    Confused

    ok ice....I guess the question that is still lingering with me is WHY his test isn't worth a crap. I mean as I stated before his test was far from scientific but seems to me that it gives a GENERAL idea of performance, the test conditions were virtually identical, the only variable it seems was the pump itself. Where am I missing it?

    Most commerical systems have king valves, yes I've learned that, I'm sure you remember my thread about the 404-a larkin freezer.

    No his test is not crap, just a little loose. The point I am trying to make is this : Does the pump do the job required or not. Hell I worked back in the '60s using a "Frigidaire Rotary Compressor" for a vacuum pump. Was this proper ? at the time I was still wet behind the ears, but when jobs started to go south I decide to educate myself to the best of my ability and with the "gurus" of this business and when I told my boss about what I learned, he listened and realized I was not a dumb a** kid.

    What Ice is basically saying, time has nothing to do with quality.
    Also that is a lot of money to spend when other vacuum pumps perform just as well.

    That was my point exactly! No way in hell I'm spending 800 bucks on a pump. My 7 cfm JB works just great.

    Also if u put pressure to it, it won't blow the oil all over the place.
    Do you mean that some of you have accidentally put pressure to a vacuum pump? That's crazy talk.

    You must store the pump in the side door well. Then you dump the pump.

    I USED to.

    Since then, I built a shelf for rec machine, vac pump and other tools.

    Haven't spilled pump oil that way in years.


    Dang!! Now I went and cursed myself.

    LOL, I learned the hard way too that you have to have a special space for your vacuum pump. I only did it once, but it made one heck of a mess back there.
