Features and Benefits

FEATURES and BENEFITS
Superior Sealing Performance
- Bellows Sealing System provides superior sealing performance throughout the wear life of the Rotary Union.
Designed For Dirty Media Applications
- Debris in contaminated media will not be captured in the Bellows Sealing System, which reduces clogging.
Maintenance Free
- The 9000G is maintenance free because there is no rolling element bearing, therefore no lubrication is required.
High Temperature Applications
- Offers the same design as the standard 9000 Series, but utilizes carbon graphite bearings for high temperature applications.
Ideal For High Temperatures
- The thrust collar allows for thermal expansion, making this an ideal union for high temperature, general purpose applications.
Flanged Mounted Units Available
- Consult Factory.
