AIGI 24 High-Temperature Pump Packing
AIGI 24 is a pump packing braided from a heat-resistant, high-carbon-content fibre and dipped in special lubricants. The lubricants allow faster pump start-up and better sealability, while the fibre's extreme heat dissipation and low friction mean the packing will not burn. It is purpose-built for high-temperature, high-speed pump service.
Product Benefits
- Survives dry start-up: Start-up is when packings suffer most: faces run dry and heat builds before the process fluid takes over.
- Dipped lubricants: AIGI 24's dipped lubricants carry it through start-up faster and seal better from the first turn of the shaft.
- Will not burn: Unlike traditional carbon-fibre packings, AIGI 24 will not burn, thanks to its extreme heat dissipation and low-friction properties.
- Very wide pH tolerance: Covering strongly acidic through strongly alkaline media, it handles duties that scorch or dissolve lesser packings.
Where It's Used
- Hot, fast pumps: AIGI 24 is designed for high-temperature and high-speed pumps.
- Wide equipment range: It also serves agitators, mixers, condensate pumps, boiler feed pumps and vacuum pumps.
- Core industries: Power, metals processing and pulp and paper are its core industries.
- Pulp and paper machines: In mills it suits refiners, stock pumps and pulpers: hot, fast, hard-working machines where packing failures are costly.
Good to Know
- Steam versus oxygen: The black carbon-fibre braid tolerates extremely high temperatures in steam service; in oxygen service the allowable temperature is considerably lower, so state the medium when selecting.
- High pressure and speed: Pressure and shaft-speed capability are both high for a braided packing.
- Through-body lubrication: The special lubricants are applied by dipping rather than surface coating, so the lubrication is carried through the packing body.
- Installation matters: As always with high-duty packings, correct ring sizing and gland practice determine how much of that capability is realised in service.
