Dredge Pump Production For Cutter Suction Dredger Using A Long Distance Pipeline


A centrifugal sand dredge pump that is used for cutter suction dredger is often to transport dredged material in a long distance pipeline, and/or a booster pump is required.


When selecting the main dredge pump, ladder pump, booster pump, it is important to locate the dredge pump at an optimum position along with the pipe, in order to estimate the pump dredge production.


A program of dredging-production-estimation is going to be described in Do Dredge Pump Blog to determine the best location for each sand pump to estimate production ability.


For ladder pump and the booster pump, the consideration of pump cavitation and the power limitation of the pump are going to determine the location of pump.


Corresponding pump head curve, transfer distance VS pump head, pipe diameter VS slurry transfer speed, the system head curve, the available NPSH (Net Positive Suction Head) curve, the required NPSH curve and critical pump capacity are used for operating flow rate and sand production output determination.


The input of cutter suction dredger includes the water depth, the location of main pump, ladder pump, booster pump, pump rotating speed, sand pump horsepower, CV specific gravity of the sand slurry, the length of the discharge pipeline, inlet diameter of the HDPE pipe, the length of suction rubber hose.
