Pumps, Wells, Tanks, Controls / CSV in conjunction with VFD

« on: April 03, 2019, 11:58:08 AM »

Hi,  I am working on an irrigation installation that utilizes a 7.5hp booster pump running off of a vfd.  The VFD is necessary as it is being used as a phase converter to run the 3ph pump on a single phase residential electrical service and will also be varying pump output as needed by differing water needs.  There is also a 119 gal. pressure tank to supply instant pressure for incidental water uses.  This will be a constant on system with a pressure sensor to kick on the booster pump when a water use is sensed.   Big question is, would a CSV be an advantage in this configuration?  Details are 0-100 gpm @ 75psi.
