The fluid couplings by KTR Systems are hydrodynamic couplings for hydrodynamic power transmission according to the Foettinger principle.
Originally the operating principle of the fluid coupling is based on the hydrodynamic torque converter patented by Hermann Foettinger (1877 - 1945) (Foettinger principle):The inertia forces are transmitted via a flowing fluid (e. g. oil) with the driving and driven side being mechanically separated from each other.
With this operating principle the mechanically driven pump wheel accelerates the fluid in the working area via radially arranged inner blades. The rotation energy of the circulating fluid absorbed by the blades of the turbine wheel accelerates the wheel while the resulting mechanical power is dissipated on the driven side.

Types of fluid couplings/hydraulic couplings
Our product portfolio of fluid couplings includes a large number of product types. No matter whether compact variants with very smooth starting or radially dismountable, displacement-friendly types are required - we can provide the right coupling, please contact us.
