The accumulator listed here is NOT 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.
