The Bosch Rexroth A4VG125EP4/32+A4VG56EP4/32+A10VO28DFR/31 (R902249508) is an advanced hydraulic pump designed for high-pressure applications within closed circuits. This pump showcases an integrated boost pump which serves to supply both boost and pilot oil, ensuring the system operates efficiently and reliably. The flow direction of the pump can be changed smoothly as the swashplate transitions through the neutral position, highlighting its precision control capabilities. This model boasts high-pressure relief valves that incorporate a boost function, offering additional safety and performance benefits. Furthermore, it comes standard with an adjustable pressure cutoff feature, allowing for customization according to specific application requirements. The inclusion of a boost pressure relief valve further enhances its operational security. The A4VG125EP4/32+A4VG56EP4/32+A10VO28DFR/31 is designed with a through-drive option which provides versatility in system design by permitting the mounting of additional pumps up to the same nominal size. This feature allows for a broader range of applications and can lead to more compact system designs by stacking multiple pumps together. In terms of control options, this model offers a large variety to suit various applications and user preferences. Its swashplate design is indicative of its robustness and aptitude for handling demanding tasks. When it comes to specifications, this Bosch Rexroth pump has a size that conforms to metric standards, with a nominal pressure bar rating suitable for most high-pressure needs and a maximum pressure bar rating that underscores its capacity to operate at peak levels in challenging conditions. Overall, the A4VG125EP4/32+A4VG56EP4/32+A10VO28DFR/31 is engineered for durability and performance in closed circuit systems where precise hydraulic power is essential. Its comprehensive design features make it well-suited for complex hydraulic tasks requiring reliable high-pressure operation.
