The complete fluid coupling range.

One hydrodynamic principle, engineered into four product families and a wide choice of models — for industrial and automotive drives up to 6000 KW.

Fluidomat constant-fill fixed-speed fluid coupling
Constant fill

Fixed-speed couplings

Soft no-load motor starting, adjustable starting torque from 120%, overload protection and vibration damping at constant running speed.

  • SM, HF, SMP, Alfa-P & T-12 models
  • Steel-body SF, CBSF & WF variants

Fluidomat variable-speed scoop-control fluid coupling
Variable speed

Scoop-control couplings

Stepless speed variation up to 5:1 from a fixed-speed motor — turning fan and pump speed control into significant energy savings.

  • SC scoop-control range to 6000 KW
  • FNCT fill-control & FNIC for IC engines
