The A10VSO10DR/52L-PUC64N00 pump belongs to the A10VSO Variable Pumps series and is produced by Bosch Rexroth for hydraulic automation that demands adjustable flow. A DR pressure controller adjusts outlet pressure directly, eliminating the need for external valves. The pump displacement is 10.5 cm³ per revolution, defining the fluid volume moved each shaft turn. When the shaft turns at 1500 rpm with maximum displacement, the unit delivers 15 l/min to downstream components. Continuous operation at full displacement is limited to 3600 rpm, while intermittent peaks can reach 4320 rpm if displacement is reduced. A nominal pressure rating of 250 bar governs routine loading, and a maximum pressure of 315 bar accommodates short-duration spikes. System stability requires at least 10 bar absolute on the high-pressure side, and the inlet must stay above 0.8 bar absolute to avoid cavitation.
At the catalog nominal speed, full displacement raises flow to 37 l/min, which supports fast actuator cycles. An internal case volume of 0.2 l stores leakage oil and keeps bearings lubricated. Shaft loading is limited to a radial force of 250 N at half diameter, guiding coupling or pulley selection. Rotation is counterclockwise when viewed from the shaft end, ensuring alignment with the chosen prime mover. Suction pressure may rise to 5 bar absolute without harming the inlet seal, allowing flooded-tank installations. When the pressure drop is 250 bar at full displacement, the drive must supply 42 Nm of torque and approximately 16 kW of power, figures used to size electric motors or engines. These limits help designers balance speed, flow, and mechanical stress in compact hydraulic systems.
