Abstract
A modular liquid pump operable as a liquid pump when used by itself and as a foam pump when combined with a modular air pump is disclosed herein. In one embodiment, the modular liquid pump includes a housing for forming a least a portion of a liquid pump chamber; an inlet valve for allowing liquid into the liquid pump chamber; an outlet valve for allowing liquid out of the liquid pump chamber; and an attachment mechanism configured to secure the liquid pump housing to a modular air pump. The modular liquid pump operates alone to output a liquid or operates in combination with an air pump to output a foam. One embodiment includes a modular air pump configured to be secured to the modular liquid pump. In such a combination, the modular liquid pump and the air pump operate together to output a foam.
