Ultimate efficiency

Nearly two-thirds of the non-fuel minerals mined each year are aggregates. Dragflow has been involved in the design and manufacture of dredging equipment for the industry for more than 25 years. Our equipment is used in sand and gravel extraction operations, washing plants, tailings ponds, scale pits, bentonite recycling and dredge mining projects around the world. This experience has driven continuous development to reach the best solutions for the different industries. In addition to submersible pumps for very heavy slurry and dredges for wet sand mining and ponds, Dragflow has been...

About Dragflow Dragflow was born at the end of the 1980’s as a Ultimate efficiency 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 and...

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...

Unbeatable efficiency Dredging and solids reclamation are energy intensive operations. The main challenge for manufacturers of dredging equipment is to develop efficient machines that reduce use of energy and thus minimize the operating cost of projects. Dragflow has been fully concentrating on submersible dredge pump technology since the beginning and is now able to provide the widest range of electric and hydraulic submersible pump on the market. The presence of a double blade agitator together with pump suction directly in contact with the material make Dragflow pumps able to move...

High Versatility The Dragflow submersible dredge pump is a versatile tool. It can be attached to the boom of an excavator and run using the excavators hydraulics or it can be suspended from a crane or an A-frame to form a highly efficient suction dredge. Design of dredges becomes extremely simplified with the possibility to reduce capital cost and have high working depth without any increase in the cost of equipment. Pumps can be provided with cutter heads and thus form a submersible cutter dredger, with high pressure water jets to work in extremely concentrated mud or it can be equipped...

Sand and Gravel For sand and gravel applications efficiency is crucial. The cost per ton of extracted material can heavily change the profitability of the plant. Dragflow solutions prove to be a competitive alternative to more traditional cutter suction dredges because the wit h subme rsible pumps

submersible agitator pump technology allows a much higher solid concentration in the dredged slurry thus permitting lower operational cost per cubic meter of material extracted. This means it is possible to reduce discharge line diameter and water usage together with an overall reduction of fuel consumption per extracted ton. But Dragflow pumps are not only used for material extraction. The electric line is also widely used in washing plants and sludge ponds.

Sand washing and dewatering processes produce a highly abrasive sludge that has to be pumped to settling ponds or treatment plants. Dragflow heavy duty pumps are an ideal solution to guarantee long life even in the presence of high percentage of quartz.

Cleaning of tailings and industrial pits is an important operation to keep the production process going. Dragflow has become a new standard: thanks to the higher solid concentration provided by Dragflow technology it is possible to reduce usage of water or cope with extremely heavy slurries. Dragflow pumps can also be equipped with augers or cutters to be used in pumping organic materials or in presence of long vegetation. In addition to exceptional pumps Dragflow can provide remote controlled electric dredge: an efficient, simple and safe way to keep tailing and sediments under control....

Dragflow pumps and remote controlled dredges can be efficiently operated in sludge removal from biosolid lagoons thanks to their ability to handle abrasive solids and the option of a cutter-knife to chop organic materials. A mechanical excavator would otherwise be required.

Keeping bentonite moving in a safe and reliable way: this is one of the advantages of Dragflow pumps. Dragflow bentonite pumps are design to work in the most complex construction sites. Class “H” oversized motors and pressure compensation are two fundamental options that can make pumping bentonite from slurry walls more reliable than ever. Oversized motors give the pumps the ability to move slurries with specific gravity up to 1,6 or to be used well outside the best efficiency point without damaging the electric motor. Pressure compensators permit operating in bentonite applications with...

Dragflow has partnered with other manufacturers in the construction of complex machines to be used during civil emergencies and fire-fighting operations. Thanks to specific design capabilities of Dragflow engineering team our dredge systems can be a reliable integration for other OEMs. Dragflow works closely with its customers to ensure that its customand expectations. Civil Emergencies built equipment meet their individual requirements
