Lubrications for a mag drive

[riche]

I have a mag 18 that was sitting dry for awhile, it needs to get something to get it going. I can get it to spin for a few seconds and they it stops and I took the magnet out and it seems like it’s dry

What is safe to put on it?

 

[shwareefer]

Nothing. Run it in a bucket of vinegar and RO water for a day.

Citric acid is your best bet. The magnets sometimes get old and rust and swell. You may need a new impellar.

And if that's the case, you're way better off buying a $75 Chinese DC pump than a $50 impellar. All the mag pumps are terribly innefficient
