The A10VSO140DFLR/31L-VPB12N00 variable pump is manufactured by Bosch Rexroth for the A10VSO Variable Pumps series and supplies adjustable oil flow in hydraulic automation. It employs DFLR pressure, flow, and power control so system demand sets the swashplate angle. The unit displaces 140 cm³ per revolution, and it turns counter-clockwise to match standard drive engines. Oil is directed from port S to port B, permitting consistent circuit layout. A nominal pressure rating of 280 bar defines continuous duty limits, while control becomes active at 80 bar to keep the load compensated. When operated at the maximum swashplate angle, shaft speed must not exceed 1800 rpm, a point where the pump can deliver 252 l/min to downstream actuators.
For short load peaks the pump tolerates 350 bar, providing reserve above the nominal rating. With the displacement reduced, allowable speed rises to 2100 rpm to maintain flow with a smaller geometric volume. The inlet side requires at least 0.8 bar absolute to prevent cavitation, and the case drain line must stay below 2 bar to protect shaft seals. At 280 bar the shaft must transmit 623 Nm of torque, supported by a moment of inertia of 0.574 lb·ft² that influences acceleration. Power demand reaches 118 kW under 280 bar at 1800 rpm, and the assembled unit weighs 60 kg for installation planning.
