A10VSO140DRG/32L-PPB22U99 A10VSO140DG/32L-VPB22U99 A10VSO140DG/32L-PPB32U00 Rexroth Germany imported mechanical hydraulic pump

The Rexroth A10VSO is a high-performance axial variable displacement piston pump designed for industrial and mobile hydraulic systems. As a flagship product in Rexroth's hydraulic portfolio, it stands out for its pressure-compensated displacement control, which automatically adjusts output flow based on system pressure demands. This design delivers exceptional energy efficiency, precise flow regulation, and robust reliability—making it suitable for applications requiring consistent performance under dynamic load conditions. Unlike fixed-displacement pumps, the A10VSO optimizes power consumption by only supplying the flow needed, reducing heat generation and operational costs.

Each segment of the A10VSO model code encodes critical technical specifications, enabling quick identification of pump configuration. Taking A10VSO140DR/31R-PPB12N00 as an example, the breakdown is as follows:

• A10VSO: Product series identifier - axial variable displacement piston pump with swashplate design
• 140: Nominal displacement - 140 cm³/rev (cubic centimeters per revolution), indicating the maximum volume of fluid delivered per rotation
• DR: Control device type - "D" for pressure compensator, "R" for remote control capability (combined control mode)
• 31: Design variant - 31st design iteration, denoting specific internal component configurations and pressure ratings
• R: Rotation direction - clockwise rotation when viewed from the drive shaft end (L = counterclockwise)
• PPB12: Additional features - "PP" for pressure relief valve integration, "B12" for standard seal material and port thread type
• N00: Special design code - no special modifications (custom codes indicate tailored features like high-temperature seals)
