    An impeller is a rotating component of a centrifugal pump which transfers energy from the motor that drives the pump to the fluid being pumped by accelerating the fluid outwards from the center of rotation. The velocity achieved by the impeller transfers into pressure when the outward movement of the fluid is confined by the pump casing.

    A typical dredge might have a pump with a 12 (discharge) x 14 (suction) x 40 (impeller diameter) and therefore could be called either a 12 dredge or a 14 dredge. Dredges may have pump ports that are the same size, however, it is more common for the suction port to be one pipe size larger that the discharge port. Bigger is usually more impressive so sizing a dredge in reference to its pump inlet port
