TYPE
DESCRIPTION
9010
GRAPHITE FILAMENT PACKINGService: Severe service packing. Handles strong acids and alkali solution except fuming nitric acid, oleum and fluorine. Handles high temperatures and extremely high shaft speeds.

Construction: Light weight graphite/carbon fibers, twisted together and interlock braided. Contains a special lubricant to provide a bearing film and prevent wicking.

Service Limits: pH range: 0-14
Temperature: 1200°F (in steam): 850°F (in presence of oxygen)—–Shaft speed: 4000 FPM

9011
BRAIDED FLEXIBLE GRAPHITE PACKINGService: A multi-service packing capable of a wide variety of uses throughout a plant. It may be used in valves, pumps, expansion joints, mixers and agitators in the hostile environments of hydrocarbon processing, pupl and paper, power generation, metal-working and other industries where effective sealing is vital.

Construction: A packing manufactured from flexible graphite in a unique braid construction. It is not wire-reinforced thus minimizing shaft and stem wear. It is also free of any fiber carrier.

Service Limits: pH range: 0-14
Temperature: 480°C (oxidizing atmospheres) 3000°C (Inert or reducing atmospheres)

Shaft speed: 3000 FPM
Pressure: 4000 psi

9020
CARBON FIBER W/ GRAPHITE COATINGService: Handles water, steam, boiler feed and aqueous solution of acids and alkalies. Seats quickly; breaks in without extensive adjustments. Use for high speed pumps, blowers, driers, high temperature valves and furnace gasketing.

Construction: Carbon fiber interlock braided, impregnated with proprietary lubricants and graphite particles which fill voids, act as a break-in lubricant, and block leakage.

Service Limits: pH range: 0-14
Temperature: 1200°F (in steam): 650°F (in presence of oxygen)
—–Shaft speed: 3000 FPM

9030
VALVE STEM PACKINGService: A firm, high density valve stem packing. Recommended for use in super-heated steam, most chemicals, mild acids and alkalies. Excellent choice as end rings in flexible graphite ring sets.

Construction: Special high temperature, high strength, rugged-duty yarn plus Inconel® wire reinforcement. Impregnated with special high temperature resistant compound and coated with fine particles of Graphite and Molydisulfide to act as surface lubricant. Also treated with a sacrificial material to alleviate electrolytic action.

Service Limits: pH range: 2-12—–Temperature: 1200°F (650°C)—–Pressure: 2250 psi

9040
G.FO.® PACKING
(Registered Trademark of W.L. Gore Co.)Service: For use in pumps, valves, reciprocating and rotating shafts, mixers and agitators. Especially designed for services involving surface speeds and temperatures higher than those normally specified for packing manufactured from pure PTFE filaments. Can be safely used in all chemical pump applications with the exception of molten alkali metals, fluoride, oleum, fuming nitric acid, aqua regia and other strong oxidizing agents. It is also suitable against water, steam, petroleum derivatives, vegetable oils and solvents.Construction: Interlock braid of expanded PTFE filament in which fine particles of pure graphite have been encapsulated throughout.Service Limits: pH range: 0-14—–Temperature: 540°F (280°C)—–Shaft speed: 4000 FPM
9041 PTFE / GRAPHITE FILAMENT WITH ARAMID CORNERSService: Offers the strength of aramid fibers and the heat disspating, low friction qualities of expanded PTFE/Graphite. Use in paper mill stock pumps, agitators and other areas where strength and good lubricating qualities are required.

Construction: Interlock braid of expanded PTFE/Graphite with aramid yarn on the corners, the aramid corners prevent extrusion.

Service Limits: pH range: 3-11—–Temperature: 500°F (260°C)—–Shaft speed: 2250 FPM
