The A10VSO140 is a variable displacement axial piston pump designed for open-circuit hydraulic systems in industrial and mobile appliions including mining equipment, construction machinery, marine deck machinery, and concrete pump trucks.
2. Key technical specifiions
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. Common control types
The pump supports multiple control options:
DR: Pressure control
DFR: Pressure/flow control
DFLR: Pressure/flow/power control
ED: Electrohydraulic pressure control
4. Troubleshooting 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. Maintenance requirements
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. Closed-loop system compatibility
No, the A10VSO140 is designed exclusively for open-loop circuits. For closed-loop systems, consider pumps like the A4VSO series.
