A device for pumping a liquid, utilizing the action caused by releasing compressed air or gas in the submerged end of a pipe. The air or gas aerates the liquid, causing it to become lighter by volume and is thereby forced upward in the pipe by the surrounding heavier liquid, thus producing a flow.
Classification: Hand- or foot-operated air pumps
