The Bosch Rexroth PL A4CSG 500 EPD /30L-VPH85F684DE (R902479881) is a high-performance axial piston pump designed for demanding hydraulic operations. This robust pump features an integrated boost pump, essential for both boost and pilot oil supply, ensuring consistent performance and reliability. It's equipped with integrated pressure relief valves that serve to protect the system from boost, control, and high-pressure scenarios. A key attribute of this model is its exceptionally long service life, which is a testament to its durable construction. The PL A4CSG 500 EPD /30L-VPH85F684DE also includes an integrated flushing valve which contributes to the maintenance of system efficiency and longevity. This feature allows for the continuous removal of contaminants and heat from the hydraulic fluid, thereby preserving the integrity of the system components. One of the standout capabilities of this pump is its through-drive functionality, which allows for the mounting of additional pumps up to the same nominal size directly onto it. This flexibility enables users to configure their hydraulic systems based on specific requirements without compromising on space or complexity. The flow direction within this unit transitions smoothly as the swashplate moves through its neutral position, enhancing operational control. Moreover, both axial and radial load capacities are supported by its drive shaft design. Users will appreciate the low operating noise level that contributes to a more pleasant working environment. Another practical feature is its visual swivel angle indicator that provides immediate feedback on pump settings. The short control response times facilitate quick adjustments and precise control over hydraulic functions. In terms of efficiency, this Bosch Rexroth pump offers high total efficiency due to its swashplate design—a crucial factor in reducing energy consumption and operational costs. The model adheres to metric measurement standards and is capable of handling a nominal pressure of up to bar with a maximum pressure threshold at bar in closed circuit applications.
