The AA10VSO180LA6DS/32R-VSD72U00E-SO413 pump is produced by Bosch Rexroth and belongs to the A10VSO Variable Pumps series for closed-loop hydraulic automation circuits. It operates with clockwise rotation, so shaft alignment and plumbing must follow standard right-hand orientation. The unit has a displacement of 180 cm³ per revolution, defining the volume of fluid delivered each shaft turn. At 1500 rpm the pump supplies 270 l/min, matching medium-speed machine tools that need steady flow. When driven up to its maximum speed of 1800 rpm, flow rises to 324 l/min for applications that demand short-term peak capacity. A nominal pressure rating of 280 bar supports continuous duty, while a maximum pressure limit of 350 bar allows brief overload cycles without damage. The housing attaches with an ISO 3019-2 four-hole flange, streamlining interchange with standardized motor adapters.
The pump develops 151 kW at 280 bar and 1800 rpm, giving power density suitable for high-output injection presses. Under the same conditions shaft torque reaches 802 Nm, which dictates coupling and drive shaft selection. Fluid enters through a 2-1/2 in ISO 6162-1 suction port, reducing inlet velocity and cavitation risk. Delivery exits at the ISO 6162-2 1-1/4 in working port B, ensuring compatibility with SAE split-flange plumbing. Control oil connects at pilot port X threaded M14 × 1.5, providing a dedicated channel for remote pressure signaling. FKM seals are fitted to resist high temperature hydraulic oils and maintain leak-free operation. There is no through drive, so the unit must be installed as the terminal component on the drive train.
