company profile

HistoryDragflow S.r.l. was born at the end of the 1980’s as a manufacturer of heavy duty submersible agitator pumps specifically designed for handling slurries with a high content of abrasive solids.

Thanks to the passion and brilliance of its team of technicians and engineers, Dragflow S.r.l. has proven to be not just a simple alternative for handling solids with conventional products and systems, but provides solutions for those clients operating in specialised sectors who must face extreme conditions and solve very difficult applications. Many successful cases and customer satisfaction have encouraged us to continue with the research and further development of our products.

TechnologyAs a recognized leader in the production and marketing of submersible dredge pumps, Dragflow has gained over the years remarkable international experience and first rate reputation in the production of dredges, for marine and energy sectors as well as in mining for minerals and other materials.

The Dragflow team constantly works not only to find new technological solutions that improve the performance of its products, but also to design specific solutions for contractors and end users, optimizing sustainable operations with energy savings and reducing the environmental impact and overall costs.

QualityDragflow invested in ISO9001 Quality Certification and in its information systems, because it believes in the importance of business process management, not only for improving efficiency but also to provide excellent service to Customers.

features

ADVANCED DESIGNThe mixing and excavating movement is created by the Hi-CR steel agitator cutter blades. The agitator lifts and sucks settled sediments and solids, creating a continuous uninterrupted flow of concentrated slurry into the pump.

ABRASION RESISTANCELong life and performance reliability are guaranteed by robust, heavy-duty construction. Lower operating RPM and High Chrome wear parts guarantees lower wear rates and prolonged component life.

SOLIDS HANDLINGDragflow sand pump parts have been specially designed and shaped to provide outstanding performance, providing superb solids handling capabilities but with reduced wear (solid size up to 120 mm).
