Product Description
The Rexroth A10VSO140 is a high-performance variable displacement axial piston pump designed for demanding industrial hydraulic appliions. This German-engineered pump offers reliable operation and precise control in open-circuit systems.
Troubleshooting Guide
- Insufficient or no oil output: Check for clogged filters, low oil level, or internal leakage. Adjust the variable piston or replace worn components.
- Vibration and noise: Verify pump-motor alignment, check bearings, and ensure proper oil viscosity and pipe sizing.
- Overheating: Inspect mechanical clearances, check for excessive back pressure, and maintain proper cooling.
- Oil leakage: Examine spindle oil seals, internal leakage points, and external pipe connections.
Maintenance Requirements
- Maintain oil temperature between 25-60°C with cleanliness level ≥ 8
- Conduct comprehensive inspections every 6 months
- Check oil replenishment pump status after 3000 hours of operation
- Always prime pump before starting to prevent dry friction
Installation Requirements
- Pump-motor shaft concentricity must be < 0.05mm
- Maximum suction height should not exceed 500mm
- Use original manufacturer seals and wear components for optimal performance

Frequently Asked Questions
What is the A10VSO140 pump used for?
This variable displacement axial piston pump is designed for open-circuit hydraulic systems in industrial and mobile appliions including mining equipment, construction machinery, and marine deck machinery.
What are the key technical specifiions?
Rated pressure: 280 bar (28 MPa), Peak pressure: 350 bar (35 MPa), Displacement: 140 cm³/rev, with flow control proportional to drive speed and adjustable via swashplate angle.
How to troubleshoot low flow or no output?
Check for insufficient suction (clogged filters/low oil level), internal leakage from worn seals, incorrect swashplate angle, or motor rotation direction.
What maintenance is required?
Regularly check oil cleanliness, ensure proper pump-motor alignment, and monitor for overheating caused by mechanical friction or high system pressure.
