ABSTRACT:
Centrifugal pump, in particular dredging pump for fluids containing abrasive solids and at times larger pieces, having an impeller closed at its two sides, which impeller is journalled at its two sides directly in the pump housing or extensions of the housing, without making use of separate bearing blocks; at the suction side of the impeller the bearing surface is formed on the outside of an interchangeable suction pipe stub (65) about 0.2-1.0 m or more in inside diameter. At the drive side a corresponding bearing structure (66, 662), fitted with axial bearings (663, 661) is used, all radial and axial bearings being fresh water lubricated and of purposely simple, interchangeable design. Against the closed side walls (61, 63) of the impeller, lip-type water lubricated seals are disposed in the vicinity of the outer diameter of the impeller. The pump housing is a welded substantially concentric cylindrical structure.
