PUMP PACKING 

A continuous filament PTFE fiber.  Style 5889 is a dimensionally stable yet relatively soft and flexible packing.  Treated with PTFE dispersion and an inert ingredient, it's an excellent choice for high speed rotary shaft service in marine, waste/water treatment, and most volatile applications.  Pre-shrunk to avoid packing wear and shaft scoring, Style 5889 is also very non-porous.  It's often found in sump pumps, chlorinators, alkaline softeners, slip-type expansion joints, strong acid situations, coke plant hot oil pumps, reciprocating rods, rams and plungers.
