FAQ:

What is the A10VSO140 pump?

The A10VSO140 is an axial piston variable displacement pump from the Rexroth A10VSO series, designed for open-loop hydraulic circuits. It is widely used in industrial and mobile applications (e.g., excavators, construction machinery) due to its high-pressure capacity and robust performance.

2. What are the key specifications?

• Displacement: 140 cc/rev (model-specific).

• Control Types: DR, DFR, DRG, DFR1, DFLR (for flow/pressure regulation).

• Pressure Rating: High-pressure operation (exact PSI/bar values depend on configuration).

• Shaft Rotation: Typically clockwise (CW) or counterclockwise (CCW), depending on the model.

3. What are the compatible parts and components?

Common replaceable parts include:

• Cylinder block (barrel)

• Piston assembly

• Valve plate

• Swash plate

• Drive shaft

• Thrust plate.

4. How to identify the model number?

Example model: A10VSO140DFLR/31R-PPB12N00

• A10VSO140: Series and displacement.

• DFLR: Control type (e.g., DFLR for pressure limiting and load sensing).

• 31R: Porting configuration.

• PPB12N00: Additional design codes.
