The Bosch Rexroth AA4VG56EP4D1/32L-NSC52F025DP (R902205568) is a high-pressure axial piston pump designed for closed circuit applications. This particular model boasts an integrated boost pump that serves the dual purpose of providing boost and pilot oil supply, ensuring the system operates efficiently and effectively. The pump is engineered to facilitate a smooth change in flow direction as the swashplate transitions through the neutral position, enhancing the operational control. Featuring high-pressure relief valves with an integrated boost function, this pump ensures safety and reliability under high-pressure conditions. It also comes with an adjustable pressure cutoff as a standard feature, allowing for customization based on specific application requirements. Additionally, it includes a boost pressure relief valve that contributes to the overall stability and performance of hydraulic systems. The AA4VG56EP4D1/32L-NSC52F025DP is capable of through-drive installations, which means it can be used in tandem with additional pumps up to the same nominal size, offering flexibility in system design. This model is specifically tailored for the US market with its SAE version compliance. Constructed using swashplate design principles known for their efficiency and durability, this Bosch Rexroth axial piston pump can handle nominal pressures of up to bar and maximum pressures of up to bar. Its robust design and versatile control options make it suitable for a wide range of demanding applications requiring precise control of fluid power in closed hydraulic circuits.
