CONSTRUCTION
Style 2003 is an interlock braided packing, using pure PTFE yarn, reinforced with aramid corners. The yarns are pretreated with PTFE dispersion, plus a break-in lubricant to reduce the coefficient of friction, as well as the frictional heat created by high shaft speeds.
APPLICATION/SERVICE
Style 2003 packing, with its unique combination of PTFE and aramid fibers, is dimensionally stable, non-contaminating, has excellent lubricating and running characteristics, and becuase of the aramid corners, is very wear resistant. It handles acids, alkalis, and a broad range of chemicals. It is well sutied for service in rotary and reciprocating pumps, mixers, agitators and reactors, especially where abrasive wear is a problem.
