The Bosch Rexroth AA4VG71DGDMT1/32L-NSF52F001D-S (R902120429) is a state-of-the-art axial piston variable pump that stands out for its integration of a boost pump for boost and pilot oil supply. This feature ensures a reliable and consistent performance, particularly in applications where smooth flow direction changes are critical when the swashplate moves through the neutral position. The high-pressure relief valves, which come with an integrated boost function, enhance the safety and efficiency of the system by protecting it from pressure spikes. Equipped with an adjustable pressure cutoff as standard, this pump offers additional control over the operational parameters, allowing for customization based on specific application needs. The inclusion of a boost pressure relief valve further contributes to the system's stability and longevity. One of the notable capabilities of this model is its through-drive design, which allows for the mounting of additional pumps up to the same nominal size. This modular approach provides flexibility in system design and expansion possibilities without compromising performance. The AA4VG71DGDMT1/32L-NSF52F001D-S is engineered with a swashplate design that ensures high efficiency and reliability in operation. This pump is suitable for various applications that demand precise control and adaptability in hydraulic systems, thanks to its wide range of controls and robust build quality. Bosch Rexroth's commitment to innovation and excellence is evident in this advanced hydraulic component, designed to meet the rigorous demands of modern machinery and industrial applications.
