ExpaTen ETC

Perfect flange connection for high speed turbines

SCHAAF ExpaTen ETC offers the proven advantages of Expaten, but has been optimised for high-speed drives. The ExpaTen ETC is compactly built, fully encased and thus enables the reduction of turbulence of the entire connection.

Advantages

The SCHAAF ExpaTen ETC offers you many advantages compared to conventional fixing devices and methods of mounting:

  • Simple and quick installation and removal of ExpaTen ETC even after years of use – nearly unlimited times
  • High torque transmission, completely free from backlash
  • 100% positive locking and frictional connection all the time after mounting, no slipping between the flanges
  • Special surface treatment for minimising micro movement and decreased dynamic axial forces
  • Specially designed for connections with high speed drives
  • Torsionally and flexurally rigid connection even with shock-like changes in speed, torque or direction of rotation or load.
  • No overlapping screws or nuts – no windage – higher turbine efficiency
  • The smooth protection caps reducing noise, vibration and increasing efficiency
  • Requires only one hydraulic pressure source for installations or removals
