Like an engineer
I am having another exercise with the well from Hell. My third Lorentz is dead. It sits at 550' (650' to bottom).
Supplier thought it was the controller. I bought another controller - no. So I need another new pump. I have been without water for about 1.5 month. The water is free of sand or other junk. Not corrosive.
While working with a vendor for the problem, they suggested a Grundfos 6SQF-3 instead of another Lorentz. Either would provide acceptable flow. Including the pump still in the well, I now have 3 dead Lorentz pumps from about 15 total years of use.
My question. Which pump is the most reliable and long lived. Other possibilities would also be considered. I favor the Archimedes pump approach. Less power consumed. Should last a long time.
I looked at the documentation of the Grundfos. It has a huge amount of parts in the pump. Lorentz, not so much. I have seen some comments about problems with Grundfos in some versions.
I am hoping there are people out there that can share results with the pumps.
