I have been very impressed with the Grundfos SQFlex pumps. I have installed several of them over the last 6 or 7 years, and I haven't seen any issues yet. I've had way better success with them than with the sun pumps for wells. They are extremely versatile, efficient, and seemingly fantastic quality.
I've heard great things about the Lorentz pumps, but I haven't used them so I can't offer any comparisons. I get an awesome price for Grundfos from my regional distributor which is Delco Western. I've looked into a few other wholesale places, and they can't seem to touch Delco Western's prices. If you want more info on the Grundfos, you can contact me off-list, and I'll give you my pricing and any info you may want. Thanks, Kienan ________________________________ From: RE-wrenches <re-wrenches-boun...@lists.re-wrenches.org> on behalf of John Blittersdorf <john.blittersd...@gmail.com> Sent: Wednesday, February 28, 2018 5:09 PM To: RE-wrenches Subject: Re: [RE-wrenches] Lorentz pumps Jay, I have one on my own well 480’ down a 800’ deep well. At the time, they could only handle 500’ but since then have one that can pump from 1000’ and more. I only sold a few. I did have to replace the circuit board on the controller a couple of years ago and delt with a Lorentz dealer which seems to be the major one located in Texas. Overall, I have been impressed with the pump. It turns 17 Year’s old this year and started out as a direct solar pump with 4 100 watt panels but I later connected it to a 48 volt system when a cabin was built near the wellhead.

I know they have sort of come and gone from the USA. Is anyone using them, have any pros/cons vs Grundfos and where to get them? thanks jay peltz power _______________________________________________ List sponsored by Redwood Alliance List Address: RE-wrenches@lists.re-wrenches.org<mailto:RE-wrenches@lists.re-wrenches.org> Change listserver email address & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://www.mail-archive.com/re-wrenches@lists.re-wrenches.org/maillist.html List rules & etiquette: www.re-wrenches.org/etiquette.htm<http://www.re-wrenches.org/etiquette.htm> Check out or update participant bios: www.members.re-wrenches.org<http://www.members.re-wrenches.org>
