APG’s Style 1179 pump packing features carbon filament fibers made from a PAN base, with a minimum carbon content of 95%. Staple fibers from PAN produce a more flexible packing than filament fibers, which tends to fracture when bent. Each individual strand is coated with pure PTFE and cured before braiding which prevents color contamination and carbon migration. During the braiding process, pure PTFE is applied throughout the body of the packing. The packing is lubricated under hydraulic pressure with a proprietary nonpetroleum lubricant, containing no sulfur, silicone, or waxes. Style 1179 is recommended for operating temperatures up to 600°F / 345°C and shaft speeds up to 3000 feet per minute for most chemical services, except strong oxidizers, in pulp mill equipment, steaming vessels, top separators, refiners, outlet devices, blow pumps, stock pumps, agitators and valves.
