However, this power level, you probably will have to settle for 1-ph. There is only one controller I know that can handle 1-ph motors. But there are some limitations, so I suggest that you call the company:</div><div><br></div><div><div style="display: block;"><div style="-webkit-user-select: all; -webkit-user-drag: element; display: inline-block;" class="apple-rich-link" draggable="true" role="link" data-url="http://www.enfusionenergy.com/"><a style="border-radius:10px;font-family:-apple-system, Helvetica, Arial, sans-serif;display:block;-webkit-user-select:none;width:228px;user-select:none;-webkit-user-modify:read-only;user-modify:read-only;overflow:hidden;text-decoration:none;" class="lp-rich-link" rel="nofollow" href="http://www.enfusionenergy.com/" dir="ltr" role="button" draggable="false" width="228"><table style="table-layout:fixed;border-collapse:collapse;width:228px;background-color:#E5E6E9;font-family:-apple-system, Helvetica, Arial, sans-serif;" class="lp-rich-link-emailBaseTable" cellpadding="0" cellspacing="0" border="0" width="228"><tbody><tr><td vertical-align="center" align="center"><img style="width:227px;filter:brightness(0.97);height:227px;" width="227" height="227" draggable="false" class="lp-rich-link-mediaImage" alt="dotted-bg.png" src="cid:B4A26D16-7BA8-4B54-BC66-27544BF81DE6"></td></tr><tr><td vertical-align="center"><table bgcolor="#E5E6E9" cellpadding="0" cellspacing="0" width="228" style="font-family:-apple-system, Helvetica, Arial, sans-serif;table-layout:fixed;background-color:rgba(229, 230, 233, 1);" class="lp-rich-link-captionBar"><tbody><tr><td style="padding:8px 0px 8px 0px;" class="lp-rich-link-captionBar-textStackItem"><div style="max-width:100%;margin:0px 16px 0px 16px;overflow:hidden;" class="lp-rich-link-captionBar-textStack"><div style="word-wrap:break-word;font-weight:500;font-size:12px;overflow:hidden;text-overflow:ellipsis;text-align:left;" class="lp-rich-link-captionBar-textStack-topCaption-leading"><a rel="nofollow" href="http://www.enfusionenergy.com/" style="text-decoration: none" draggable="false"><font color="#272727" style="color: rgba(0, 0, 0, 0.847059);">Home</font></a></div><div style="word-wrap:break-word;font-weight:400;font-size:11px;overflow:hidden;text-overflow:ellipsis;text-align:left;" class="lp-rich-link-captionBar-textStack-bottomCaption-leading"><a rel="nofollow" href="http://www.enfusionenergy.com/" style="text-decoration: none" draggable="false"><font color="#808080" style="color: rgba(0, 0, 0, 0.498039);">enfusionenergy.com</font></a></div></div></td></tr></tbody></table></td></tr></tbody></table></a></div></div> </div><div>Ask for Nikola.

The water will be cruddy so the pump would need to be able to tolerate that, although we will do our best to mitigate that. I'd like to be able to pump about 20,000 gallons per day or so at a head of 20'. My preference is no batteries but we could design in batteries.</div><div><br></div><div>Any input is appreciated!<br><div><div><br></div><span class="gmail_signature_prefix">--<span class="Apple-converted-space"> </span></span><br><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div><br></div><div><font color="#305A78" face="'times new roman', serif"><br></font></div><div><br></div>Mac Lewis</div></div></div></div></div></blockquote></div><br></body></html>
