The Bosch Rexroth AA4VG71HD3D2/32R-NTF52F071P-S (R902275541) is an advanced axial piston variable pump that embodies cutting-edge hydraulic engineering. This model features an integrated boost pump which serves a dual purpose: it ensures a consistent boost and pilot oil supply, and it facilitates smooth flow direction changes as the swashplate transitions through the neutral position. The high-pressure relief valves are designed with an integrated boost function and come standard with an adjustable pressure cutoff, enhancing the safety and efficiency of operations. Additionally, the AA4VG71HD3D2/32R-NTF52F071P-S is equipped with a boost pressure relief valve to provide further system protection. Its through-drive capability is particularly notable, allowing for the mounting of additional pumps up to the same nominal size, which can be extremely beneficial in complex hydraulic systems requiring multiple pump configurations. The large variety of control options available with this model ensures versatility for different application requirements. Built on a swashplate design, this variable pump is engineered to meet the demands of high-performance hydraulic systems where reliability and durability are paramount. Whether used in mobile or industrial applications, this Bosch Rexroth variable pump stands out for its robustness and adaptability to various operational conditions.
