The AA11VLO190EP2G/11L-NTD62K17P variable pump belongs to the A11V Variable Pumps series from Bosch Rexroth. It is designed to supply pressurized fluid to hydraulic actuators in mobile or industrial automation circuits. The geometric displacement of 193.0 cm³ per revolution defines how much oil is moved each shaft turn, allowing predictable flow calculation. A maximum rotational speed of 2500 rpm permits high-duty cycles without overspeeding the rotating group. The rotation direction is counter-clockwise, so drive couplings must match that orientation. The unit tolerates a maximum pressure of 400 bar, supporting heavy load circuits, while a nominal pressure rating of 350 bar establishes the continuous working limit. At that nominal pressure the pump can deliver 281 kW to the hydraulic system, and the corresponding hydraulic torque requirement is 1075 Nm on the input shaft. A 1 3/4-inch 13-tooth 8/16DP through-drive hub (code K17) permits tandem mounting or the attachment of auxiliary pumps.
For flow management the pump reaches 483 l/min at 2500 rpm and full displacement, providing sufficient volume for large cylinders or multiple functions. The internal case holds 3.8 l of oil, which balances lubrication with heat removal for the swashplate and bearing set. When a charge pump is used, the suction line must maintain at least 0.6 bar absolute and may not exceed 2 bar absolute, securing cavitation-free inlet conditions. The EP2 electro-proportional control operates on 24 V and draws 600 mA, so drive electronics can be sized accordingly; its coil has a nominal resistance of 22.7 Ω to ensure correct current regulation. Overall weight without a through-drive attachment is 104 kg, allowing frame design and mounting hardware to be specified for safe handling. These parameters complete the hydraulic and electrical profile required for integrating the AA11VLO190EP2G/11L-NTD62K17P pump into automated power units.
