VM1 / VM5
VM1 / VM5
Vulcan Seals Type VM1 Gland Packing is a universal Paper-Mill and Sugar-Mill Gland Packing, made of a unique Aramidic composite fibre. This special fibre combines an exceptionally high tensile strength 380,000 psi (27,000 kg/cm²), outstanding heat resistance, linked to low friction and excellent cool running properties. This is a strong Thermoset fibre Gland Packing but it is also extremely soft, assisted by our exclusive, three-stage, lubrication process.
The low-friction factor reduces abrasion to up to 1/10 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.
Type VM1/VM5 standard spool length is 8 metres. Custom lengths can be available - please contact us using the form.
