SAND GRAVEL PUMPS multi-functional HDP (Hydraulic Dredger Pumps)

NDS engineering offers you a wide range of pumps made of high-quality materials. Both the pump housings and the impeller are made of high-quality cast steel Max 5 to withstand the impact of larger stones that can break the housing wall.

Our pumps are under water and are extremely efficient for extracting and transporting gravel and sand. HDP Pumps have a capacity of 550 m3 / h to 3000 m3 / h. The pumps are also submerged and are very efficient even at greater depths. (10 meter) The pumps can be connected to various tools, allowing them to work more efficiently.
