The Bosch Rexroth AA4VG125EP4D1/32R-NSF52F071DP (R902275581) is a highly efficient axial piston variable pump designed for hydrostatic transmissions in closed circuits. This advanced pump features an integrated boost pump which ensures boost and pilot oil supply, contributing to its reliable performance and efficiency. The flow direction within the pump changes smoothly, thanks to the meticulously engineered swashplate that moves seamlessly through the neutral position. Enhanced operational safety and performance are guaranteed with the inclusion of high-pressure relief valves that come with an integrated boost function. Furthermore, this model is equipped with an adjustable pressure cutoff as standard, offering additional control and customization based on specific application requirements. The boost pressure relief valve serves as a protective mechanism, ensuring the system operates within safe pressure limits. A key feature of the AA4VG125EP4D1/32R-NSF52F071DP is its capability for through drive installations, allowing for the mounting of further pumps up to the same nominal size directly onto it – a design that enables space-saving and cost-effective hydraulic systems. The versatility of this pump is also evident in its wide range of control options, catering to various application needs and ensuring precise operation. Built on the robust swashplate design principle, this Bosch Rexroth variable pump is recognized for its durability and reliability in demanding environments. Its design characteristics make it suitable for high-end applications requiring precise hydraulic fluid control and power management.
