AA10VSO100DR/32R-VKD72U99

The AA10VSO100DR/32R-VKD72U99 pump is produced by Bosch Rexroth within the A10VSO Variable Pumps series. It provides variable displacement for hydraulic automation systems that require closely regulated flow. A geometric displacement of 100 cm³ per revolution defines the fluid volume moved with each shaft turn, guiding circuit dimensioning. The rated speed at maximum displacement is 2000 rpm, setting the continuous operating limit and influencing drive selection. At that point the pump can absorb 93 kW, so the prime mover must be sized to match this power demand. A nominal pressure rating of 280 bar identifies the continuous working load the housing can withstand. Suction oil enters through an SAE J518 2 1/2-inch flange, minimizing inlet restriction, while the case volume of 2.2 L ensures internal lubrication and heat dissipation. A moment of inertia of 0.0167 kg·m² affects acceleration during start-up, and a bare weight of 49.5 kg influences mounting structures.

When driven at 1800 rpm the pump delivers a steady 180 L per minute, supplying cylinders and motors in medium-capacity machines. The maximum flow rises to 200 L per minute at the nominal operating point, allowing brief increases in actuator speed without changing displacement. A permissible peak speed of 2400 rpm broadens the range for short-term high-flow demands. The maximum pressure limit of 350 bar specifies the highest transient load the unit can safely accept. Drive torque is 159 Nm at 100 bar and increases to 445 Nm at 280 bar, so gearbox and coupling components must accommodate these values. Discharge oil leaves through an SAE J518 1 1/4-inch pressure port that aligns with standard piping. A 7/16-20 UNF-2B pilot port labeled X supplies control oil to adjust displacement remotely. Together these flow, speed, pressure, torque, and connection parameters define how the pump integrates into automated hydraulic circuits requiring variable delivery and reliable pressure control.
