The AA10VO100DFR1/31L-VUC61N00 pump belongs to the A10VSO Variable Pumps series and is manufactured by Bosch Rexroth for hydraulic automation where controllable oil delivery is required. Its geometric displacement is 100 cm³ per revolution, giving designers a direct way to convert shaft speed into theoretical flow. When running at 1800 rpm and set to maximum displacement, the pump supplies 180 L/min, while increasing speed to 2000 rpm raises flow to 200 L/min. The housing is rated for 350 bar, so system components must be selected to tolerate that pressure. To drive the unit at 100 bar the prime mover must generate 159 Nm, a value that assists in coupling selection. Oil enters through a 2 1/2 in suction port compliant with ISO 6162-1, and the complete assembly weighs 49.5 kg, which influences mounting and support structure design.
During transient conditions the shaft may accelerate to a maximum of 2400 rpm provided displacement is reduced below the maximum setting. Continuous operation is anchored at a rated speed of 2000 rpm, and at this speed with 280 bar load the pump demands 93 kW from the driving motor. Torque requirements climb to 445 Nm at that same pressure, so torsional components must be sized accordingly. System piping connects to a 1 1/4 in pressure outlet specified by ISO 6162-2; excess leakage returns through a drain port cut with a 1 1/16-12 UNF-2B thread, and control signals are routed into a 7/16-20 UNF-2B pilot port. An internal case volume of 2.2 L accommodates cooling fluid that lubricates rotating groups and manages heat during prolonged duty cycles.
