If everything seems ok, then clean off the old grease and use something like that white grease, lubriplate i believe. It turns so slow almost any grease would work. ie, better than no grease at all.
But, the brushes on the electric motors could be shot too. Or the bearings on the motor. Does it dose every day? for 5 years?
So hard to say, long distance and all

Thanks for your insight, by the way. Sounds like you know a thing or two about peristaltic pumps! Where would you get lubriplate?
One pump was used for top-off so it was every day for at least 2 to 3 years. The other was barely used at all, just for dosing calcium once a day for about 3 years. Oh, come to think of it, that pump was also used to pump water into my denitrator (or out of it, I can't remember!)
