[RE-wrenches] Pump power

Wrenchers,             We're upgrading an off-grid water system.  Dynamic head while pumping at 20 GPM is 150 ft from water level to wellhead and then its 85 ft vertical to storage tank so 235 ft total head to open discharge.  We would like to get most of that 20 GPM, we need to know if there

Hi Bill I would not recommend the Sqflex as it does have that gpm/height possibility but would recommend the Grundfos SQ. The 22SQ15-220 will do what you want. 1.5hp, soft start, 240vac, way less expensive, uses a bit more power. Jay Peltz power. > On Sep 22, 2020, at 1:10 PM, frenergy wro

The Grundfos 16SQF-10 will give you 12 to 13 gpm at 230 feet. But that is working at the upper edge of this pump's lift rating. Not sure that meets your definition of most of the 20 gpm. The maximum output current, 50 A, of the inverter system equals the locked rotor amps of a 2 HP motor. With

[RE-wrenches] Pentair Pump power

If you have 240 VAC look at the Pentair wild AC pumps I have one at 20 GPM and am a believer. Tapers on - soft start, varies the volts & amperage with flow and tapers the amperage down as it reaches a full expansion tank. Even better my local well pump installer sells & services it so I do not h

Just curious, the 120VAC 1/2 HP submersible that has to date been in the well for the last 17 years has needed zero service, is there something about the Pentair set-up you're referring to that needs regular or occasional service?  Believe me I understand your comment about schlepping service t
