Important things to consider
The accumulator listed here is
the same one I have. Mine is no
longer available. There are many variations on the web page, and I
urge you to be sure that the one you order has the right capacity to
handle your project. Mine is approximately 2 quarts. I do not have
a good working knowledge, but I have been advised that one does
not need a large volume accumulator to be functional. The main
function is to maintain a relatively constant pressure and to absorb
abrupt changes when the valves are actuated.
Also, you do not need to purchase a Power Pack. You can assemble
your own pump, motor, and reservoir to suit your needs. The one I
have is set to bypass at 2000 PSI.
