Description
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 as anti-extrusion rings in combination
with softer packings.
Application media
The chemical resistance of Aramid together with the PTFEimpregnation allows this packing to be used in connection with
most chemicals (except very corrosive ones), water, steam, oils,
solvents, etc., while its extrem abrasion resistance makes it ideal
for use with abrasive sand, slurry and other gritty media.
Not suitable for
Highly concentrated acids, caustic solutions, alkali metals,
oxygen.
Benefits
Extremely durable and abrasion resistant packing suitable for a
wide variety of media in many different industries.
