Hydraulic pump for dredging in a hydroelectric basin


Hydraulic pump for dredging in a hydroelectric basin

Dragflow supplied the equipment to carry out dredging works at a dam in Italy. Sediment accumulation in hydroelectric basins has now become a widespread phenomenon and jeopardizes both the capacity and the correct functioning of the plants. The managing bodies find it difficult to keep the unloading and derivation works functional with traditional methodologies that can be expensive or not respectful of environmental constraints.


The end customer needed efficient equipment for dredging works within the hydroelectric basin. The significant difference in level and type of mixture (composed of silt, sand and a small amount of gravel) required resistant and reliable equipment.


We have provided a complete package to correctly tackle the task: HY85/160 hydraulic pump equipped with EXHY20 side cutters, jet ring and diesel power pack. Furthermore, to ensure the correct functioning of the system, we assisted the end customer in the installation and testing of the equipment: dry assembly of excavators on the main pump; dry test of all machines; water test without drain hose; drain hose connection; diesel engine test; assembly of Dragflow equipment on the existing pontoon.
