The Bosch Rexroth PLAA4CSG 250 EPD (R902480449) is a high-efficiency, swashplate design pump engineered for closed circuit applications. This robust high-pressure pump is notable for its integrated boost pump which supplies both boost and pilot oil, ensuring reliable performance and longevity. The inclusion of integrated pressure relief valves for boost, control, and high-pressure circuits contributes to the safety and functionality of the system. Its durable construction promises a very long service life, making it an ideal choice for demanding operations. The PLAA4CSG 250 EPD pump features an integrated flushing valve that aids in maintaining the optimal condition of the hydraulic fluid, thus prolonging the system's lifespan. The ability to change flow direction smoothly as the swashplate moves through the neutral position is a testament to its sophisticated design, which also allows for axial and radial load capacity of the drive shaft. This model stands out due to its low operating noise levels and visual swivel angle indicator that enhances user control and monitoring capabilities. With short control response times, operators can expect precise performance in various applications. Moreover, its high total efficiency marks it as an energy-conscious choice without sacrificing power. Designed with a through-drive option, this pump facilitates the mounting of additional pumps up to the same nominal size directly onto it, streamlining system complexity and saving space. Its metric version adheres to international standards and specifications with a nominal pressure rating of bar and a maximum pressure bar capability suitable for rigorous use in closed hydraulic circuits.
