Pump dredges

We practice the design of mining systems of pump dredges, the development of design documentation, as well as the production of tools and equipment for dredge heads, which, depending on the mining conditions and the physical and mechanical characteristics of the extracted soil, can be equipped with jet pumps (ejectors), jet and other types of disintegrators. When designing dredge heads, we take into account the specific factors of the formation of erosion and suction flows in the underwater face. As a result of the head-capacity curve construction, we carry out the justification and selection of dredge and water pumps, pulp pipelines and water pipes, stop valves and testing instruments.

Our qualification in this area of activity is based on the completed dissertation researches, monographs, books, engineering calculation methods, scientific articles, as well as on many years of experience in the design of pump dredges and the presence of machines introduced into production.
