Zusammenfassung:	A rotary blade (18) is provided on the suction side of the pump casing (2) in an upstream position relative to the pump fan (20, 21). The pump casing has a bearing side which can be connected to a bearing housing (7) containing the pump shaft on which the fan is mounted. A suction connection is axially mounted inside the pump casing. An outlet (28) is located next to the fan periphery. A drive mechanism (12) is provided for the pump shaft. An independent claim is also included for a vehicle fitted with the dredger so that the suction side of the latter can be placed inside the medium requiring dredging.
