Vulcan Mechanical Gland Packing

1 of 1

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 Packings produced using smaller or outdated braiding machines lack the strength of true cross-lock, are less dense and are not as square in cross-section.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.
