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.
