Centrifugal Pumps

A centrifugal pump uses centrifugal force to push and move water (or other liquids) through pipe work such as a central heating system. Dictionary Reference.com describes centrifugal force as follows: "an outward force on a body rotating about an axis, assumed equal and opposite to the centripetal force and postulated to account for the phenomena seen by an observer in the rotating body."

A single impeller (a rotor designed to increase pressure and flow ofliquid inside a tube) is usually found in a centrifugal pump but it's not unknown for multiple impellers to be used.

Some of the most common uses of a centrifugal pump are in central heating systems; shallow well pumping and they are also used by fire protection services.
