FLUDEX Fluid Coupling

  • Hydrodynamic fluid coupling
  • Nominal torque: 1.2 kW – 2,500 kW
  • Operating temperatures: -40 °C to +50 °C
  • 15 sizes


The FLUDEX coupling’s operating conditions can be monitored with an Electronic Operating Control system, and the coupling housing includes safety features such as thermal operation control and fusible safety plugs to prevent overload pressure and overheating.


Main Advantages

  • Starting aids and overload protection in tough applications,
  • Limit start and maximum torque in the drive train
  • Reduce restoring forces through damping and separation of rotary oscillation
  • Operate wear-free by transmitting torque through fluid movement as accelerated by radial blades according to the Föttinger principle


Customer Benefits

  • Soft and shock-free starting of machines and conveyor systems
  • Torque transmission without wear, therefore providing for startup of internal combustion engines while connected to load
  • Torque limitation during start-up and overload
  • Acceleration of large masses
  • Protection against load peaks resulting from frequent switching and reverse operation
  • Excellent decoupling of vibrations and shock damping
  • Torsional vibration decoupling
  • Small operating slip at nominal load
  • Suitability for potentially explosive environments
