    So this is the side with two extra screws they say never open?

    No thats the 2nd stage. The side near the oil seal.

    Instructions.... If something says never do this, thats the first thing I do.

    The side with the extra screws - looks the same, but the vanes are 1/2 as wide, and the side of the vanes that contact the wall or more rounded.

    I never consulted with instructions... I tear down pumps all the time and I was planning to order the cartridge anyways, so I just went to town.

    Oh, great. Do you ever consult instructions?!

    Get away from my machine! Go water a lawn or something! : grin:

    So you just spun the second stage vanes 180?
    I think I'll try that but use the same oil.

    Hey where can i find that info on cfm through different sized hoses at 1000 microns, etc?

    Is there more to that available? Such as the ability to calculate "equivalent lengths" of the connections and piping, etc?

    I spun both sets of vanes 180

    But in the manner that keeps the shaft side still the shaft side, if that makes sense.

    The diameter is obviously effective diameter, not tube size.

    So 5/8 as an example would be 1/2
