The AA11VLO130DRS/10R-NSD62N00 variable pump is part of the A11V Variable Pumps series from Bosch Rexroth and supplies pressurized hydraulic oil to automated actuators. Its geometric displacement is 130.0 cm³ per revolution, so each shaft turn moves a precise fluid volume. When the pump operates at nominal speed with the displacement set to maximum, it delivers 325 l/min, enabling high flow circuits. Continuous duty is supported at 350 bar, while a permissible peak of 400 bar covers transient system loads. The DRS control provides pressure and load sensing to adjust displacement according to demand. Rotation is clockwise, matching right-hand drive layouts, and the shaft can reach 2500 rpm without overspeed. A rotor inertia of 0.0337 kg·m² influences start-up acceleration and drive selection.
Internal case volume is 2.9 L, allowing adequate oil for bearing lubrication and case flushing. Installation uses an SAE J744 four-hole flange, streamlining interchange with standard prime movers. An NBR elastomer combined with an FKM shaft seal keeps the housing sealed against fluid leaks. The pump weighs 72 kg without a through-drive, so mounting structures must support that mass. The drive shaft can accept 1640 N·m, and at maximum displacement with 350 bar the hydraulic torque load is 724 N·m, leaving margin for mechanical safety. At the same operating point it absorbs 190 kW of power, a value that defines motor sizing.
