 Braided from high quality aramide fibres with PTFE-Impregnation and lubricant additive. Extremely hard wearing. 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. ASSEALS 2200L Aramid fiber packing with an inert lubricant
An extremely durable, highly abrasive resistant packing, It is ideal for slurry service application.
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 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 uncooled up to 160¡ãC.
It can be used as stand-alone packing also combined with others as anti-extrusion ring.

2220 White PTFE Packing with Aramid Corners
Muti-yarn packing, the corners of packing are made of aramid yarns impregnated with PTFE, while the friction faces are made of pure PTFE yarns. This structure enhances the lubrication ability of aramid fiber and improves the strength of the pure PTFE.
2222 White PTFE & Aramid in Zebra Braided Packing
Muti-yarn in zebra braided packing consisting of pure PTFE and araimid.
2230 Graphited PTFE Packing with Aramid Corners
Interlock braid of graphited PTFE with aramid yarn on the corners. This improve resistance in higher pressure applications. It has excellent sliding velocity and thermal conductivity compared to 2220
2232 Graphited PTFE & Aramid in Zebra Braided Packing
