The Bosch Rexroth AA4VG90EP4DMT1/32L-NSF52F001DP (R902148509) is a state-of-the-art axial piston variable pump characterized by its advanced engineering and versatility in application. This pump features an integrated boost pump which ensures consistent boost and pilot oil supply, essential for the efficient operation of hydraulic systems. Its design allows for a smooth change in flow direction as the swashplate moves through the neutral position, providing precise control over the hydraulic functions. The high-pressure relief valves are designed with an integrated boost function, enhancing safety and performance. The inclusion of adjustable pressure cutoff as standard offers additional control over the operational parameters, ensuring that the system can be finely tuned to specific requirements. Additionally, this model comes equipped with a boost pressure relief valve, further contributing to its overall reliability and durability. One of the key benefits of this Bosch Rexroth pump is its through-drive capability, which allows for the mounting of additional pumps up to the same nominal size directly onto it. This feature enables users to expand their hydraulic systems without requiring additional space, making it ideal for applications where space is at a premium. Furthermore, the AA4VG90EP4DMT1/32L-NSF52F001DP offers a large variety of controls that cater to diverse operational needs. Its swashplate design is optimized for high efficiency and longevity under demanding conditions. With these capabilities, this axial piston variable pump represents a robust and flexible solution for various hydraulic applications requiring precise control and reliable performance over extended periods.
