Abstract
Pumping and foaming device (100) comprising a container compartment (20) where a foamable fluid (1) is stored, an air entry (13) through which air is provided into the device (100) and a processing compartment (10) where fluid is pumped and foamed with air, the processing compartment (10) comprising at least one movable part and a static part, movable with respect to each other; said parts being arranged in such a way that their relative movement pumps fluid by suction from the container compartment (20) respectively into the processing compartment (10), and also drives the mixture of air and fluid through a thin gap providing a certain level of shear stress which allows this mixture to foam.
