    Stenner 45MHP10 flow settings FYI

    Not complicated math, but I thought I may save somebody a few minutes by posting this.

    Here are the ounces of chemical the pump will inject per hour at the different settings. Determine how much chemical you need to maintain your FC daily, and then you can run your pump at the listed settings to get yourself there.

    Setting 1 = 5.33 oz per hour
    Setting 2 = 10.67 oz per hour
    Setting 3 = 16 oz per hour
    Setting 4 = 21.33 oz per hour
    Setting 5 = 26.67 oz per hour
    Setting 6 = 32 oz per hour
    Setting 7 = 37.33 oz per hour
    Setting 8 = 42.67 oz per hour
    Setting 9 = 48 oz per hour
    Setting 10 = 53.33 oz per hour

    Will the flow rate go any lower than setting No. 1 at 5.33 oz/hour? That is a daily rate of 1.0 gpd and that pump is supposed to go as low as 0.5 gpd.

    The Stenner adjustable pumps have an "L" setting that's half of the "1" setting, so that's how they get the GPD.

    I created a spreadsheet for determining how much is injected per length of run time at the different settings, but this software won't let me attach it here.
