What is a Foam Pump?
A foam pump is a specialized type of dispensing pump designed to transform a liquid soap, cleanser, or sanitizer into a rich, aerated foam. Instead of dispensing a stream of liquid, it dispenses a pre-lathered foam, which offers several benefits in terms of user experience, product efficiency, and hygiene.
How Does a Foam Pump Work? (The Mechanism)
The magic of a foam pump lies in its simple yet effective mechanical design. It works on the principle of air induction. Here's a step-by-step breakdown:
Priming: On the first few presses, the pump pulls liquid up from the bottle into its chamber.
Liquid and Air Intake: When you press down on the actuator (the head):
A piston inside the pump chamber forces a precise amount of liquid through a narrow passage.
Simultaneously, this action creates a vacuum that draws air into the pump chamber from the outside through a special air inlet valve.
Mixing: The liquid and air are forced together under pressure through a fine-mesh screen or mixing chamber.
Dispensing: This mixture of liquid and air is pushed through the nozzle, instantly creating a steady, creamy foam as it exits.
The entire process is mechanical and does not require a battery or power source.
