A dosing pump according to an exemplary aspect of this disclosure includes, among other things, a first chamber having an outlet fluidly coupled to a mixing area, and a second chamber having an outlet fluidly coupled to the mixing area. The dosing pump further includes a piston moveable between a suction position and a discharge position.
