The Bosch Rexroth AA4VG125EP4DM1/32L-NSF52F001PT-S (R902123135) is a high-pressure axial piston pump designed for applications in closed circuits. This model features an integrated boost pump, which serves both to supply boost and pilot oil, ensuring that the flow direction changes smoothly when the swashplate is transitioned through the neutral position. The pump is equipped with high-pressure relief valves that incorporate a boost function and come with an adjustable pressure cutoff as a standard feature. Additionally, the AA4VG125EP4DM1/32L-NSF52F001PT-S includes a boost pressure relief valve and offers through-drive capabilities, allowing for the mounting of additional pumps up to the same nominal size. This versatility makes it suitable for complex hydraulic systems requiring multiple pump configurations. The pump operates at a nominal pressure of bar and can withstand maximum pressure peaks of bar, highlighting its robustness for demanding applications. Designed with a swashplate mechanism, this Bosch Rexroth pump ensures efficient conversion of mechanical power into hydraulic energy, providing precise control over fluid flow within the system. The SAE version is tailored specifically for the US market, adhering to relevant standards and specifications required for operation within this region. The AA4VG125EP4DM1/32L-NSF52F001PT-S stands out due to its reliability and performance in high-pressure environments, making it an optimal choice for industrial applications requiring meticulous fluid control under rigorous conditions. Its construction reflects Bosch Rexroth's commitment to engineering excellence and innovation in hydraulic technology.
