FAQ;

Q1: What are the normal operating parameters for the A10VSO series?

• Oil temperature: 40–60°C (max 80°C; temperatures above 80°C accelerate oil oxidation and seal degradation).
• Suction pressure: -0.8 to -0.2 bar (avoid negative pressure below -0.8 bar, which causes cavitation).
• Discharge pressure: ≤ 280 bar (rated) or ≤ 350 bar (peak, < 10% of operating time).
• Vibration: ≤ 4.5 mm/s (measured at the pump housing; excessive vibration indicates misalignment or bearing wear).

Q2: How often should I perform maintenance on the A10VSO pump?

Q3: How to store the A10VSO pump if it is not used for a long time?

1. Clean the pump: Flush the internal oil passages with clean hydraulic oil to remove contaminants.
2. Seal ports: Plug the suction and discharge ports with plastic caps to prevent dust/water ingress.
3. Store in a dry environment: Keep the pump in a room with temperature 5–30°C and relative humidity < 60% (avoid direct sunlight or dampness).
4. Rotate the shaft: Manually rotate the pump shaft 1–2 times every 3 months to prevent bearing rust.
