LabTecta66 ST-STAX

Bearing Protection – Steam Turbine Applications

Process steam turbines present a unique challenge for bearing protection. As the carbon rings containing the steam wear, high temperature / high velocity steam travels down the shaft directly at the bearing seal.

Standard OEM labyrinth seals have proven to be ineffective preventing steam ingress. AESSEAL® has developed LabTecta® designs specifically designed for steam turbine applications.

Features:

  • High temperature static shaft seal

  • Steam deflector / Flinger

  • Aflas® ‘O’ rings as standard

  • Internal shut-off valve

  • Extra clearances for thermal expansion

For smaller steam turbines, the LabTecta®ST design provides excellent protection in a compact package. For larger steam turbines, the LabTecta®ST-STAX provides easy installation with the capability to accommodate large axial shaft movement.

Standard designs are available for common steam turbines models like the Elliott® YR series. Specific designs can be manufactured at no additional charge.
