Type VR3
Braided packing, constructed from 100% Grafan yarns, to give truly exceptional capabilities and performance, pure Expanded Graphite Packing. Under compression in the gland, VR3 die-forms and can be merely cut to length and spiralled into the gland. There is no need for individual cut rings. Grafan is self-lubricating and will not shrink nor harden nor dry out in use.
Pressure rating: 200bar.
Rotary speed: 30m/s.
Temperature: -200°C +3000°C (Inert ATM),
-200°C +600°C (In Air).
pH range: 0 - 14.
Roll length: 8m.
Never use the product when maximum temperature and pressure are combined.
Gland Packing
We offer an extensive range of square section Gland Packing designed to minimise maintenance costs using the most advance materials. Available in other sizes and materials, please contact your local service centre for more details.
How to determine the correct Gland Packing size
• Measure diameter of shaft.
• Measure inside diameter of gland (or stuffing box).
• Gland ID - Shaft Diameter divide by 2
This figure gives you the cross section of the area to be packed.
• From the table, choose the gland packing with the closest size.
If your figure is in-between, use the next size up.
