The Bosch Rexroth AA4VG71HD3D1/32L-NSF52F001D (R902205912) is a high-pressure axial piston pump designed for closed circuit applications. It features an integrated boost pump that provides both boost and pilot oil supply, ensuring consistent performance and reliability. The swashplate design allows for smooth changes in flow direction as it moves through the neutral position, which is crucial for precise control in hydraulic systems. This model includes high-pressure relief valves that come with an integrated boost function and an adjustable pressure cutoff as a standard feature, offering enhanced safety and efficiency. Additionally, the boost pressure relief valve contributes to the overall stability of the system by managing fluctuations in pressure. The AA4VG71HD3D1/32L-NSF52F001D pump is capable of handling a nominal pressure of up to bar and can withstand a maximum pressure of bar, making it suitable for demanding applications that require robust performance under high-pressure conditions. Its SAE version is tailored specifically for the US market, adhering to local standards and specifications. Furthermore, this Bosch Rexroth pump comes with a through-drive option which allows for the mounting of additional pumps up to the same nominal size directly onto it, facilitating compact system design and simplifying installation processes. A wide range of control options are available to customize the pump's operation according to specific application requirements. Designed with durability in mind, this axial piston pump is built to offer reliable service in various applications while maintaining efficiency and precision within closed hydraulic circuits. Its advanced features make it a versatile component suitable for integration into complex hydraulic systems where performance and control are paramount.
