Pure PTFE Yarn Packing With PTFE Dispersion is manufactured from Pure PTFE Fibre in interlock braid with pre lubed sealing agent. It has excellent heat dissipating property and is inert to virtually all chemical media. It is a soft resilient packing with high dimensional strength & low coefficient of friction. Further, dispersion of PTFE aids in handling high pressures.

Applications: Suitable for all kind of pumps, valves, agitators, mixers, dryers, washers, refiners etc. which handles acids & alkali, Dyes and Corrosive Chemicals, Bleach, Chlorine, Paints, Foodstuffs, water, Condensate, Oils, Solvents, Caustics etc.


Technical Parameters:

Product Description: Expanded Pure Graphite interlocked braided gland packing incorporating sacrificial metal corrosion inhibitor to protect the shaft from galvanic corrosion and self generating lubrication that accommodates & aids self-adjustment on tightening. It has excellent chemical resistant capability and is highly anti-frictional, hence no fear of scoring of sleeves/plungers etc.

Service Media & Applications: Suitable for pumps and low pressure valves handling Acids, Alkalies, Solvents, Thermic Fluid, Petrochemical, Boiler Feed Water, Condensate etc.


Technical Parameters:

The packing is interlocked braided from Pure Aramid Fiber with an impregnation of break-in lubricant & incorporating special Fluoropolymer based dispersion for high degree of resiliency. This packing has very high strength & tenacity with an exceptional resistance to abrasive media. It is safe to be used in food & pharmaceutical industry.

Service Media & Applications: Extremely suitable for pumps and agitators handling sludge & sewerage in Water Treatment and ETP plants. Used for harsh media such as Molten Synthetics, epoxy resins, viscous fluids, fruit pulp, high abrasive Bleach or Wood pulp, Concrete, Ash Slurry, Mud Slurry, Fly Ash water, chemical slurries etc.
