Hydrodynamic couplings belong to the group of hydrodynamic power transmission devices. The power transmission is done by mass forces of the operation liquid according to the "Frottinger Prinzip".The impeller pump absorbs the mechanical power of the drive and increases the energy of the circulating operating liquid. The turbine wheel takes energy away from the operating liquid and outputs mechanical power. There is not any fixed connection between both wheels. Slight power losses, caused by the for the power transmission necessary slippage, will be transformed to heat. The permissible ambient temperature range of the hydrodynamic coupling in standard design is between -25℃ ~ +40℃ (other values on request).
