have been supplying and installing the SQFlex series for about a decade. I'd
estimate something around 80-100 pumps out there, some PV direct filling
cisterns, some inverter powered directly pressurizing. </FONT></SPAN></DIV>

have had a couple failures of the dry run switch, in water sources that were
high in minerals (sensor gets all covered in scale). Had one of the very first
pumps installed motor failed a year ago, replaced with new and back it
goes down the hole. Just had first CU200 failure in queue to diagnose soon.

consider the SQFlex a very solid product. But the product does not have the
multi-decade field experience so hard to say how long will last.

would also like to hear service reports on this too, specifically the
standard grundfos centrifugal pumps with dc motor (SQF). helical rotors wear
faster, so of course their life would not be as long.<BR><BR>by comparison, i
have a 26 year old, 3/4 hp standard well pump which is still fully operational
and in irrigation season, pumps ~2500 gallons a day.</P>

How long do these stay in the hole before the need to be maintained or<BR>>
replaced? Do they last as well as standard AC deep well pumps?<BR>>
<BR>> <BR>> > I believe that the SQE has the constant-pressure
