The Bosch Rexroth AA4VG71HWD1/32R-NSF52F021S (R902249847) is a high-pressure axial piston variable pump designed for applications in closed circuits. This particular model is optimized for the SAE version tailored to the US market, focusing on delivering reliable and efficient performance under demanding conditions. The pump features an integrated boost pump that ensures consistent boost and pilot oil supply, enhancing its operational capabilities. Its design allows for smooth flow direction changes as the swashplate transitions through the neutral position, ensuring precise control for users. Equipped with high-pressure relief valves that incorporate a boost function, this model guarantees safety and durability by managing pressure spikes effectively. The adjustable pressure cutoff comes as a standard feature, providing additional control over the operation of the pump to suit various application needs. Additionally, the boost pressure relief valve is an integral part of its design, contributing to its robust performance. This unit offers versatility through its through-drive capability, which permits the mounting of additional pumps up to the same nominal size directly onto it without requiring extra space or complex configurations. This feature simplifies system design and can lead to cost savings in terms of both space and equipment. The swashplate design of this Bosch Rexroth pump is well-suited for high-pressure applications within closed circuits, making it an ideal choice for a wide range of hydraulic functions where consistent and reliable fluid power is necessary. With nominal pressure ratings at bar levels and maximum pressure capacities reaching higher bar thresholds, this pump is engineered to meet stringent demands while maintaining efficiency and longevity in service.
