Section VII - Troubleshooting
General Notes:
•
Do not pump liquids containing ferrous metal fines.
•
If magnets decouple, stop pump immediately. Operating the
pump with the magnets decoupled will eventually weaken
•
the magnets.
•
Power monitors are required and must be used with all ATEX
certified pumps.
•
Do not use mismatched drive magnet assemblies (different
number of magnets on inner and outer drive magnet
assemblies).
•
