4. How to troubleshoot low flow or no output?

Possible causes include:

• Insufficient suction due to clogged filters or low oil level.

• Internal leakage from worn seals or damaged valve plates.

• Incorrect swashplate angle or motor rotation direction.

5. What maintenance is required?

• Regularly check oil cleanliness to prevent contamination.

• Ensure proper alignment of pump and motor shafts to avoid vibration.

• Monitor for overheating caused by mechanical friction or high system pressure.

6. Can it be used in closed-loop systems?
