The Bosch Rexroth AA4VG90HD3DMT1/32L-NSF52F041D (R902249846) is a high-pressure axial piston pump designed for closed circuit applications. This model features an integrated boost pump that ensures the smooth supply of boost and pilot oil, which is critical for the proper functioning of hydraulic systems. The pump's flow direction can change seamlessly when the swashplate is adjusted through the neutral position, allowing for flexible control of hydraulic fluid flow. Equipped with high-pressure relief valves that include an integrated boost function, this Bosch Rexroth pump provides reliable performance under varying pressure conditions. The pressure relief valves also come with an adjustable pressure cutoff as a standard feature, enhancing safety and efficiency within hydraulic operations. One of the key capabilities of this pump is its boost pressure relief valve, which helps to manage system pressures and maintain stable operations. Additionally, it offers a through drive option that allows for the mounting of additional pumps up to the same nominal size, facilitating system expansion or customization without requiring extensive modifications. The AA4VG90HD3DMT1/32L-NSF52F041D is built with a swashplate design that supports high endurance and optimized fluid dynamics. It has been engineered to meet stringent requirements in terms of nominal and maximum pressures, making it suitable for demanding applications that require robust performance. This particular model is tailored for the US market with its SAE version configuration, ensuring compatibility with standard American equipment and systems. Its design reflects Bosch Rexroth's commitment to engineering excellence and reliability in hydraulic components, making it a valuable asset in various applications requiring precise control over high-pressure fluid dynamics in closed circuit systems.
