The Bosch Rexroth AA4VG125EP4D1/32R-NSF52F691DH (R902205646) is a high-pressure axial piston pump designed for closed-circuit applications. This particular model features an integrated boost pump, which ensures both boost and pilot oil supply, enhancing the efficiency and reliability of the hydraulic system it serves. The flow direction within this pump transitions smoothly as the swashplate moves through the neutral position, which is critical for precise control in various applications. This pump is equipped with high-pressure relief valves that incorporate a boost function, offering an additional layer of protection against pressure spikes. It comes standard with an adjustable pressure cutoff, providing customization to meet specific application requirements. Additionally, the boost pressure relief valve contributes to the overall safety and performance of the pump. A notable feature of this model is its through-drive capability, which allows for the mounting of additional pumps up to the same nominal size. This flexibility makes it suitable for complex hydraulic systems requiring multiple pumps in tandem. The variety of controls available with this pump ensures adaptability to a broad range of operational conditions. Constructed with a robust swashplate design, the AA4VG125EP4D1/32R-NSF52F691DH can handle a nominal pressure of up to 400 bar and peaks at 450 bar, demonstrating its capability to operate under high-pressure demands. This SAE version has been tailored specifically for the US market, ensuring compliance with local standards and regulations. In summary, this Bosch Rexroth axial piston pump stands out for its integrated features that support smooth operation and versatility in closed-circuit applications while maintaining safety through its advanced relief valve system and customizable pressure settings.
