The A10VO28ED71/52R-PSC62N00P pump belongs to the A10VSO Variable Pumps series and is manufactured by Bosch Rexroth for hydraulic automation circuits that require variable flow. The unit displaces 28 cm³ per revolution, allowing proportional delivery matched to actuator demand. When driven at 1800 rpm with full displacement, it supplies 50 L/min, and raising speed to its rated 3000 rpm lets the flow reach 84 L/min. Continuous duty is supported by a nominal pressure of 280 bar, while a peak limit of 350 bar covers brief transients. At the nominal setting the shaft must transmit 125 Nm, which equates to 39 kW, so prime movers can be sized accurately. These flow, pressure, torque, and power values define a compact source of hydraulic energy for industrial machinery.
The permissible speed rises to 3600 rpm when displacement is reduced, offering extra headroom during rapid cycle changes. A moment of inertia of 0.0017 kg·m² lowers starting torque, and the assembly weight of 15 kg eases handling during installation. Fluid enters through a SAE J518 1 1/4 in inlet port and exits the pressure side via a SAE J518 3/4 in connection, while case drainage is handled by an ISO 11926 3/4-16 UNF-2B port that returns leakage to tank. Drive power is transferred through a 7/8 in 13-tooth 16/32 DP splined shaft compatible with standard couplings. The housing requires 0.7 L of oil at filling to ensure internal lubrication and air removal before start-up. These mechanical and fluid features combine to simplify mounting and support reliable service in automated hydraulic systems.
