Circ pump altternative

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 <img src= :" title="Question" /> :" title="Question" />

Does the Grundfos have a magnetic drive?

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.
