TRANSFLUID KFBD: Constant fill fluid couplings

Hydraulic coupling for diesel engines – starter

The KFBD series Constant Fluid Couplings are used on all industrial equipment driven by internal combustion engines up to 500 kW. By transmitting power through a fluid, they improve overall performance and protect both driving and driven machines.


  1. Frees engine during heavy starts
    During heavy starts and sudden running load increases, engine lugging is prevented. The Fluid Coupling simply “slip” while it smoothly picks up the load.
  2. Provides smoothly drive
    The mechanical connection is eliminated; power and torque are transmitted entirely through the fluid’s mass and velocity. The result is a smooth, sustained flow of energy minus the shocks and strains which, with mechanical drives, cut equipment life.
  3. Prevents transmission of shock loads
    Fluid Couplings protect both driving and driven equipment by smoothing out shock loads and preventing them from striking solid resistance.
  4. Assures damping effects
    Torsional vibrations from the engine are drastically dampened by Fluid Coupling, increasing the entire transmission’s life.
  5. Transmits full input torque
    The patented Transfluid Circuit design delivers output torque always equal to the input torque. The engine can turn at its max torque-rpm, even when driven is at stall.
  6. High radial load capability
    The KFBD hydraulic coupling series has also been designed for applications requiring pulley installation, particularly heavy-duty service.
