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

seal-Type-110

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-100

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
