Artificial Fiber Braided White Gland Packing for Rotating Equipment
Artificial Fiber Braided White Gland Packing for Rotating Equipment is a group of 15 IMPA-coded items (codes 810472–810486) under Packings in the Packing & Jointing section (IMPA 81). All of them are priced per box.
Buying guide
Gland packing is braided rope pushed in rings into a stuffing box to seal a rotating or reciprocating shaft. This group holds white braided synthetic-fibre, non-asbestos packing for water and oil service on rotating equipment, boxed by square section from 5 mm upward.
It is used on centrifugal and reciprocating pumps that have no mechanical seal — sea-water, bilge, ballast and fire pumps. The engineer repacks a gland when leakage can no longer be adjusted out, and raises the packing by section size.
How to specify it
Size it from the stuffing box: cross-section = (box bore − shaft or sleeve diameter) ÷ 2. State that section in mm, the length or box quantity, and the service (fluid, temperature, pressure, shaft speed) so the supplier can confirm the grade.[1]
Order enough for a full set of rings plus spares. When repacking, joints are staggered 180° for a two-ring set, 120° for three and 90° for four or more, and the gland is first run with liberal leakage and tightened slowly.[1]
Rules and certificates
Packing must be asbestos-free: SOLAS regulation II-1/3-5 prohibits any installation of asbestos-containing material on all ships from 1 January 2011, and IMO lists joints and cords among items where asbestos is still found.[2]
Questions buyers ask
- How do I work out the packing size?
- Measure the stuffing-box bore and the shaft or sleeve, subtract and halve. That is the square section to order.
- Why does a newly packed gland need to leak?
- The leakage lubricates and cools the packing. Start with liberal leakage and tighten the gland nuts slowly and evenly to an acceptable rate.
