The Bosch Rexroth P AA4CSG 355 EPG /30R-VRD85F994N (R902557655) is a high-performance axial piston pump designed for demanding hydraulic operations. This robust high-pressure pump incorporates an integrated boost pump, which ensures a reliable boost and pilot oil supply. It also features integrated pressure relief valves for boost, control, and high-pressure circuits, providing enhanced safety and performance. The P AA4CSG 355 EPG /30R-VRD85F994N is engineered for a closed circuit application and is specifically configured in the SAE version for compatibility with the US market. Its swashplate design allows for smooth changes in flow direction as the swashplate moves through the neutral position. This contributes to the pump's exceptional control response times and overall efficiency. Built to withstand both axial and radial loads on its drive shaft, this model ensures durability and a very long service life. The low operating noise level of this pump makes it suitable for use in environments where noise reduction is important. Additionally, it includes an integrated flushing valve which aids in maintaining the hydraulic system's cleanliness and efficiency. The visual swivel angle indicator provides an immediate visual cue of the swashplate position, allowing for easy monitoring of pump operation. With its through-drive capability, it can accommodate further pumps up to the same nominal size, offering versatility in system design. Key specifications include its size designation (355), nominal pressure rating (bar), and maximum pressure capacity (bar), confirming its suitability for heavy-duty applications where reliable hydraulic power is critical. The total efficiency of this unit stands out in its class, making it a preferred choice for those seeking a high-quality hydraulic component that delivers consistent performance over time.
