The KFBD serie Fluid Couplings are used on all types of 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 machine.

When you drive through KFBD coupling you profit by these Basic Benefits.

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
Mechanical connection is eliminated; power and torque are transmitted entirely through mass and velocity of fluid. The result is a smooth sustained flow of power minus the shocks and strains which with mechanical drives cut equipment life.

3 – Prevents transmission of shock loads
Fluid Couplings protects both driving and driven equipment by smoothing out shock loads and preventing them from striking solid resistance.

4 – Assures damping effects
Torsional vibrations from engine are drastically dampened by Fluid Coupling making longer life of entire transmission life.

5 – Transmits full input torque
The patented Transfluid Circuit design delivers output torque always equal to input torque. The engine can turn at its max torque-rpm even when driven is at stall.

6 – High radial load capability
The KFBD serie has also been designed for application requiring pulley installation particularly on heavy duty service.
