    Advice for a newbee- Just installed Intelliflo VS+SVRS

    Hi guys,

    Just joined, great forum and I've benefitted a lot already from the advice I've read.

    Wondering as to what the optimal RPM settings I should be running on my Intelliflo. I got a great deal on one from a maintenance outfit that was going out of business and installed myself. It replaces a 3/4 HP Whisperflo which was great, but in Northern California we get killed by our fine PUC which feels that charging $.49 per KWH is in our best interest and thought I'd invest in the Intelliflo.

    Anyhow, given our high cost of electricity, I need to do everything I can to optomize the power draw. I have an inground 28,000 gallon pool, with 1.5" plumbing, single inflow via skimmer (since main drain has long been sealed off) and dual 1/2" outflow jets (pool plumbing must have been designed in the dark ages). So the head (or whatever the measurement is of flow resistance) must be very high.

    I have a pressure side cleaner, with a seperate 3/4HP pump.

    Anyhow, I set up the schedule as follows, thinking it might be optimal, but wondering if someone could chime in with suggestions to optimize power efficiency.

    20 hours@ 1400 RPM
    2 hours@ 2000 RPM with booster pump running (so that skimmer skim's majority of stuff and cleaner runs)

    Figure that will get me close to a one turnover per day (given what I've read).

    Here's a table of the pump speeds/wattage/recorded pressure at filter
    RPM Watts P
    1100 145 0
    1200 153 1
    1300 170 2
    1400 170 3.5
    1500 247 4.5
    1600 292 5
    1700 336 6
    1800 387 7
    1900 446 7.5
    2000 513 8.5
    2100 580 9.5
    2200 658 10.5
    2300 745 11.5
    2400 841 12.5

    Below 1300rpm the power reading seems to fluctuate making me think that any speed much lower would be less efficient, but I could be wrong.

    Again, any suggestions on how to minimize power while keeping the pool clean are greatly appreciated.

    Thanks,
    Bob

    Welcome to TFP!

    You are definitely on the right track. From what I have seen, speeds right around 1000 RPM are ideal for the IntelliFlo pumps and short periods at a high speed are often needed to skim properly. For the higher speed period, I suggest that you split that into two one hour periods 12 hours apart, if you haven't already.

    Thank you Jason for the reply, and great idea about splitting the skimming times. I will do that today!

    I am so envious. I would love to have an intelliflo. Maybe you could ship me one

    My next project is working on some automation to switch the Intelliflo to power my Polaris 280 and get rid of the existing 3/4HP pump.

    The booster pump draws 9A at 240V (~2100W), so if I can power it just using the Intelliflow, maybe at 2400 RPM, I'm hoping to drop the load to about 800W. This would save about ~4.5KW/day, or about $60/month at the obscene amount charged by our utility theives.

    I'll let everyone know how it works out.
