I am trying to get my pool pump setup with the goal of balancing the run time, with energy savings, with water turn and in order to do this I need to know the GPM at any given RPM. It doesn’t have to be spot on accurate, just an estimate would be good to get me started.
Here is my setup:
Hayward SP3400VSP EcoStar pump
Hayward Pro-Grid DE Filter (48)
19,000 gal of water
AutoPilot Salt system
1.5” pipe everywhere
10 solar panels on my 1 story roof
Pump it about 20’ from the pool and about 45’ from the side of my house where to solar panels start
There is no spa, no water features, no heater…just a basic pump, filter, solar setup
I’d like to turn the pool 1-1.25 times in 12 hours. I’m in SoCal and want to take advantage of the sun/solar during the prime time of the day so I want to turn about 14K gal from 10:30am – 5:30pm and turn the remaining 5k-10k in the morning and the later evening.
Here are the stats I currently know: (the PSI is referring to a pressure gauge that sits on top of my DE filter) this is also running everything through my solar panels which is 80% of the year.
RPM – 1000 Watts – 69 PSI 0
RPM – 1725 Watts – 195 PSI 6
RPM – 2500 Watts – 580 PSI 14
RPM – 3250 Watts – 1260 PSI 25
Anything you can do to help me determine estimated GPM would be GREATLY appreciated.
