PTFE with Graphite Packing
Constructed from a high-standard ePTFE-encapsulated graphite with silicon lubricant.
Description
PTFE with graphite packing is made from PTFE graphited yarn and a high-temperature break-in lubricant. It is an excellent, general-service packing, exhibiting good thermal conductivity characteristics, resulting in a higher shaft speed than other packing. This packing combines high chemical resistance with thermal conductivity to run cooler at higher speeds.
Advantages
This style is an excellent general-service and corrosive-service packing with many benefits.
- Good chemical resistance may withstand a wide range of rotary applications
- Chemical resistance combined with thermal conductivity operates cooler
- Low Friction & Wear
- Easy to install
Applications
PTFE with graphite packing resists most caustic media; it is commonly used in centrifugal and rotary food processing equipment. It is also suitable for blenders, mixers, cookers, dryers and pumps.
Media Use
- Aromatic and aliphatic solvents
- Petroleum and synthetic oils
- Aqueous solution
- Alcohol and ester
- Light-mild slurry
- Steam
- Acids
- Alkalis
