High Resilience Kevlar Gland packing Low Cold Flow Chemical
resistance
Descriptions:
Kevlar packing is braided from Kevlar which is dipped in emulsion
and treated with lubricant.Normally used at dynamic sealing and
static sealing location for particle crystal medium.the Kevlar
fiber features super high strength and perfect wear and tear
resistance. Normally used as stop ring at medium end (where a lot
particle crystal are existed)and used together with other kind of
packing.
Kevlar Packings is a high quality aramid fiber impregnated PTFE and
lubricant additive. Good chemical resistance, high elasticity, low
cold flow. Nature has excellent high speed, high modulus (called
artificial metal line)
The high quality DU PONT Aramid Fiber dips PTFE emulsion and
lubricating additives. The most outstanding performance is high
strength, meanwhile a relatively good chemical resistance,higt
resilience,low cold flow. Althoug it is quite wearing resistant,
used improperly, it will wear out the pump shaft, so we recommend
the surface hardness pf the pump shaft and the protection sleeve
reaching 60HRC. This packing is inner dipped the mixture mainly
silicone oil, it si easy to assemby-disassembly fast and
conveniently. It is a universal type packing, which is widely used
in various industry areas, chemical, refinery, medical, food, sugar
making, paper making and electric power,etc. This packing is
durable, suitable for wear medium containing solid particles,
recommended using for overheat steam, solvent, alcohol vapor, syrup
and other wear fluid. It can be used for 160°C hot water under
coolant-free circumstance. It can be singly used, or combine with
other packing, put in the two ends, as an extrusion-proof ring.

Applications
Widely used in various industrial fields, such as chemical
industry, oil refining, pharmaceutical, food, sugar, paper and
power industries; pump, valve and mixer is often used for rotating
equipment.
Although mainly designed as a rotary pump packing, Kevlar packing
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 packing.
