The AA10VO100DFR/31L-VUC62N00 pump belongs to the A10VSO Variable Pumps series from Bosch Rexroth and supplies adjustable oil flow for hydraulic automation tasks such as actuating cylinders or motors. Its geometric displacement is 100 cm³ per revolution, establishing the volume transferred during each shaft turn. When driven at 1800 rpm with the displacement set to maximum, it delivers 180 L/min, while increasing speed to 2000 rpm raises output to 200 L/min so circuits can be sized for higher demand cycles. A nominal pressure rating of 280 bar defines continuous load capacity, and a peak pressure limit of 350 bar covers short transient events. The DFR control is factory set for a 14 bar differential, permitting load-sensing regulation between pump outlet and control line. At 280 bar the shaft develops 445 N·m, and the power drawn reaches 93 kW at 2000 rpm, figures used for motor selection and coupling design.
Maximum drive speed is 2000 rpm at full displacement, whereas operation at reduced displacement allows up to 2400 rpm, giving designers latitude to balance flow against mechanical stress. Inlet absolute pressure must stay between 0.8 bar and 30 bar to prevent cavitation or seal overload, and the case drain pressure is limited to 2 bar to protect shaft seals. A 2.2 L case volume stores leakage oil and aids heat dissipation inside the housing before fluid returns to the reservoir. The rotating group presents a drive-axis moment of inertia of 0.0167 kg·m², data required for acceleration calculations; this low inertia benefits start-stop duty cycles found in servo-controlled presses. Dry weight is 45 kg, influencing mounting hardware and service handling. Together these parameters set the operational envelope and installation needs of the AA10VO100DFR/31L-VUC62N00 within hydraulic manifolds, power units, and integrated machine frames.
