FAQ:

What is the A10VSO140 pump used for?

The A10VSO140 is a variable displacement axial piston pump designed for open-circuit hydraulic systems. It is widely used in industrial and mobile applications such as mining equipment, construction machinery, marine deck machinery, and concrete pump trucks due to its high efficiency and adaptability.

2. 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.
