Vulcan VG8L is inter-braided from continuous filament, textured, airblown 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.

Vulcan VG8L can replace traditional packing in general, non-arduous duties, whilst being of superior square inter-braid construction. Consider that Type VG8Ls air-blown glass fibres are kinder to the shaft and you have a naturally square packing that will seal with less gland pressure, significantly reduce shaft wear and gland adjustment and thus increase packing life in light duties.

Type VG8LVG8D standard spool length is 8 metres. Custom lengths can be available - please contact us using the form.

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 VM1 is a universal Paper-Mill and Sugar-Mill packing, made of a unique Aramidic composite fibre. This special fibre combines an exceptionally high tensile strength 380, 000 psi (27, 000 kgcm), outstanding heat resistance, linked to low friction and excellent cool running properties. This is a strong Thermoset fibre packing but it is also extremely soft, assisted by our exclusive, three-stage, lubrication process. The low-friction factor reduces abrasion to up to 110 compared to Aramidic fibres, giving
high reliability and life, even in the most demanding of applications. VM1 is heat resistant and will not glaze, like usual Paper Mill & PTFE packing, even at high shaft speeds.

Type VM5 is a very similar product in more economical form. It will provide the same service but care must be taken not to over-tighten the gland nor starve the packing of product or flush lubrication.

Vulcan VP1 is 100% GORE fibre packing. This remarkable yarn is constructed from PTFE and Graphite intimately blended and locked and then treated with a high temperature, break-in lubricant. Vulcan VP1 is an outstanding packing for use in aggressive or arduous duties including the most difficult chemical environments. It is essentially chemically inert over the entire pH range. The unique combination of locked Graphite and PTFE creates a yarn with very high thermal conductivity, that does not harden, shrink, swell nor dry out and that is exceptionally smooth running with negligible shaft wear. User experience with G1 fibre has shown that, in practically all cases, greatly extended service life can be expected.

In order to obtain maximum benefit from this fibre, Vulcan VP1 is square inter-braided via a CROSS-LOCK process. The construction of VP1 increases the durability of the packing and reduces the gland pressure required to perform a seal. Periods between gland maintenance and packing replacement are thus even further extended and Type VP1s CROSS-LOCK braiding helps overcome extrusion problems, which can be the one negative of this fibre, particularly in lower quality braids.

Type VP1 standard spool length is 8 metres. Custom lengths can be available - please contact us using the form.

Applications : For use wherever the value of the best quality and material packing can be realised. Since the actual purchase cost of a packing is typically only 3% of the true utilisation cost, Vulcan recommend this PTFE GRAPHITE packing for all possible applications. They will increase service life whilst minimising wear and gland adjustments, against nearly all media in static, rotary and reciprocating uses.
