Bellows
The bellows design overcomes many of the problems associated with pusher designs. The absence of a dynamic gasket eliminates the possibility of “hand-up”, caused by build-up of deposits or gasket swell.

Features & Benefits
- 0.20 mm (0.008 inch) thick standard welded bellows provides maximum resistance to corrosion, shaft vibrations, and centrifugal forces
- Rotating bellows acts to clear convolutions and prevent accumulation of debris.
- Absence of springs and dynamic elastomers reduces clogging vulnerabilities.
- Circulating device integrated into the dual seal cartridge circulates barrier fluid to keep the seal faces cool. A circulating device is also available on single seals for fluids over 75°c (167°F)
- Available multi-port flush distributes flush fluid evenly around the seal faces for uniform cooling.
- Part interchangeability between single and dual seal arrangements minimizes inventory requirements and maximizes design flexibility.
