The AA10VSO180LA7DS/32R-VSD72U00E-SO413 pump belongs to the A10VSO Variable Pumps series produced by Bosch Rexroth and supplies adjustable hydraulic flow for automation circuits. Its displacement is 180 cm³ per revolution, determining how much oil moves with each shaft turn. The drive end is configured for clockwise rotation, allowing direct coupling to standard right-hand engines and motors. Shaft speed is permitted up to 1800 rpm, a limit set to keep internal pistons within safe inertial forces. At that peak speed the unit can deliver 324 L/min, supporting high-demand actuators. Power input reaches 151 kW when the pump supplies 280 bar at 1800 rpm, information needed when sizing prime movers. The related output torque equals 802 Nm at the same pressure, guiding coupling and shaft selections. Continuous operation is allowed at 280 bar, while 350 bar can be applied for short duty cycles where extra force is required.
The housing tolerates a case pressure of 2 bar absolute, ensuring shaft seals retain leakage oil without extrusion. An internal volume of 2.7 L provides space for oil accumulation and helps dissipate heat generated by the rotating group. The suction side must see at least 0.8 bar absolute to prevent cavitation during high flow demand. That inlet is furnished with a SAE 2 1/2-inch flange compliant with ISO 6162-1, so large hoses can be attached without custom adapters. Delivery ports are sized at SAE 1 1/4-inch according to ISO 6162-2, matching common return and actuator lines. Pilot control oil is connected through a M14 × 1.5 threaded port, enabling remote displacement regulation. Excess case oil exits a M33 × 2 drain port that accepts standard metric fittings for safe return to tank. The pump is supplied without a through drive, meaning no secondary pump or accessory can be mounted in tandem.
