The suction head is mounted on a hydraulic controller arm and at the inlet opening is provided with mechanical and hydraulic devices to disintegrate solid material (sediment). The hydraulic device includes a number of jet nozzles, while the mechanical device includes bars. The cross-sectional area of the inlet opening is larger than the cross-sectional area of the outlet opening.
