A pump is any device for moving liquids and
gases, or compressing gases. Some pumps, such
as the traditional lift pump used to raise
water from wells, work by a reciprocating
(up-and-down) action. Movement of a piston in
a cylinder with a one-way valve creates a
partial vacuum in the cylinder, thereby
sucking water into it.
