1.5meters is 0.15bar, while 1bar is more or less the lower, lower limit of
reasonable spray etching pressure.
(and the 1.5 meters is usually at almost zero volume)
We were not talking about only pumping, we need pressure for spraying.
But thanks anyway, your pump shows there are etchant-compatible pumps out
there, just not suited for spraying.
