A foam pump, or squeeze foamer and dispensing device is a non-aerosol way of dispensing liquid materials. The foam pump outputs the liquid in the form of foam and it is operated by squeezing. The parts of the foam pump, mostly made from polypropylene (PP), are similar to those of other pump devices. The foaming pump often comes with a protective cap.

A foam pump dispenses doses of the liquid contained in the bottle in the form of foam. Foam is created in the foaming chamber. The liquid constituents are mixed in the foaming chamber and this is discharged through a nylon mesh. The neck finish size of a foam pump is bigger than the neck finish size of other types of pumps, to accommodate the foamer chamber.
