RUBBER HOSES

ZEESTER DIENSTEN supplies a large variety of rubber hoses, of various dimension and thickness, either for suction and discharge applications that are necessary for:
• Improving the flexibility of the pipeline;
• managing difference ground levels;
• assembling a sinking line;
• connecting the pipeline to the dredger pump;
• suction and discharge operations.

According to each specific application ZEESTER DIENSTEN supplies adequate and customised types of hoses considering specific working pressure of the pipeline, the type of sediment involved, the requested bending radius and the quantity of materials that need to be pumped. ZEESTER DIENSTEN experience in the dredging sector provides the necessary typology of hoses for any specific project. ZEESTER DIENSTEN studies and supplies a complete range of suction and discharge hoses, including
