Homebrew PCBs

The pump sounds like its designed for chemicals. HCl + CuCl will be just 
fine, but I'd be more worried if you have enough pressure to properly 
power spray nozzles. I wanted to do similar thing with the mag. drive 
pumps I own but learned most spray nozzles need pressures above 10 
meters head. Spraying uses up a lot of  pump energy.
