Power is getting out of the pumping biz, and we’re the only Monoflo
distributor in the US. Our experience with Monoflo hasn’t been good.
We’ve seen a number of pump failures recently, support from the
manufacturer is pretty thin, and troubleshooting in the field is poorly
developed and documented. Basically it’s… pump not
working? Try plugging in a new controller. Still not working? Plug in a
new pump. Dealers don’t keep expensive pumps on the shelf in case
of breakdowns, so repairs usually end up taking weeks. Not good for
dealer/customer relations!<o:p></o:p></span></p>

rapidly-expanding grid-tie market that our tech support crew is getting loved

pumping projects challenging and interesting, but the tech cloning project has
hit some snags.<o:p></o:p></span></p>

<p class=MsoNormal>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?<o:p></o:p></p>

set up the PV arrays for six Grundfos SQ Flex submersible well pumps on a
