Aramid Fibre Packing with PTFE
Braided from high quality aramid fibre with PTFE impregnation and lubricant additive. Extremely hard wearing. It shows good chemical resistance, high elasticity and very low cold flow. It is wear resistance 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 high pressure. The packing is also lubricated with a silicone-based compound for quick and easy break-in.
APPLICATION:
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 station etc. It is also a durable packing able to withstand granular and abrasive applications, it is re-commended 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°C. It can used as stand-alone packing also combined with others as anti-extrusion ring.
