The A10VSO71 is a variable displacement axial piston pump with swashplate design, engineered for hydrostatic transmission in open circuits. This German-engineered plunger pump is ideal for loader motors and mining appliions, offering stepless flow regulation through swashplate angle adjustment.
Technical Support & Troubleshooting
Insufficient/no oil output: Check for clogged oil filter, low oil level, or air leakage in inlet pipe. Replace worn parts or adjust variable piston as needed.
Vibration/noise issues: Verify pump-motor alignment, check bearings, and ensure proper oil viscosity and pipe sizing.
Overheating: Adjust mechanical clearances, increase cooling capacity, or clean/replace filters.
Oil leakage: Inspect and replace spindle oil seals, check pipe connections and gaskets.
Maintenance Guidelines
Maintain oil temperature between 25-60°C with cleanliness level ≥ 8
Conduct comprehensive inspections every 6 months
Check oil replenishment pump status every 3000 operating hours
Always prime pump with oil before starting to prevent dry friction
Installation Requirements
Maintain pump-motor shaft concentricity < 0.05mm
Maximum suction height: 500mm
Use original seals and wear-resistant components for replacements
Ensure proper drain line routing with back pressure ≤ 0.5 bar
