The Bosch Rexroth A4VG71DWDMT1/32R-NSF02F001D-S (R902205980) is a high-performance axial piston variable pump with a swashplate design, tailored for hydrostatic transmissions in closed circuits. This advanced pump features an integrated boost pump which ensures the supply of boost and pilot oil, essential for the efficient operation of hydraulic systems. The smooth flow direction transition as the swashplate moves through neutral is a testament to its sophisticated engineering, providing users with precise control over their hydraulic applications. Equipped with high-pressure relief valves that include an integrated boost function, this Bosch Rexroth pump maintains optimal performance by protecting the system from pressure spikes. The adjustable pressure cutoff comes as a standard feature, allowing for customization based on specific operational requirements. Additionally, it has a boost pressure relief valve to further enhance its safety features. Designed for versatility and expansion, the A4VG71DWDMT1/32R-NSF02F001D-S offers through-drive capability. This feature permits the mounting of additional pumps up to the same nominal size directly onto it, enabling complex hydraulic setups without needing extra space for separate pumps. Its wide range of controls provides flexibility for various application needs. With its robust design and advanced features, this Bosch Rexroth variable pump is well-suited for demanding applications that require reliable hydraulic power and precise control. Whether used in mobile or industrial settings, this pump delivers consistent performance and adaptability that professionals in various fields can rely on for their hydraulic system needs.
