Got an old Hot Springs, tired of replacing the circ pump every 18 months,
is there a safe alternative reliable pump that is direct drive instead of the magnet drive??
Whats the point of the magnet drive?
I dont get it, I have 10 HP circ pumps in my bldg that run 24/7 for 20-25 years with zero problems, and this stupid $160
1/10 HP pump lasts about 18 months and gets noisey and lockes up.
No amount of taking it apart and cleaning will help.

Magnet drives eliminate a "shaft seal". The ball and socket impeller is scaring due to scale, dry run, or precipitants in the water. Grundfos if it will retro. Any one else

No,
Armature drive within a stainless water cooling jacket.

Is it a shaft drive, like normal water pumps?

Yes, but the pump is not repairable once the shaft seal begins leaking.
