The AA10VSO100DR/31R-VKC62N00 pump is produced by Bosch Rexroth as part of the A10VSO Variable Pumps series and supplies adjustable flow for hydraulic automation systems. A displacement of 100 cm³/rev fixes the fluid volume moved per shaft rotation, and a delivery rate of 200 L/min at nominal speed supports medium-to-high flow circuits. Shaft power reaches 93 kW at 280 bar so the prime mover must be selected for that load. Continuous operation is allowed at 280 bar, while brief peaks to 350 bar cover overload events. Output torque climbs to 445 Nm at full pressure and displacement, guiding coupling selection. The permitted speed at full displacement is 2000 rpm, which establishes overall flow limits and noise characteristics.
With the swashplate partially retracted the unit can run up to 2400 rpm, extending speed range without exceeding thermal capacity. Clockwise shaft rotation is defined for correct installation. A 2.2 L case volume collects leakage oil for cooling and pressure balance, and a rotary group inertia of 0.0167 kg·m² affects acceleration demands in servo loops. The 2 1/2 in suction port (ISO 6162-1) permits low inlet velocity to curb cavitation, while the 1 1/4 in pressure port (ISO 6162-2) connects to high-pressure lines. A 7/16-20 UNF pilot port allows remote pressure control devices. FKM seals withstand hot hydraulic oil and common fluid additives, and the bare pump weighs 49.5 kg, influencing mounting and service handling.
