Ultimate efficiency

Ultimate efficiency We have a deep attitude.

Raw materials are vital for the global economy. Extraction, processing and cleaning are complex and costly activities that require reliable and efficient machines. Dragflow has been involved in the design and manufacture of mining pumps and dredging equipment for more than 25 years. Our equipment is used in process plants, tailings ponds, dam cleaning and dredge mining projects around the world. This experience has driven continuous development to reach the best solutions for the mining industry. In addition to submersible pumps for very heavy slurry, high head slurry pumps and dredges for...

About Dragflow Dragflow S.r.l. was born at the end of the 1980’s as Ultimate efficiency 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 specialized sectors who must face extreme conditions and solve very difficult applications. Many successful cases...

Technology As 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. Thanks to the experience in leading technology projects, Dragflow continuously enhances its ability to deliver high-quality products. People The Dragflow team constantly works not only to find new technological solutions that improve the performance of its products, but also to design...

at the heart OF MINING: advaNced aNd QualIty desIGN Strong and Reliable motors. Dragflow motors for mining pumps are all class H and have a minimum 1,25 service factor. They are designed for handling slurries with up to 1,7 specific gravity. low operating Rpm promotes low wear rates and extended component life. Best in class seal system. pumps are equipped with a unique lip seal system with a front deflector to prevent fine materials from penetrating the seal and Teflon layers to resist to high and low pH. Incredible high precision in the machining of parts together with grease injection...

draGFlOW OptIONs: OptIMIZe yOur puMp FOr yOur applIcatION Mechanical seal. Dragflow standard sealing system is its superb lip seals combination. a double silicon carbide mechanical seal in combination with a front deflector is available as an option for very abrasive applications. Cooling Jacket. Dragflow pumps from 3,7 to 18 kW come with top discharge that creates a natural cooling jacket for the pump. This allows the pump to work even if not completely submerged. an external cooling jacket can be applied also to pumps bigger than 26kW and up to 110 kW thus allowing all the range to work...

Trench and Pond Cleaning moving tailings and cleaning ponds around process plants is a crucial activity to keep the production process efficiently running. mining companies and contractors have come to trust the incredible heavyduty design of Dragflow submersible mining pumps. Dragflow pumps can be designed to work comfortably electrIc heavy duty puMps with slurry specific gravity up to 1,7 and in a very wide range of pH. a line of advanced control panels allows recording of the main operating parameters of the pump as well as monitoring of the pump operation from a remote location.

High Head and Heavy Dewatering Applications The new Dragflow HH line has set a new standard on the market: it has introduced the concept that submersible agitator slurry pumps can also have high head. 75m (246’) of head with ability to pump slurries with specific gravity up to 1,4. This value makes the HH the submersible heavy duty pump line with the highest head in the world. pumping tailings to a higher level or managing the most complex dewatering projects now have a new reliable efficient partner: Dragflow HH.

Hydraulic Motor Reliability and flexibility of hydraulic motors is widely recognized. Dragflow Pumps equipped with hydraulic motors can reach powers up to 400HP and work with variable RPM. No problems of loosing efficiency at different speeds combined with no problems of electroshock from electric devices makes hydraulic pumps the right choice for complex pumping and dredging applications. Dragflow double hydraulic excavators EXHY Dragflow hydraulic excavators EXHY20 and EXHY35 can be attached directly to the pump creating a self contained excavating system for hard compacted sand where a...

Dam and Tailing ponds Dredging Recovering the capacity of dams and tailing ponds is an essential operation to keep the processes and the mine running. Dragflow can be a reliable and flexible partner for mine dredging projects thanks to quick delivery of high depth dredge system, remote controlled dredges or turnkey equipment for sediments removal. In a process where keeping operational cost at the lowest level is crucial Dragflow solutions prove to be a competitive alternative to more traditional dredging technologies. a submersible agitator pump is able to move a much higher solid...

Oil Sands Oil sands is a growing industry that is increasingly demanding highly efficient and reliable technologies. Dragflow is a recognized supplier with installations in process plants and as a supplier of solutions for tailings management. as mining operations expand, it is necessary to build more and larger settling ponds. Finding a way to remove the mature fine tailings (mFT) layer from the ponds and quickly transform it into a soil-like deposit suitable for reclaiming is critical to improve overall reclamation performance. Dragflow has been working to optimize its dredging system in...
