Obviously, I am also building a spray etcher. I
searched through the message archives and I found
references to a couple of pumps (One was even
recommended...). However, upon examination of these
pumps (Using spec sheets published by the manufacturer
or by talking to manufacturer tech support) it became
obvious that they were not suitable due to either the
materials used in thier construction or not enough
pressure (GPH is never the problem). If anyone bought
those pumps, the etchant most definately destroyed the
shafts (Stainless 316) or the impellers (Delrin) or
both.
I have been looking at centerfuge pumps and diaphram
pumps (Just as you have). However, I have not looked
at the Shurflow or flowking lines (Although I'm gonna
take a look based on your recommendations).
I have found one pump that has suitable materials used
in the construction and produces the desired pressure.
However, it's a submersible and I'm not thrilled with
that (So, I'm not going to purchase it...). It was
$36.00 USD at my local hardware store.
Well Adam, it looks like you and I are breaking new
ground (At least for this list).
