FAQ:

What are the key technical specifications?

• Rated pressure: 280 bar (28 MPa)

• Peak pressure: 350 bar (35 MPa)

• Displacement: 140 cm³/rev

• Flow control: Proportional to drive speed and displacement, adjustable via swashplate angle.

3. What are the common control types?

The pump supports multiple control options, including:

• DR: Pressure control

• DFR: Pressure/flow control

• DFLR: Pressure/flow/power control

• ED: Electrohydraulic pressure control.

4. How to troubleshoot low flow or no output?

Possible causes include:

• Insufficient suction due to clogged filters or low oil level.

• Internal leakage from worn seals or damaged valve plates.

• Incorrect swashplate angle or motor rotation direction.

5. What maintenance is required?

• Regularly check oil cleanliness to prevent contamination.

• Ensure proper alignment of pump and motor shafts to avoid vibration.

• Monitor for overheating caused by mechanical friction or high system pressure.

6. Can it be used in closed-loop systems?

No, the A10VSO140 is designed exclusively for open-loop circuits. For closed-loop systems, consider pumps like the A4VSO series.

7. Where can I buy genuine A10VSO140 pumps?

Authorized distributors like Bosch Rexroth partners in China (e.g., Shenzhen Guanyu Hydraulic) offer original products with warranties.
