Turbostart Hydrodynamic Coupling

Smooth start-up and overload protection

The TURBOSTART Hydrodynamic Coupling is a power transmission component designed for the gradual start-up of high-inertia machines driven by asynchronous electric motors or diesel engines. Consisting of two impellers with symmetrical blading (pump and turbine), it transmits torque through oil circulation, eliminating any rigid mechanical connection between the motor and the driven machine.

The Turbostart hydrodynamic coupling ensures:

• Smooth start-up of the driven machine
• Reduction of current peaks during start-up (up to 50%)
• Protection against overloads and torsional vibrations
• Possibility to size the motor based on actual absorbed power
• Automatic load balancing in multi-motor systems

Available versions: in-line (L/S, L/MU, L/E), pulley-mounted (PF, PT, PI, PC) and with flanges for gear couplings (CF). All versions can be equipped with the R partial draining device for even smoother control of start-up torque.

Suitable for use in potentially explosive atmospheres.

Power range: from 0.37 to 1,470 kW
