Braided from shrink-proof synthetic fibre impregnated with PTFE dispersion containing graphite particles, silicon oil free, which is oxidized polyacrylonitrile fibre. Compared to traditional carbon fibre packing, it is not brittle, can suited for high peripheral speeds and food industries. Oxidized fibre has high strength and good thermal conductivity, PTFE and graphite makes the packing have excellent self-lubrication, so this packing does not damage shafts and has long life.
- Suitable for weak acids and alkalis, as well as media containing small amounts of solid particles
- Suitable for both dynamic and static sealing applications
- Used in centrifugal pumps, plunger pumps, mixers, and valves
- Handles hot water up to 160°C without cooling and up to 270°C with cooling
- Particularly well suited to hot water, condensate and main coolant pumps
