The Bosch Rexroth AA4VG71DWD1/32L-NSF52F021D-S (R902249630) is a state-of-the-art high-pressure pump designed for closed circuit applications. This model, tailored specifically for the US market with its SAE version, is engineered to deliver reliable performance and durability. The integrated boost pump ensures both boost and pilot oil supply are adequately maintained, enhancing the pump's efficiency and responsiveness. The flow direction of this pump transitions smoothly as the swashplate moves through its neutral position, allowing for precise control of fluid movement within hydraulic systems. This particular model features high-pressure relief valves that come with an integrated boost function, ensuring the system is protected from pressure spikes while maintaining optimal operation. Additionally, it is equipped with an adjustable pressure cutoff as a standard feature, providing an extra layer of security against over-pressurization. The boost pressure relief valve incorporated into the design further contributes to the pump's robust safety mechanisms. The AA4VG71DWD1/32L-NSF52F021D-S offers flexibility in application thanks to its through-drive capability, which allows for the mounting of additional pumps up to the same nominal size directly onto it. This feature makes it an ideal choice for systems requiring multiple pumps working in tandem. With its swashplate design, this Bosch Rexroth pump achieves a balance between high performance and energy efficiency. It operates effectively within a nominal pressure range (bar) and can withstand maximum pressure (bar) peaks that are typical in demanding hydraulic systems. Its size and build quality make it suitable for various applications where consistent hydraulic power is critical. The Bosch Rexroth AA4VG71DWD1/32L-NSF52F021D-S demonstrates exceptional capabilities as a high-pressure pump in closed circuits, embodying precision engineering for advanced hydraulic solutions.
