Simultaneous pump dispenser of the trigger-sprayer type has a single container with separate liquid compartments. Side-by-side main cylinders in the dispenser body have vent cylinders there-adjacent. Pistons in all cylinders are worked together by a piston/nozzle assembly separately to pump the liquids and vent the containers. A manifold in the top of the container connects supply tubes and vents in the compartments to the risers and vent passageways for the respective main and vent cylinders. The discharge may be separate spray orifices, a single spray orifice combining the liquids or a single foaming orifice.
