The Bosch Rexroth AA4VG125EP4DT1/32L-NSF52F001BP (R902217991) is a high-pressure axial piston pump designed for applications within closed circuits. This particular model is tailored for the US market, featuring an SAE version that ensures compatibility with standard American equipment. The pump boasts an integrated boost pump, which serves both to provide a boost and pilot oil supply, ensuring reliable and efficient operation. The AA4VG125EP4DT1/32L-NSF52F001BP is engineered to facilitate smooth flow direction changes as the swashplate moves through the neutral position. It comes equipped with high-pressure relief valves that incorporate a boost function, enhancing the safety and performance of the system. Moreover, this model includes an adjustable pressure cutoff as a standard feature, allowing for precise control over the operational parameters. A notable feature of this Bosch Rexroth pump is its boost pressure relief valve, which plays a critical role in maintaining optimal pressure levels within the system to prevent potential damage due to pressure spikes. The unit also offers versatility through its through-drive capability, enabling the mounting of additional pumps up to the same nominal size directly onto this pump without requiring extra coupling mechanisms. Designed with a swashplate configuration, this axial piston pump is capable of handling nominal pressures of up to bar and can withstand maximum pressures up to bar. Its robust design ensures it can meet the rigorous demands of various hydraulic applications while maintaining efficiency and longevity. The AA4VG125EP4DT1/32L-NSF52F001BP stands out for its reliability in closed-circuit operations and its adaptability in integrating with other hydraulic components for enhanced system functionality.
