Push actuated double fluid dispenser (1), comprising a container (2) having a first cavity (4a) and a second cavity (4b) separated from the cap first cavity (4a), and a dispensing pump device (6) in a general form of a cap assembled to the container over the first and second cavities, the dispensing pump device comprising a base part (7) and a cap part (8) including a pump mechanism (16) comprising an elastic flexible pump membrane (18) manually movable from an uncompressed state to a compressed state. The pump mechanism (16) further comprises a separating wall (20) extending from an underside of the pump membrane (18) and inserted into a slot in the base part, the separating wall separating a first pump chamber (22a) from a second pump chamber (22b), both first and second pump chambers provided in a volume below the pump membrane (18), the first pump chamber connected fluidically to a first inlet channel (10a) and a first outlet channel (11a), the second pump chamber connected fluidically to a second inlet channel (10b) and second outlet channel (11b), the inlet channels fluidically interconnecting the respective first and second cavities to the respective first and second pump chambers, valves (13) being positioned between the inlet channels and the pump chambers configured to allow fluid flow only in the direction from the cavities to the respective pump chambers, and the outlet channels interconnecting the pump chambers to an outlet nozzle (12) of the dispenser, outlet valves (24a, 24b) being positioned in the outlet channels configured to allow fluid flow only in the direction from the pump chambers to the outlet nozzle.
