FAQ:

1. 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.

5. What are common applications?

• Excavator power steering systems.

• Industrial hydraulic presses.

• Mobile machinery requiring variable flow/pressure.

6. How to troubleshoot leaks or performance issues?

• Leaks: Check seals, valve plate, or cylinder block wear.

• Low Pressure: Inspect control settings (DFR/DFLR valves) or piston wear.

• Noise: Air ingress or cavitation; verify fluid viscosity and inlet conditions.

7. Where can I find spare parts?

OEM-equivalent parts (e.g., R902429793 for A10VSO140DFLR valves) are available through authorized distributors.

8. What maintenance is required?

• Regular oil changes (ISO VG 46-68 recommended).

• Monitor contamination levels (target ISO 18/15/12 cleanliness).

• Inspect seals and bearings annually.

9. Is the A10VSO140 interchangeable with other models?

It shares some parts with the A10VO series but verify compatibility (e.g., shaft size, porting) before substitution.

10. How to order or get support?

Contact suppliers with the full model number (e.g., A10VSO140DFLR/31R-PPB12N00) for pricing and lead times.
