Nozzles

Hopper Nozzles

The efficiency of hopper discharge depends on the design, number, size and positioning of the nozzles combined with jet pump and jet water systems. The provision of a system completely tailored to the configuration of a vessel and its task is a key element in total added value.

Draghead nozzles

The nozzles used for the loosening and fluidising of bottom material are essentially of two types - integrated into the Weldmax block for maximum resistance to wear, and easily replaceable nozzles with stainless steel bushes. The nozzles on a draghead are set out across the full draghead width to optimise the fluidising process. Their diameter is typically a function of their number and the water pressure employed.
