The Bosch Rexroth AA4VG125EP3D1/32L-NSF52F021DP (R902148238) is a highly efficient axial piston variable pump designed for hydrostatic drives in closed circuits. This particular model comes with an integrated boost pump, which ensures a reliable boost and pilot oil supply. The flow direction of the pump changes smoothly when the swashplate moves through the neutral position, highlighting its precision and control capabilities. It is equipped with high-pressure relief valves that have an integrated boost function, enhancing the safety and performance of the pump. Additionally, this model includes an adjustable pressure cutoff as a standard feature, allowing for customization according to specific application needs. The boost pressure relief valve further contributes to the operational safety and longevity of the system. A notable feature of this Bosch Rexroth pump is its through-drive capability, which permits the mounting of additional pumps up to the same nominal size, facilitating versatile configurations suitable for complex hydraulic systems. The AA4VG125EP3D1/32L-NSF52F021DP model employs a swashplate design that is well-suited for high-demand applications requiring variable volume flows and pressure regulation. The robust construction and engineering excellence of this pump ensure reliability in operation, making it ideal for high-end hydraulic applications where performance and durability are paramount.
