Carbon-filled PTFE Packing for ANSI Pumps
A great general purpose packing for ANSI pumps is carbon-filled PTFE. Finely ground particles of the highest quality of graphite are in a PTFE matrix that controls graphite migration. This packing does not tend to glaze. In addition, the carbon allows heat to migrate away from the shaft and sleeve rather than insulate the heat.
This packing can handle shaft speeds to 4400 feet per minute (FPM), temperatures to 550 degrees F (287 degrees C) and a pH range of 0-14. It is black in color.
