A good pump like that would also be as much as many print washers I could buy.
Now to address the durability is another question. Im not going to just leave
it running 24 hours a day. It will be on a few hours at a time, worst case
senerio several times a week. I don't get to play in my darkroom every day. I
also plan on draining after each session.
The other thing is that the pump unlike may in its intended use is likely to be
used at a flow rate that is well under what it is likely capable of doing.
That also will keep the stress on the pump to a minimum.
Fish tank pumps are indeed designed to move water 24hours a day, and so are
pumps for fountains and ponds. Now will they take the demands?? That remains
to be seen, but as I learned with the sink you can overbuild just as easy as
underbuild.
The acid or possiblity of it should be something I can deal with potentially by
running a solution of water and baking soda through it, then rinsing if the
concentration levels get up. Its something I wouldn't have thought of had you
not said anything Frank.
Whether I agree or not is really not important. The discussion is making me
think. If the only way to make this workis a $200 pump, then the project goes
no further. There are other ways to go other than that.

A cheap Home Depot sump pump will cost maybe $50 and die in a year ( acid or
not, sump pumps are not made for running 100% of the
time, except for short intervals).......
Jim, it is his choice. Is it a valid choice? Yes, is it a prudent choice, you
and I would say not.

This one looks about right......, depending on flow rates....

You know the old saying:
Buy cheap, buy twice!
The problem with something breaking, or wearing
out, is that it ALWAYS happens at the most
inopportune time possible. I have long given-up
on buying cheap, whenever possible.
