The Bosch Rexroth AA4VG180HD3DM1/32L-NSD52F021D (R902129855) is a high-pressure axial piston pump designed for applications in closed circuits. Its integrated boost pump ensures efficient boost and pilot oil supply, making it a reliable component for various hydraulic systems. The pump's design allows for smooth flow direction changes as the swashplate moves through the neutral position, enhancing the operational smoothness and control of the machinery it is installed in. This model features high-pressure relief valves that come with an integrated boost function, ensuring safety and performance under high-pressure conditions. Additionally, it includes an adjustable pressure cutoff as a standard feature, providing added protection against system overloads. The boost pressure relief valve further contributes to its robust safety mechanisms. The AA4VG180HD3DM1/32L-NSD52F021D is capable of handling a nominal pressure of up to 450 bar and can withstand a maximum pressure of 530 bar. This capability makes it suitable for heavy-duty applications requiring consistent and reliable hydraulic power. The through-drive feature allows for the mounting of additional pumps up to the same nominal size, offering versatility in configuring multi-pump systems. Designed with a swashplate mechanism, this pump is engineered to deliver precise performance in demanding environments. It comes in an SAE version tailored specifically for the US market, adhering to industry standards and requirements. Overall, the Bosch Rexroth AA4VG180HD3DM1/32L-NSD52F021D hydraulic pump stands out with its high-pressure capabilities, integrated safety features, and flexible configuration options, making it an essential component for various hydraulic applications requiring closed circuit operations.
