The Bosch Rexroth AA4VG90HD3DM1/32L-NSF52F021D-S (R902122884) is a high-performance axial piston variable pump designed for hydrostatic drives in closed circuits. This pump features an integrated boost pump that provides both boost and pilot oil supply, ensuring the system operates efficiently and reliably. The flow direction of the pump changes smoothly, thanks to its well-engineered swashplate design that transitions seamlessly through the neutral position. Equipped with high-pressure relief valves that include an integrated boost function, the AA4VG90HD3DM1/32L-NSF52F021D-S offers enhanced safety and performance characteristics. Additionally, it comes standard with an adjustable pressure cutoff, allowing for precise control over the operational parameters of the hydraulic system. The model also includes a boost pressure relief valve which further contributes to its robust safety features. Its through-drive capability is noteworthy; it can accommodate the mounting of additional pumps up to the same nominal size, providing versatility for complex hydraulic systems. This Bosch Rexroth variable pump is recognized for its extensive range of control options, catering to various application requirements. The swashplate design underpins its adaptability and efficiency in a wide array of operational contexts. With such advanced features and capabilities, this particular model is ideal for applications requiring precise hydraulic fluid control and reliable high-pressure operation.
