The Bosch Rexroth AA4VG125EP4D1/32L-NSF52N001EP-S (R902205647) is a high-pressure axial piston pump designed for closed circuit applications. This pump features an integrated boost pump, which serves both as a supply for boost and pilot oil, ensuring consistent performance and reliability. The smooth flow direction transition when the swashplate moves through the neutral position highlights the pump's precision engineering. Equipped with high-pressure relief valves that incorporate a boost function, this model ensures safety and optimal operation under various conditions. The pressure relief valves are complemented by an adjustable pressure cutoff, now a standard feature, adding to the pump's versatility and control. For added functionality, the AA4VG125EP4D1/32L-NSF52N001EP-S includes a boost pressure relief valve and offers through-drive capability. This allows for the mounting of additional pumps up to the same nominal size, expanding its application potential without compromising space or complexity. The swashplate design of this Bosch Rexroth pump underscores its efficiency in operation, tailored specifically for demanding tasks that require precise hydraulic control. With its nominal pressure of bar and maximum pressure bar capabilities, it is engineered to meet rigorous performance standards. Finally, this particular model is tailored for the US market with an SAE version configuration, ensuring compatibility with industry standards in North America. Its robust design and advanced control options make it suitable for a wide range of applications that require reliable high-pressure hydraulic power in closed circuits.
