    SuperFlo VS RPM vs Watts

    For anyone that has the Pentair SuperFlow VS 1.5HP pump, would you do me a huge favor? Can you run your pump at various RPMs from lowest to highest and let me know what the watt use is at each setting?

    That would be super-helpful for anyone looking into a VS pump! These numbers exist here for the IntelliFlo 3hp pump, but not for this one, thanks!

    Re: SuperFlo VS RPM vs Watts

    I just ordered that pump the other day. It's supposed to be here Friday and I plan to install it right away.
    If you haven't got your answer by then, I'm sure I'll be testing many different settings over the weekend.

    Re: SuperFlo VS RPM vs Watts

    500 rpm - 77 watts
    750 - 108
    1000 - 143
    1250 - 186
    1500 - 246
    1750 - 336
    2000 - 450
    2250 - 596
    2500 - 783
    2750 - 1000
    3000 - 1260
    3450 - 1950

    Your numbers may vary depending on you plumbing. I have 1.5" ridgid. PVC

    Re: SuperFlo VS RPM vs Watts

    Those numbers are really close to the 3hp IntelliFlo pump from Intelliflo VS (011018) RPM / watts to GPM

    RPM for RPM, I would have guessed a pump half the size would have used half the power. Hmm.

    (copy-pasted from the IntelliFlo thread)
    RPM WATTS

    1800 388
    2000 519
    2200 660
    2400 845
    2600 1050

    Re: SuperFlo VS RPM vs Watts

    Don't forget that those numbers are dependent upon the plumbing that the pump is running on so it will not be the same for every pool.

    Any difference if wired 125 or 230?

    Re: SuperFlo VS RPM vs Watts

    Energy use should be nearly identical for both voltages

    Re: SuperFlo VS RPM vs Watts

    As mas and I said it has a lot to do with the plumbing. At 2500rpm my filter pressure was 25psi and that's a clean filter number. Even as low as 1500rpm I still get 5 psi on clean filter. I didn't look at the pressure at max speed because it was only up that high long enough to get a wattage number. I only have a single 3/4" return eyeball fitting in my pool there is only so much water you can squeeze thru it.

    Not that the voltage will affect the numbers you get, my pump is wired 220v.

    Re: SuperFlo VS RPM vs Watts

    Does it though? Flow rate will vary significantly based on plumbing. But at the same RPM, wattage will decrease with head loss not increase. BTW: thank you very much for the numbers!

    Didn't you just answer yes to your own question? Or were you asking a different question?

    Re: SuperFlo VS RPM vs Watts

    Not really. RPM for RPM, the difference in wattage between no flow (0 gpm) and tons of flow (160gpm) in your spreadsheet is less than 2x in all cases. And the difference in wattage between the 0gpm and 50gpm case (normal flow through a residential pool) results in a 30% difference in wattage.

    The difference in flow in all these cases is enormous.

    So, differences in plumbing will certainly have an effect on these wattage numbers, but not a huge one. Good enough that I'd trust them to be applicable to my pool!

    Re: SuperFlo VS RPM vs Watts

    Flow has less effect on wattage than pressure. But yes if you have similar plumbing you will get similar numbers.

    Re: SuperFlo VS RPM vs Watts

    Rollercoastr posted in another thread:

    I run it at 2,800 RPM which pulls 1,080 watts

    This is very close to what CJadamec posted above.

    Rollercoastr, would you be willing to post more rpm vs watts numbers for this pump?

    TCpoolnoob, have you got yours installed?

    Based on the above, I'm probably going to go with this pump over the IntelliFlo. Also what's good with this pump is it can do basic automation without requiring any Pentair controller components (more $$$$)

    Re: SuperFlo VS RPM vs Watts

    If you want to know the wattage at any RPM on any type of plumbing, you can use the spreadsheet in my signature. You can even estimate the plumbing curve for your own plumbing to get more accurate energy use for your situation. Plus you can compare the economics between multiple VS pumps.

    Re: SuperFlo VS RPM vs Watts

    Here's my data from my SuperFlo VS today. I can't explain why it's using less power than the last time I looked... the water is warmer, but pressure is higher, as I've added DE to my sand filter...

    Re: SuperFlo VS RPM vs Watts

    Warmer water is less dense and will use slightly less power at the same flow rate.

    Higher pressure will slow flow rate and reduce power usage.
