21KFBD/ Eagle



21KFBD with special adaptor and temp. switch (Eagle Spec)-SAE #1 Housing with 14” Flywheel, Maximum 510 Horse Power at 1800RPM.

The KFBD series 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 been also desigend for application requiring pulley installation particularly on heavy duty service.
