiding machines lack the strength of true cross-lock, are less dense and are not as square in cross-section.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.
Vulcan packings show a high degree of
resilience and consistency of volume. Their superior, lattice,
square inter-braid construction needs less gland pressure to seal,
resulting in reduced equipment wear, reduced gland maintenance and
increased packing life.

PAN FIBRE PACKINGS
Type VT2
Product Information
Vulcan VT2 is braided from pure Poly Acrylic Nitrile (P.A.N.) fibres which are the basis of the outstanding capabilities and performance of our PAN Fibre Packings.
Applications
Wide variety of process plant including pumps, valves, mixers, reactor vessels and reciprocating applications. Against general chemicals, solvents, oils, water and steam. A wide ranging packing, for use in arduous conditions in process applications, especially where alternative packings contaminate, cause excessive wear or require frequent maintenance and replacement. VT2 does not contaminate nor stain, making it particularly suitable for use in the food, water and paper industries.
