Below is a list of Axial Flow Pumps manufacturers from Grand Rapids, Michigan. Axial flow pumps are machines that convert mechanical energy into kinetic energy by increasing the pressure of a liquid through centrifugal force. Liquids are virtually uncompressible so they themselves cannot be pressurized and reduced in volume. They can, however, be influenced by centrifugal force, the force that causes substances to move away from their center of rotation; they submit to the pressure of this force and are directed into, through and out of the pump.
