Material composition: Multi -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.
Application : Designed for high pressure reciprocating pumps, medium speed centrifugals and valves. It can be used for general service steam, gases, solvents, mild acids, alkalis and most abrasive liquids. The packing will not stain in pulp & paper mill, pharmaceutical food and sugar industries.
Benefits: Long packing life in connection with abrasive media. Extremely pressure resistant in piston pumps. Suitable for a wide range of media.
