FL-SP Hydrostatic Drive Coupling

The flange coupling FL-SP has been developed especially for
hydrostatic pump drives for the connection of internal combustion
engines to hydraulic pumps.
Due to the torsionally stiff design critical resonances can be shifted
into the range above the operating speed. This enables a sub
critical operation of the drive without passing through detrimental
torsional vibration amplitudes.
The hydrostatic drive applications often demand compact coupling
design and axial pluggability. The FL-SP coupling is designed to
meet these requirements.
The FL-SP coupling consists of a clamping hub and a plastic-steel
composite flange, which are connected to each other as a plug-in
connection. The hub ensures a backlash-free clamping connection
on the pump shaft. The coupling flange is available in various SAE
sizes.
