ABSTRACT:
A multiple stage jet proportioning and mixing pump system in which any variation occurring in the proportion ratio of the ultimate solution is confined essentially in the first proportioning stage operating at a low ratio below 1 to 5 with initial confluence of solvent and solute at substantially atmospheric pressure followed by the primary mixture being supplied to the second proportioning operation at a pressure preferably equal to that of the solvent jet at their confluence.
