They have motors with the same AC/DC voltage specs as the SQFlex pumps, but they also have a control panel where you can adjust the motor speed. These pumps do have higher water flow-rate specs, but maybe you could adjust it down enough to get the 3-4 gpm rate. According to the pump chart, the CRFlex model 1-17 will pump about 4 gpm at 328 ft of head with about 750W of power. Unfortunately, I don’t have enough experience with these pumps to know for sure about the ability or limitations of adjusting the motor speed, but I am looking for a Guinea Pig. (If any of you fine Wrenches out there have any experience with adjusting the CRFlex motor speed, please contact me off-list) </span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d"> </span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">Jay - contact me off-list if want to discuss using one of these pumps.</span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d"> </span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">Brian Teitelbaum</span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">AEE Solar</span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d"> </span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d"> </span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d"> </span></p><div><div style="border:none;border-top:solid #b5c4df 1.0pt;padding:3.0pt 0in 0in 0in"><p class="MsoNormal"><b><span style="font-size:10.0pt;font-family:"Tahoma","sans-serif";color:windowtext">From:</span></b><span style="font-size:10.0pt;font-family:"Tahoma","sans-serif";color:windowtext"> RE-wrenches [mailto:<a href="mailto:re-wrenches-bounces@lists.re-wrenches.org">re-wrenches-bounces@lists.re-wrenches.org</a>] <b>On Behalf Of </b>Jay<br><b>Sent:</b> Tuesday, August 02, 2016 9:44 AM<br><b>To:</b> RE-wrenches<br><b>Subject:</b> [RE-wrenches] Pump ideas</span></p></div></div><p class="MsoNormal"> </p><blockquote style="margin-top:5.0pt;margin-bottom:5.0pt"><div><p class="MsoNormal">Hi all</p></div></blockquote><p class="MsoNormal"><span style="color:windowtext"> </span></p><div><p class="MsoNormal"><span style="color:windowtext">I've got a pump choice question</span></p></div><div><p class="MsoNormal"><span style="color:windowtext"> </span></p></div><div><p class="MsoNormal"><span style="color:windowtext">140psi lift</span></p></div><div><p class="MsoNormal"><span style="color:windowtext">3-4gpm max</span></p></div><div><p class="MsoNormal"><span style="color:windowtext">12' suction out of shallow well</span></p></div><div><p class="MsoNormal"><span style="color:windowtext">2' water depth in well</span></p></div><div><p class="MsoNormal"><span style="color:windowtext">2' diameter well</span></p></div><div><p class="MsoNormal"><span style="color:windowtext">Slight sediment, clay mostly. </span></p></div><div><p class="MsoNormal"><span style="color:windowtext"> </span></p></div><div><p class="MsoNormal"><span style="color:windowtext">120/240vac power </span></p></div><div><p class="MsoNormal"><span style="color:windowtext"> </span></p></div><div><p class="MsoNormal"><span style="color:windowtext">Submersible won't work, too shallow</span></p></div><div><p class="MsoNormal"><span style="color:windowtext">Slow pump I'm concerned about filter changes</span></p></div><div><p class="MsoNormal"><span style="color:windowtext">Surface pump makes most sense. </span></p></div><div><p class="MsoNormal"><span style="color:windowtext"> </span></p></div><div><p class="MsoNormal"><span style="color:windowtext">Any recommendations? </span></p></div><div><p class="MsoNormal"><span style="color:windowtext"> </span></p></div><div><p class="MsoNormal"><span style="color:windowtext">Thanks </span></p></div><div><p class="MsoNormal"><span style="color:windowtext"> </span></p></div><div><p class="MsoNormal"><span style="color:windowtext">Jay</span></p></div><div><p class="MsoNormal"><span style="color:windowtext"> </span></p></div><div><p class="MsoNormal"><span style="color:windowtext"> </span></p></div><div><p class="MsoNormal"><span style="color:windowtext"> </span></p></div></div></body></html>
