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

Custom solutions

While OEM seals suffice for some applications, many use cases require custom sealing solutions.

Whether you need a seal that meets specific performance requirements or can withstand extreme operating conditions, Ergoseal offers the in-house design and rigorous testing expertise to ensure your custom seal meets your precise specifications and performs in even the most demanding environments.
