[RE-wrenches] Grundfos

[Jason Szumlanski]

I'm interested to hear more about this. I am getting ready to pull the
trigger on a Lorentz PS200 well pump and controller (never used these
before). I did some research on the SQ Flex, and concluded the Lorentz
would be a good choice, despite the high price.

I have also installed several Grundfos SQ Flex submersible well pumps,
and had trouble with them, primarily with the control systems, the low
water shut off sensor has failed on several pumps, and the CU200 control
boxes have failed. The pumps themselves have held up so far, and seem to
be very efficient. I wish there were more solar direct well pump
options, I've tried the ETA pumps, the Sunpumps (which are great for low
head, low flow) and am about to try a Monoflow. Any other thoughts?

Wrenches,

 

I set up the PV arrays for six Grundfos SQ Flex submersible well pumps
on a cattle ranch. The first three have failed (in exact order of
installation) in about a year. Anyone else experiencing similar
problems? I had always heard great things about their equipment, is it
time to look elsewhere? Where?
