AIGI 98 High-Temperature/High-Speed Pump & Valve Packing
AIGI 98 is an interbraid packing made from high-quality carbon-fibre-reinforced flexible graphite tape. Its extreme temperature resistance, self-lubricating nature and high heat dissipation make it a natural fit for the hottest, fastest pumps and valves in heavy process industry.
Product Benefits
- Self-lubricating, cool-running: Flexible graphite is inherently self-lubricating and conducts heat away from the shaft, so 98 runs cool even on high-speed equipment where friction would destroy conventional packing.
- Carbon-fibre strength: The carbon-fibre reinforcement adds the tensile strength that pure graphite lacks, giving the braid both tremendous sealability and mechanical durability.
- Full pH coverage: One packing covers services from strongly acidic to strongly alkaline across essentially the full pH spectrum.
- Consolidates specialist products: At extremely high temperatures and shaft speeds it genuinely replaces what would otherwise be several specialist products.
Where It's Used
- Hot, fast pumps and valves: AIGI 98 is specified for high-temperature, high-speed pumps and for valves.
- Home industries: Power plants, chemical and petrochemical plants and refineries are its core territory.
- Routine severe services: Hot hydrocarbon, steam and aggressive chemical services are everyday duties in those industries.
Good to Know
- Dense, resilient braid: This is a black, graphite-based packing; the reinforced flexible-graphite tape gives it a dense, resilient braid that conforms well to worn stuffing boxes.
- Valve-stem capable: It tolerates very high reciprocating pressures, which is why it doubles as a valve-stem packing.
- Light gland load: Graphite packings need only light gland load to seal; over-tightening wastes their self-lubricating advantage.
- Check shaft compatibility: Where electrochemical compatibility with the shaft material matters, confirm the pairing as you would with any carbon or graphite product.
