The AA10VSO100DFR1/31R-VPA12N00 variable pump is manufactured by Bosch Rexroth for the A10VSO Variable Pumps series. It serves as an adjustable axial-piston source that matches output flow to actuator demand in hydraulic automation systems. The fixed geometric displacement of 100 cm³ per revolution (6.10 in³/rev) defines the volume delivered on each shaft turn, while a flow of 47.6 gpm (180 L/min) at 1800 rpm establishes baseline capacity for common electric motor drives. At the rated speed the pump can reach 52.8 gpm (200 L/min), offering additional margin when full output is required. Continuous operation is limited to a nominal pressure of 4100 psi (280 bar), and short-term peaks are permissible up to 5100 psi (350 bar) to handle transient load spikes. The maximum speed is 2000 rpm at full displacement; reducing the displacement allows operation up to 2400 rpm so that smaller motors can still achieve the target flow. A housing volume of 0.580 gal (2.2 L) contains leakage oil for bearing lubrication and aids thermal stabilization during prolonged duty.
The pump requires an absolute inlet pressure of at least 12 psi (0.8 bar) to prevent cavitation at the swashplate group. The suction port is sized at 2 1/2 in according to ISO 6162-1, enabling low-restriction plumbing from the reservoir, while the working port B uses a 1 1/4 in ISO 6162-2 interface for pressure delivery to the circuit. A drain line connection with 1 1/16-12 UNF-2B threads lets leakage oil return to tank without back-pressure. The integrated flow controller maintains a standard differential pressure of 200 psi (14 bar) across the load, permitting stable flow regulation as system demand varies. Internal case pressure must stay below 30 psi (2 bar) so shaft seals are not overstressed. When the pump operates at 280 bar and maximum displacement, the input shaft must withstand 328 lb-ft (445 Nm) of torque, a figure useful for sizing couplings and prime movers. The assembly weighs 109 lb (49.5 kg), which informs mounting hardware selection and facilitates handling during maintenance.
