The Bosch Rexroth AA4VG71HD3DMT1/32L-NSF52F041D-S (R902249571) is a state-of-the-art high-pressure pump designed for closed circuit applications, specifically tailored for the US market with its SAE version. This pump features an integrated boost pump that ensures a reliable boost and pilot oil supply, enhancing the overall efficiency of the hydraulic system. The smooth change of flow direction as the swashplate moves through the neutral position illustrates the precision engineering inherent in this model. With a size that allows it to handle demanding tasks, this Bosch Rexroth pump operates at a nominal pressure of bar and can withstand maximum pressure peaks up to bar. Its high-pressure relief valves are noteworthy for their integrated boost function, which contributes to the pump's robust performance in challenging conditions. Additionally, it comes standard with an adjustable pressure cutoff, offering users greater control over their hydraulic systems' operation. The AA4VG71HD3DMT1/32L-NSF52F041D-S also includes a boost pressure relief valve for added safety and system protection. A significant feature is its through-drive capability, which permits the mounting of additional pumps up to the same nominal size, thus providing flexibility in configuring complex hydraulic systems. The swashplate design of this Bosch Rexroth pump is a testament to its adaptability and capability to deliver consistent performance across various applications. Overall, this model is engineered to meet the rigorous demands of closed circuit systems where efficiency and reliability are paramount.
