Metal Bellows Seal
A sealing system must function at peak performance even when conditions are most demanding – high pressures or temperatures, extremely thick or chemically corrosive products, high-frequency vibrations, etc. Since metal bellows seals don't have a semi-dynamic sliding elastomer (like a conventional mechanical seal), there's no potential for seal hang-up or shaft/sleeve fretting. They're an ideal solution for such applications.

Seal Types

Type 100
Ideal for process pumps and compressors unsuited for elastomers, our Type 100 seals have a self-cleaning effect.
FEATURES
- Rotating bellows
- Metal bellows acts as both a spring and hermetic secondary seal
- Can be constructed from any weldable material
- Can be designed to be compatible wtih nearly any media
- For unstepped shafts
- Balanced
- Independent of direction of rotation
PARAMETERS
- Pressure: 375 psi [25 bar] max
- Temperature: -40 to 800 °F [-40 to 425 °C]
- Speed: 5000 fpm [25 m/s] max
- Typical Applications: gearboxes, fixed and rotary wing aircraft, process pumps, compressors, and other rotating equipment.

Type 110
For high-speed rotation, our Type 100 seals feature a stationary metal bellows and are ideal for applications where elastomers are undesired.
FEATURES
- Stationary bellows
- Metal bellows acts as both a spring and hermetic secondary seal
- Can be constructed from any weldable material
- Can be designed to be compatible with nearly any media
- For unstepped shafts
- Balanced
- Independent of direction of rotation
PARAMETERS
- Pressure: 375 psi [25 bar] max
- Temperature: -40 to 800°F [-40 to 425 °C]
- Speed: 5000 fpm [25 m/s] and beyond - max speed determined by application pressure-velocity (PV)
- Typical Applications: gearboxes, fixed and rotary wing aircraft, process pumps, compressors, and other rotating equipment
