Annular gear pump/motor

Adjustment of the output volume of a pump or the displacement of a motor by hand via a spindle. Once the desired value has been set, the pump/motor continues to work as a fixed displacement unit.

Power drawn at the shaft of a hydraulic pump at a specific point in time or under specific load conditions. It differs from the hydraulic power by the sum of the pump losses ( volumetric efficiency, hydr

controllers, reduces or limits the pump delivery flow on reaching an upper adjustable pressure to prevent the pressure-limiting valve triggering and the related power loss. Pump controls in hydrostatic propulsion

in a hydraulic pump from the suction phase to the pressure phase and vice-versa. Their number (frequency) depends on the number of displacement units and the rotation speed of the pump.

Power of a device (pump, motor, valve ) within defined parameters.

hydraulic motor or cylinder speed or stroke rotation speed is bound by the pump delivery flow . Due to this current feed, a pump can only ever actuate one drive unit. It is only possible to drive several

with fresh oil in a closed circuit. For this purpose, there is a feed circuit from the Charge pump (flushing pump), a Filter and a cooler as well as two for supply and the flush valve for removal.

Displacement volume of a hydrostatic pump or displacement volume of a hydrostatic motor.
