Why a gerotor?
Numerous applications in hydraulic and lubrication systems just require the circulation of the fluid. In such cases low noise emissions and low pressure ripples are more important than highly efficient transmission of energy.
The gerotor is the ideal principle for such applications. The displacement mechanism consists of the inner and the outer rotor. The number of teeth of the inner rotor is always one less then the outer rotor. The rotation of the gerotor generates chambers of changing volumes between the inner and outer rotor. The variation of the volume follows a sinus curve with low amplitude resulting in a proportional flow with very low pressure ripples.
The relation between number of teeth, diameter and width of the gerotor has been chosen with the target for a very compact design featuring small physical dimensions, low weight and minimal loss in efficiency. The low differential of revolutions between the inner and outer rotor provides low vibration and long life. The internal design of the pump head reduces the loss of pressure and ensures good suction performance
Why complete pump units?
Each additional component increases the physical volume of a system and results in higher space consumption and cost. Therefore the main target for the BFP-series was set to provide a compact solution. With the models BFP 5 up to 40 the gerotor is directly driven by the motor shaft. The larger pumps BFP 60 and 90 are driven with a special coupling where the motor shaft is integrated. This concept results in additional benefits like good cooling and lubrication.
