No. The pumping module is oil-free and does not require routine vacuum pump oil changes. Follow the model-specific Edwards manual for all maintenance.
Tip seals are a normal wear item in many scroll pumps. Reduced vacuum, slower pump-down or a reached service interval can indicate that inspection or replacement is due.
A tip-seal kit addresses normal scroll-tip wear. An overhaul may be appropriate when bearings, valves, seals or other internal components require service. Diagnosis should be based on pump condition and the Edwards service instructions.
