PTFE Graphite Packing

Dual-action rotary pump braid

PTFE / graphite blended packing that combines low friction with heat dissipation for high-speed rotary pump shafts.

PTFE chemical resistance plus graphite heat dissipation
Runs cool at high rotary shaft speeds
Low friction reduces power draw and shaft wear
Resists glazing and hardening in service
Versatile across clean and mildly aggressive media

Temperature: -200°C to +280°C
Pressure: Up to 100 bar (valve) · 20 bar (rotary pump)
pH range: 0 – 14

In ServiceUSE

Where it holds the line

PTFE-graphite packing brings together the best of both worlds for rotary pumps: the low friction and chemical resistance of PTFE with the thermal conductivity of graphite that carries frictional heat away from the shaft. Each filament is impregnated so the braid runs cool at speed, resists glazing and protects the shaft sleeve from scoring. It is the all-rounder for general process pumps where a single packing has to handle a wide range of clean and mildly aggressive media at higher surface speeds.

Typical applications

01General-service rotary process pumps
02Hot-water and condensate pumps
03Centrifugal pumps at higher speed
04Mixers and agitators
05Mildly aggressive chemical service
