The Bosch Rexroth AA4VG90EP4D1/32L-NSF52F001DP (R902232825) is a state-of-the-art high-pressure pump designed for closed circuit applications. This particular model features an integrated boost pump, which is essential for both boost and pilot oil supply, ensuring the system operates efficiently even under varying conditions. The flow direction of this pump can be changed smoothly as the swashplate moves through the neutral position, which enhances the operational flexibility of the device. This model comes with high-pressure relief valves that include an integrated boost function, providing additional safety and control over the system pressure. Moreover, it includes an adjustable pressure cutoff as a standard feature, allowing users to set maximum pressure limits to protect their hydraulic systems from potential overpressure damage. Another key feature of this Bosch Rexroth pump is its boost pressure relief valve, which further contributes to the overall safety and efficiency of the system. The pump also offers a through drive option, making it possible to mount additional pumps of up to the same nominal size directly onto it without requiring extra space or adapters. This modular capability makes it an ideal choice for systems that require multiple pumping solutions working in tandem. The AA4VG90EP4D1/32L-NSF52F001DP is designed with a swashplate mechanism that ensures reliable performance in demanding applications. With its nominal pressure bar and maximum pressure bar capabilities, this pump can handle rigorous use in various hydraulic systems. Additionally, it's configured in an SAE version specifically tailored for the US market, ensuring compatibility and ease of integration with a wide range of equipment and machinery used in North America. In summary, this Bosch Rexroth high-pressure pump is suited for demanding applications requiring robust performance and reliability in closed circuits. Its integrated features and versatile design make it an excellent choice for those seeking advanced hydraulic solutions.
