APPLICATIONS / USES :- A Special application performance packing made of combination of Pure PTFE fibre with additional polyamide
synthetic fibre reinforced in core & all four corners to provide sliding surface and heat dissipation property. The combining benefit of pure
PTFE, Polyamide & high temp resistance lubricants gland packing offers longer sealing ability due to excellent dimensional ability.
Application :
Sigma 225 Combination Packing is specially recommended for NH3 feed pump & valves, Oil & Solvents, caustics, Acids, Alkalies, Dyes, Chemicals Liquid ammonia
& carbonate solution under high pressure conditions, waste water treatment plants. Aggressive 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 :
Best gland packing for NH3 feed pumps.
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 aggressive media
High penetration & abrasion resistance of polyamide fibers ensure corner safety of packing
Available on demand: Square Section 6 mm sq upto 38 mm sq.sq.
