It’s too bad that Lorentz has come and gone a few times. I do like the architecture with the electronics all at the surface. And that the old ones had a easy manual speed control. The property has a sqflex in another well so I’ll just work on some options to get the flow as close as I can for

Jay, Lorentz still has two people in texas. I can’t find an active dealer but they do provide excellent tech support 24/7. I have to buy from a dealer but the ones that I have called only get one if specified on a new well they are drilling. They didn’t know much about them. John B On Tue, Ju

Jay, Running a Grundfos pump on low voltage also means running it on limited input power (the current can't/won't exceed a certain amount). It is easy to end up with a pump that won't operate all of the time, or only for a limited amount of hours every day. A pump that has a speed control is

I have been using this one for too many years. You need more than this Jay? https://www.pumpsok.com/sites/pumpsok/uploads/documents/water_systems/flexnew.pdf My dealer stopped selling Lornetz and not sure why? Dave Angelini Offgrid Solar "we go where powerlines don't" http://members.sti.net/offgr

Does anyone have or know where I can get the pump curves with voltages? I’m trying to limit flow by lowering the voltage, which I know works, but I can’t find the output vs voltage charts. And does anyone know if Lorentz is still active in the USA? The last time i checked their controller had
