The Bosch Rexroth A4VG56DA1D3L/32R-NZC02F023SQ-S (R902232753) is a high-pressure pump designed for closed-circuit applications. It features an integrated boost pump which serves the dual purpose of providing boost and pilot oil supply, ensuring the system operates efficiently even under demanding conditions. The flow direction within this pump changes smoothly as the swashplate moves through its neutral position, which enhances the operational precision and responsiveness of the hydraulic system. This model comes equipped with high-pressure relief valves that include an integrated boost function, contributing to the pump's ability to manage pressure spikes effectively. The presence of an adjustable pressure cutoff as a standard feature allows for precise control over maximum system pressure, thereby protecting both the pump and connected components from potential overpressure damage. Furthermore, it includes a boost pressure relief valve and offers a through-drive option, enabling the mounting of additional pumps up to the same nominal size. This flexibility allows for system expansion or customization according to specific application needs without requiring significant redesigns or additional space. The swashplate design is central to this model's functionality, providing reliable and consistent performance in various hydraulic applications. The Bosch Rexroth A4VG56DA1D3L/32R-NZC02F023SQ-S is built for durability and is capable of operating at a nominal pressure of up to bar with a maximum pressure limit of bar. Its metric version ensures compatibility with standardized systems worldwide, making it a versatile choice for global applications requiring robust hydraulic solutions.
