(Ignore the lines labeled “38” VTD”, they refer to a 38” diameter impeller). Note that the two sets of curves are identical they project identical performance for the two pumps despite the difference in their port sizes. These curves project the performance of two standard Metso dredge pumps, one a 12” x 14” pump and the other a 14” x 16” pump. Bigger is usually more impressive so sizing a dredge in reference to its pump inlet port would seem natural. Others will say it is the diameter of the pump discharge port.Ī 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.ĭredges 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. When assessing a dredge one of the first questions that comes to mind is, “What size is it?” Some answer with the diameter of the suction pipe or the pump suction inlet diameter.
