Pure Aramid Fiber Packing
Aramid fiber packing is braided from high quality Aramid/Kevlar fiber with lubricant additive. Extremely hard wearing.
Aramid packings are their high strength and low weight. Like graphite, the aramid packings have slightly negative thermal expansion axial coefficient which means that the dimensions of aramid packings can be made thermally stable.

Key Features
It shows good chemical resistance, high elasticity and very low cold flow. It is wear resistant but may damage the shaft if not used properly. A minimum shaft hardness of 60HRC is therefore recommended.
Compared with other kinds of packing, it can resist more severe media and higher pressure.
The packing is also lubricated with a silicone-based compound for quick and easy break-in.
Application of Pure Aramid Fiber Packing
It is a universal packing which can be used for pumps in all types of industry such as chemical, petrochemical, pharmaceutical, food and sugar industries, pulp and paper mills, power stations etc. It is also a durable packing able to withstand granular and abrasive applications, it is recommended for serve in superheated steam, solvents, liquefied gases, sugar syrups and other abrasive fluids.
For hot water applications it can be used un-cooled up to 160 Deg.C
It can be used as stand-alone packing also combined with others as anti-extrusion ring.
