The Bosch Rexroth AA4VG71NVDMT1/32R-NSF52F001D-S (R902190066) is a high-performance axial piston variable pump with a swashplate design engineered for hydrostatic drives in closed circuits. This state-of-the-art pump features an integrated boost pump that ensures consistent boost and pilot oil supply, which is crucial for the optimal operation of the hydraulic system. The flow direction of the pump can be changed smoothly and efficiently as the swashplate moves through the neutral position, which enhances the operational flexibility and control precision. Equipped with high-pressure relief valves that include an integrated boost function, this model guarantees safety and reliability by preventing overpressure conditions. Additionally, it comes with an adjustable pressure cutoff as a standard feature, providing users with enhanced control over their hydraulic systems' performance parameters. The AA4VG71NVDMT1/32R-NSF52F001D-S also includes a boost pressure relief valve to further safeguard against pressure spikes in the system. Moreover, its through-drive capability allows for the mounting of additional pumps up to the same nominal size directly onto it without requiring extra space or adapters, thus offering a compact and efficient solution for complex hydraulic systems. This Bosch Rexroth variable pump is designed to deliver high-quality performance and is suitable for various applications that require precise control of fluid flow and pressure. Its robust construction ensures durability and long service life even under demanding conditions. With its wide range of controls and configurations, this pump provides flexibility to match specific requirements of different hydraulic systems while maintaining efficiency and reliability.
