FAQ;

Q2: The pump makes abnormal noise (e.g., whistling, knocking). How to fix it?

Noise Type	Possible Cause	Solution
Whistling	Cavitation (air in the suction line)	Check for suction line leaks; ensure oil level is sufficient; clean the suction filter.
Knocking	Shaft misalignment or coupling damage	Realign the pump and motor shafts; replace the damaged coupling.
Grinding	Bearing wear or foreign debris in the pump	Disassemble the pump; replace worn bearings; flush internal passages to remove debris.
Vibrating noise	Loose mounting bolts or swashplate jamming	Tighten mounting bolts to the specified torque; inspect the swashplate for jamming (clean or replace if needed).

Q3: The pump’s oil temperature is abnormally high (above 80°C). What should I do?

Cause	Solution
Insufficient oil flow in the cooling system	Check the cooler fan/pump; clean the cooler’s heat exchanger (remove dirt buildup).
Hydraulic oil viscosity is too high	Replace with oil of the correct viscosity (15–40 mm²/s at 40°C).
Internal leakage (e.g., worn valve plate)	Overhaul the pump; replace the valve plate and piston seals.
System pressure is too high (overloaded)	Reduce the system load; check if the relief valve is stuck open.

6. Safety & Warranty

Q1: What safety precautions should be followed when working with the A10VSO pump?

Lockout/Tagout (LOTO): Before disassembling the pump, turn off the motor and relieve system pressure (open the relief valve) to avoid accidental startup or oil spray.
Pressure testing: Never exceed the pump’s peak pressure (350 bar) during testing; use a pressure gauge with a range ≥ 400 bar to monitor pressure.
Protective gear: Wear safety glasses, gloves, and oil-resistant boots when handling hydraulic oil (prevents skin irritation and eye injury).
No modifications: Do not modify the pump’s housing, swashplate, or control mechanism (voids the warranty and may cause catastrophic failure).
