PTFE packing is a good sealing material, and it is made by braiding PTFE strips.
With High cross-sectional density and structural strength ;
Low coefficient of friction result in easy shaft running ;
Long lubricant squeezed out under operating pressure.
Application:
PTFE packing is for dynamic seal at high linear speed, often used in check and needle valve stems, reciprocating rods, rams, and plungers, and safety injection system valves.
Specifications:
-Pressure: 2MPa in centrifugal pumps, 10MPa in piston pumps, 20MPa in valves
-Temperature: <280°C
-Linear speed: 4m/s in centrifugal pumps, 2m/s in piston pumps, 2m/s in valves
-pH range: 0 - 14
-Thickness: 3.0 - 50mm
Pure Graphite Ptfe Packing are found in electric engines, transmissions, agricultural machines, bearing pedestals and rolling mills.
Pure Graphite Ptfe Packing used to seal against dust, dirt, lubricant, oil or water spray from the outside.
