APPLICATIONS / USES :- The packing made of high quality aramid fibers with PTFE-lmpregnation and lubricant additive.
Extremely hard wearing. It shows good chemical resistance, high elasticity and very low cold flow. Compare with other kinds of packing,
it can resist more severe media and higher pressure.
It is an universal packing, can be used for pumps in all types of industry such as chemical, petrochemical, pharmaceutical, food and sugar
industries, pump and paper mills, power stations etc. It is also a durable packing able to withstand granular and abrasive applocatons
Application :
Designed for serve on superheated steam, solvents, liquefied gases, sugar syrup and other abrasive fluids.
Sigma 216 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 :
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 other 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
Excellent in abrasive application. Well proven with aggresive media
