Dredge pump for sand and gravel extraction. For the hydraulic transport of solid materials like sand and gravel, the HEPU Company has developed special impellers that guarantee disturbance-free extraction operation depending on the deposit and mixture of the wear-causing medium to be pumped.
Because of the long practical experience of our engineers in the field of solid-material pumping, a new generation of dredge pumps using the proven HEPU pump construction has arisen: type „HEPU-SBP“. In addition to the extraction of sand and gravel, these pumps are also used for pumping ore suspensions, coal, mining waste, lime sludge, and other abrasive solid mixtures.
They are characterized by:
The hydrocyclone is a classifying device of simple construction. It is used for solid-fluid-separation in fine sand recovery. Through the appropriate inlet pressure, produced by an upstream HEPU pump, the solid particles in the suspension are separated on the basis of their weight difference from the fluid. Thus you receive an overflow that is almost clear. The outsize tolerance in the overflow lies between 1% and 5%.
