A bifurcated foam pump assembly for use in foam dispensers. A liquid dispensing portion of the foam pump assembly is attached to and disposable/replaceable with a liquid cartridge for the dispenser. The air compressor or air pump portion of the foam pump assembly comprises a portion of the dispenser itself and is attached to the dispenser housing. Upon replacement of a cartridge, the two portions mate and are operative as a foam pump generator. The liquid portion of the foam pump is received within a liquid chamber by gravity, and is subsequently driven from that chamber by air from the air compressor, which drives both the air and liquid through a foam generating member, such as a sponge or mesh. This foam generating member is a part of the liquid portion of the pump, and is replaced with the cartridge.
