Below is a list of 12 Volt Pump manufacturers from Grovetown, Georgia. A 12 volt pump uses centrifugal force to increase the pressure of a liquid by converting mechanical energy into rotational kinetic energy. Centrifugal pumps transport liquids by using pressure. Because they are relatively uncompressible, the liquids are not condensed or pressurized; instead they are imparted with centrifugal force, the force that causes substances to move away from their center of rotation.
