The Bosch Rexroth AA4VG125HD3DT1/32L-NSF52F071D-S (R902125372) is a high-performance axial piston variable pump with a swashplate design for hydrostatic drives in an open circuit. This particular model incorporates an integrated boost pump, which serves the dual purpose of supplying boost and pilot oil, ensuring consistent and efficient operation. The flow direction of the pump transitions smoothly as the swashplate moves through the neutral position, which enhances the control and responsiveness of the system. Equipped with high-pressure relief valves that feature an integrated boost function, this Bosch Rexroth pump ensures safety by regulating pressure within the hydraulic system. Additionally, it includes an adjustable pressure cutoff as a standard feature, providing further protection against overpressure conditions. The model also boasts a boost pressure relief valve for added system security. Designed for versatility, the AA4VG125HD3DT1/32L-NSF52F071D-S offers a through-drive option that allows for the mounting of additional pumps up to the same nominal size. This capability makes it suitable for applications requiring multiple pump configurations or increased hydraulic power. The wide range of controls available with this model enables customization to meet specific application needs. Its robust construction and advanced features make it suitable for demanding applications that require reliable hydraulic power and precise control. The Bosch Rexroth AA4VG series is known for its durability and efficiency in various applications, making this model an excellent choice for those seeking a high-quality axial piston variable pump solution.
