Rexroth A10VSO140 Variable Displacement Axial Piston Pump

The Rexroth A10VSO140 is a high-performance variable displacement axial piston pump designed for demanding industrial hydraulic applications. This German-engineered pump offers reliable operation and precise control in open-circuit systems.

• 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.

• 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

• 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
