ABSTRACT The invention is drawn to a mixing pump which can transport and effectively mix (homogenize) two or more liquids (or gases) in all ratios between the pure components. The ratio is constant, but is adjustable. This is effected by a double-acting pump cylinder (or two coupled, single-acting cylinders) which produces a charge of the mixture in a two-stroke-cycle. During the 1st stroke liquid (V1) is pumped from one side of the piston (2) through a restriction (12) (pressure drop) into the liquid (V2), while the liquid (V2) is sucked into the cylinder on the other side of the piston. During the 2nd stroke the mixture (V1 + V2) is pumped to a storage tank through a restriction (13) (pressure drop), while the liquid (V1) is sucked into the cylinder. By adjusting (by regulator 6), the amount of the liquid (V1) pumped into the liquid (V2), the pump can deliver any ratio of the two components. By choosing the velocity of the piston and of the coefficient of resistance of the restrictions, the necessary pressure drops for every purpose can be obtained.
