The Bosch Rexroth AA4VG56EP4DMT1/32R-NSC52F003PP (R902249872) is a high-pressure pump designed for closed-circuit applications. This particular model features an integrated boost pump that serves the dual purpose of providing boost and pilot oil supply, ensuring the system operates efficiently even at lower speeds. The flow direction within this pump transitions smoothly as the swashplate moves through its neutral position, which is critical for maintaining consistent hydraulic performance and control. This axial piston variable pump comes with high-pressure relief valves that include an integrated boost function, enhancing the safety and reliability of the operation by preventing overpressure conditions. Additionally, it is equipped with an adjustable pressure cutoff as a standard feature, allowing for precise control over the maximum pressure limit within the hydraulic system. Further adding to its versatility, the AA4VG56EP4DMT1/32R-NSC52F003PP includes a boost pressure relief valve and offers a through-drive capability. This means it can be used in tandem with additional pumps up to the same nominal size, making it suitable for complex hydraulic systems requiring multiple pumps. The pump is constructed using a swashplate design and is engineered to withstand nominal pressures of up to 280 bar with peak pressures reaching up to 350 bar. It is tailored specifically for the US market with its SAE version compatibility, ensuring seamless integration into a wide range of equipment conforming to North American standards. Overall, this Bosch Rexroth axial piston variable pump stands out due to its robust construction, advanced control features, and flexible configuration options. Its capabilities make it well-suited for mobile and industrial applications where precise hydraulic control and reliable high-pressure performance are essential.
