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><o:p></o:p></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'> </span><o:p></o:p></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><o:p></o:p></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'> </span><o:p></o:p></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Brian Teitelbaum</span><o:p></o:p></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>AEE Solar</span><o:p></o:p></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'> </span><o:p></o:p></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'> </span><o:p></o:p></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'> </span><o:p></o:p></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"><u>re-wrenches-bounces@lists.re-wrenches.org</u></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><o:p></o:p></p></div></div><p class=MsoNormal> <o:p></o:p></p><blockquote style='margin-top:5.0pt;margin-bottom:5.0pt'><div><p class=MsoNormal>Hi all<o:p></o:p></p></div></blockquote><p class=MsoNormal><span style='color:windowtext'> </span><o:p></o:p></p><div><p class=MsoNormal><span style='color:windowtext'>I've got a pump choice question</span><o:p></o:p></p></div><div><p class=MsoNormal><span style='color:windowtext'> </span><o:p></o:p></p></div><div><p class=MsoNormal><span style='color:windowtext'>140psi lift</span><o:p></o:p></p></div><div><p class=MsoNormal><span style='color:windowtext'>3-4gpm max</span><o:p></o:p></p></div><div><p class=MsoNormal><span style='color:windowtext'>12' suction out of shallow well</span><o:p></o:p></p></div><div><p class=MsoNormal><span style='color:windowtext'>2' water depth in well</span><o:p></o:p></p></div><div><p class=MsoNormal><span style='color:windowtext'>2' diameter well</span><o:p></o:p></p></div><div><p class=MsoNormal><span style='color:windowtext'>Slight sediment, clay mostly. </span><o:p></o:p></p></div><div><p class=MsoNormal><span style='color:windowtext'> </span><o:p></o:p></p></div><div><p class=MsoNormal><span style='color:windowtext'>120/240vac power </span><o:p></o:p></p></div><div><p class=MsoNormal><span style='color:windowtext'> </span><o:p></o:p></p></div><div><p class=MsoNormal><span style='color:windowtext'>Submersible won't work, too shallow</span><o:p></o:p></p></div><div><p class=MsoNormal><span style='color:windowtext'>Slow pump I'm concerned about filter changes</span><o:p></o:p></p></div><div><p class=MsoNormal><span style='color:windowtext'>Surface pump makes most sense. </span><o:p></o:p></p></div><div><p class=MsoNormal><span style='color:windowtext'> </span><o:p></o:p></p></div><div><p class=MsoNormal><span style='color:windowtext'>Any recommendations? </span><o:p></o:p></p></div><div><p class=MsoNormal><span style='color:windowtext'> </span><o:p></o:p></p></div><div><p class=MsoNormal><span style='color:windowtext'>Thanks </span><o:p></o:p></p></div><div><p class=MsoNormal><span style='color:windowtext'> </span><o:p></o:p></p></div><div><p class=MsoNormal><span style='color:windowtext'>Jay</span><o:p></o:p></p></div><div><p class=MsoNormal><span style='color:windowtext'> </span><o:p></o:p></p></div><div><p class=MsoNormal><span style='color:windowtext'> </span><o:p></o:p></p></div><div><p class=MsoNormal><span style='color:windowtext'> </span><o:p></o:p></p></div></div></body></html>
