The Bosch Rexroth AA4VG125EP4D1/32L-NSF52K041EH (R902249586) is a high-pressure pump designed for use in closed circuit applications. This particular model is tailored to the SAE standards prevalent in the US market, ensuring compliance and ease of integration for domestic users. The pump features an integrated boost pump which serves the dual purpose of providing boost and pilot oil supply, enhancing its operational efficiency. Its design allows for smooth flow direction changes as the swashplate moves through the neutral position, ensuring seamless operation. This model comes equipped with high-pressure relief valves that incorporate a boost function, offering additional safety and reliability. The pressure cutoff is adjustable by default, allowing users to set the desired maximum pressure according to their specific needs. Additionally, a boost pressure relief valve is included to further safeguard against overpressure conditions. For versatility in system design and expansion, this pump offers a through drive option. This feature enables the mounting of additional pumps up to the same nominal size directly onto the AA4VG125EP4D1/32L-NSF52K041EH without requiring extra space or complex configurations. The swashplate design of this Bosch Rexroth pump underscores its robust construction and suitability for demanding applications that require precise control and durability. With its size optimized for performance within its nominal pressure bar rating and capable of withstanding maximum pressure bar levels, this pump represents a reliable solution for hydraulic systems in need of consistent high-pressure performance.
