Diagonally braided from continuous Aramid fibres, impregnated with PTFE and high temperature silicone oil.
Properties
Extremely tough and durable packing with a chemical compatibility better than PTFE-lubricated asbestos and the unsurpassed mechanical strength of Aramid. The impregnation with PTFE and lubricant results in a low coefficient of friction and allows shaft speeds up to 15 m/sec. However, due to the toughness of Aramid we recommend a shaft (sleeve) hardness ≥ 60 HRC.
Application areas
Although mainly designed as a rotary pump packing, style 2004 is also suited for valves and piston pumps, mixers and reactors in the following industries: pulp and paper, pharmaceutical, food, sugar, chemical and petro-chemical, power stations, steel mills and many more. Also ideal
