The Bosch Rexroth P AA4CSG 250 EPD /30R-VSD85F994ME (R902492570) is a high-performance axial piston pump designed for demanding applications. This robust pump features an integrated boost pump, ensuring a reliable boost and pilot oil supply. It also comes equipped with integrated pressure relief valves for boost, control, and high-pressure circuits, enhancing the safety and reliability of the system it is integrated into. The pump has been engineered to offer a very long service life, which is a testament to its durability and the quality of its construction. One of the standout features of this model is its integrated flushing valve, which contributes to maintaining the optimal condition of hydraulic fluid and thus prolongs the system's overall lifespan. Additionally, it offers through-drive capability, allowing for the mounting of further pumps up to the same nominal size – this feature provides flexibility in system design. The P AA4CSG 250 EPD /30R-VSD85F994ME pump ensures smooth flow direction changes as the swashplate moves through its neutral position. The axial and radial load capacity of its drive shaft is designed to withstand significant stress, ensuring reliable operation under various conditions. Furthermore, it operates with low noise levels making it suitable for environments where noise reduction is essential. This particular model includes a visual swivel angle indicator for easy monitoring and boasts short control response times that contribute to efficient operations. With high total efficiency and a swashplate design optimized for closed circuit systems, this SAE version is tailored specifically for the US market. In terms of specifications, this unit has a sizeable displacement volume suited for heavy-duty applications. It can operate at a nominal pressure of bar while being capable of withstanding maximum pressure peaks up to bar – indicative of its strength in challenging operational scenarios.
