Frequently Asked Questions

What are the fluid cleanliness requirements?

To ensure reliable operation and long service life, the oil cleanliness should be at least NAS 1638 Class 9 or ISO/DIS 4406 18/15.

Why does my pump get overheated?

Common causes for excessive heating include:

Internal Leakage: Excessive internal leakage within the pump components converts hydraulic energy to heat.
Mechanical Friction: Dry or semi-dry friction due to worn parts or inadequate lubrication generates heat.
Fluid Friction: Inadequate tank capacity or cooling, causing the system to overheat.
Clogged Return Line Filter: A blocked return filter creates high backpressure, leading to increased temperature.
Low Oil Level: Insufficient oil in the reservoir reduces cooling capacity.

What does daily/regular maintenance involve?

Keep the pump exterior clean from dust and oil.
Check oil levels before start-up and during operation.
Listen for abnormal noises during operation, which may indicate internal issues like part wear or looseness.
