The dredger pump is the main supporting equipment of the dredger. It mainly uses the movement of water to accomplish the purpose of dredging. It loosens the underwater soil layer through mechanical or high-pressure water cutting, so that the sediment and water are mixed to form a certain concentration. The mud-water mixture (mud) is then sucked into the mud pump through the suction vacuum of the mud pump installed on the ship, and then discharged to the mud tank of the dredger or directly to the side mud barge or transported to the blowing and filling area through the mud discharge pipeline. The purpose of dredging and filling was achieved. This type of hydrodynamic dredger is currently mainly divided into rake suction type, cutter suction type, bucket wheel type, suction cup type, blowing (suction) mud type, jet type, etc.
