The AA10VO60DFR/52L-VSC62N00 pump belongs to the A10VSO Variable Pumps series produced by Bosch Rexroth and supplies variable displacement flow for hydraulic automation where precise pressure control is required. Its shaft turns counterclockwise, matching drive trains that share this rotation direction. Flow moves from port S to port B, defining circuit layout for open-loop designs. Service ports are located on the side under code 62 N00 to simplify compact manifold assembly. An inlet absolute pressure limit of 30 bar prevents cavitation when the reservoir is pressurized, while the nominal working limit of 280 bar allows continuous high-duty operation. The integrated pressure controller is also set for 280 bar so the circuit is automatically relieved at that value. A peak pressure rating of 350 bar covers short overload events without damage, and case-drain pressure must stay below 2 bar absolute to protect seals and reduce internal leakage.
A minimum operating viscosity of 10 mm²/s maintains oil film strength during normal service, and the pump tolerates short-term viscosity up to 1600 mm²/s for cold starts. Fluid temperature can fall to −40 °C for winter operation and rise to 115 °C during heavy loading without impairing components. Cleanliness must meet ISO 4406 class 20/18/15 so particulate wear on the piston assembly remains low. Pilot fluid consumption does not exceed 1.2 gpm, which limits control losses and eases heat load on the reservoir. The pilot port X is threaded 7/16-20 UNF-2B, allowing connection to common hydraulic fittings in industrial panels.
