PTFE-Graphite + Polyamide Fibre Gland Packing(CombinationPacking)
ITEM : Sigma 234

PRODUCT NAME : PTFE-Graphite + Polyamide Fibre Gland Packing(CombinationPacking)



APPLICATIONS / USES : A Special application performance packing made of PTFE Graphite filament ( The PTFE resin is combined with graphite & expanded by using the latest technologies resulting in high quality filament) with additional yellow polyamide synthetic fibre reinforced in core & corners to provide sliding surface and heat dissipation property. The combining benefit of PTFE-Graphite, Polyamide & high temp resistance lubricants gland packing offers longer sealing ability due to excellent dimensional ability.
Product Description :
Sigma 234 Combination Packing is recommended for Oil & Solvents, caustics, Acids, Alkalies, Dyes, Chemicals
Liquid ammonia & carbonate solution under high pressure conditions, waste water treatment plants. Agressive organic / inorganic Chemical Rotary and reciprocating plant pumps & valves, oils, corrosive gases, Dyestuffs, synthetic resins,White and black liquor, wood pulp, detergent, hydrocarbons, steam valves, metering pumps, reactors, mixers, autoclave glands, bauxite slurries, bottom ash slurry pumps, mineral handling slurries, tailings pumps and other slurry processing applications.
Prime Features :
Pressure  Psi bar to 300 psi (20 bar) rotary/ centrifugal;  to 2000 psi (138 bar) valves
Shaft speed M/s to 3000 rpm
Density g/cm3 1.4
Temperature °C -328 0F (-2000C) to + 5720F(+3000C)
PH range 0 -14
Long maintenance free service life.  Minimal shaft wear and leakage
Pliable, wear-resistant and dimensionally stable. Rugged and non-toxic
Extended service life by up to 400% in harsh environments.
Six times better heat conduction as against pure PTFE packings at comparatively high speeds.
Significantly low thermal expansion thus resisting ‘ over expansion’ extrusion under service.
Suitable to centrifugal & reciprocating pumps even at high pressure
PTFE Graphite fibre at faces enhance low friction  for shaft / sleeve safety
Excellent in abrasive application. Well proven with aggresive media
High penetration & abrasion resistance of polyamide fibers ensure corner safety of packing
