Type 1118 Metal Bellow Mechanical Seals

For high-temperature applications and demanding operating conditions. These seals are ideal for equipment with high start-up torque, thanks to a bellows unit design that operates independently of torque transmission.

To ensure outstanding thermal performance, Grafoil is used as the secondary sealing element, delivering reliable sealing in temperatures up to 400°C. The precision shrunk-fit seal face design effectively minimizes face distortion, helping to reduce leakage and wear rates to exceptionally low levels across a wide range of pressures and speeds.

With their robust construction and advanced materials, Type 1118 seals offer long-lasting, reliable sealing solutions for high-temperature industrial applications.
