carbonized fiber packing/square packing seal/stuffing box packing material

Specifications Braided from shrink-proof synthetic fiber impregnated with PTFE, silicon-oil-free, which is oxidized polyacrylonitrile fiber.

Carbonized Fiber Packing:  Compared to traditional carbon fiber packing, it is not brittle, can suited for high peripheral speeds and food industries. Oxidized fiber has high strength and good thermal conductivity, PTFE makes the packing have excellent self-lubrication, so this packing does not damage shafts and has long life.   APPLICATION:  It can be used in weak acids and alkalis or media containing few grains of solid particles, both dynamic and static, mainly used for centrifugal pumps, plunger pumps, mixers and valves.Without cooling it can be used with hot water up to 160°C , with cooling it can be used with hot water up to 207°C. Particularly ideal for hot water, condensate and main coolant pumps.   PARAMETER:
