TYPE
DESCRIPTION
9050
PTFE FILAMENT W/ LUBRICANTService: A pliable and soft, yet dimensionally stable packing, which has excellent lubricant and running characteristics. It is suited for high speed rotary shaft service and handles all acids, alkalies and most chemicals with the exception of molten alkali metals.

Construction: Interlock braid, using purePTFE filament pretreated with PTFE despersion plus a break-in lubricant to resuce the friction coefficient as well as the fricitonal heat created under high shaft speeds.

Service Limits: pH range: 0-14—-Temperature: 500°F (260°C)—–Shaft speed: 2250 FPM

9051
PTFE WITH ARAMID CORNERSService: Designed for high pressure reciprocating pumps, mudium speed centrifugal shafts and valve stems. Especially formulated for severe service involving high pressure applications.

Construction: Interlock braid construction, interweaving atamid fibers on the corners and pure PTFE filaments in the body, to prevent extrusion and to improve resistance in higher pressure applications.

Service Limits: pH range: 3-11—–Temperature: 500°F (260°C)—-Shaft speed: 1970 FPM

9055
LUBRICATED PTFE FILAMENT, FDA APPROVEDService: For use in food and drinking water processing and handling equipment. All materials of construction are FDA approved.

Construction: Interlock braid of pure PTFE filament pretreated with an FDA approved lubricant.

Service Limits: pH range: 0-14—-Temperature: 500°F (260°C)—–Shaft speed: 2250 FPM

9056
PTFE FILAMENT, DRYService: A firm, high density PTFE filament commonly used in valves oar lower shaft speed applications. Recommended environments are all types of chemicals, aggressive fluids, gases and solvents, with exception of molten alkali metals. It is especially suited for oxygen or other services where no organic materials or lubricants other than PTFE are allowed.

Construction: Interlock braid using pure PTFE filament pretreated with PTFE dispersion.

Service Limits: pH range: 0-14—-Temperature: 500°F (260°C)—–Shaft speed: 600 FPM

9060
ARAMID FILAMENT PACKING W/ PTFEService: Able to withstand granular and abrasive applications. It is resommended for service in steam, slurries, petroleum derivatives, solvents, chemicals and liquified gases.

Construction: Interlock braid, using aramid filaments treated individually with PTFE suspensoid. The packing is also lubricated with a silicon-based compound for quick and easy break-in.

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