German original axial piston pump designed for hydrostatic transmission in open circuits. The A10VSO series offers stepless flow regulation through swashplate angle adjustment, making it ideal for high-power hydraulic systems in industrial and mobile appliions.
Troubleshooting Guide
Insufficient/no oil output: Check oil filter, pump internal leakage, or motor phase sequence
Vibration/noise: Inspect shaft alignment, bearing condition, and oil viscosity
Overheating: Verify mechanical clearances and cooling system efficiency
Oil leakage: Examine shaft seals and pipeline 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
