The Rexroth A10VSO140 series variable axial piston pump is a high-performance hydraulic pump designed for demanding applications in mining, construction, and industrial machinery. This German-engineered pump offers reliable operation with precise flow control.
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.
- 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
The pump supports multiple control options, including:
- DR: Pressure control
- DFR: Pressure/flow control
- DFLR: Pressure/flow/power control
- ED: Electrohydraulic pressure control
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
- 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
No, the A10VSO140 is designed exclusively for open-loop circuits. For closed-loop systems, consider pumps like the A4VSO series.
