FLUDEX Fluid Coupling

• Hydrodynamic fluid coupling
• Nominal output from 1.2 kW up to 2,500 kW with 15 sizes
• Temperature range: from –40 °C to +50 °C‍

‍

Fluid couplings operate according to the Föttinger principle. The coupling parts on the input and output side are not mechanically connected and are therefore wear-free. The torque is transmitted by the fluid movement in the coupling, accelerated by the radial blades. Our film illustrates the Föttinger principle as well as the operating principle of the FLUDEX coupling.‍‍

‍Your benefits at a glance

• Soft and shock-free starting of machines and conveyor systems
• Torque transmission without wear allows internal combustion engines to start up with a connected load
• Torque limitation during start-up and in the case of overload protects coupled system components
• Acceleration of large masses without using oversized motors
• Protection of the drive against load peaks due to frequent switching procedures and reverse operation
• Excellent decoupling of vibrations and shock damping
• Largely torsional vibration decoupling in vibration-endangered drives
• Small operating slip of the coupling at nominal load (approx. 2%)
• Suitable for use in potentially explosive environments; certified according to 2014/34/EU (ATEX)

Did you know?

‍The specified operating conditions of a FLUDEX coupling can be monitored by a non-contact and maintenance-free Electronic Operating Control (EOC) system. A thermal operation control device and fusible safety plugs in the coupling housing provide additional protection against overheating and overload pressure.
