i see.. there are units which can handle the flowrates. (but look at the
price..)
anyways.. you can't do this with some old garden hose.
these are special tubings which are constructed for compressing them tight.
maybe only buying the tube is within homebrew price range... not sure..
making a motor with rollers should be possible....

thanks for the link...
