Ultimate efficiency

Ultimate efficiency We have a deep attitude.

Growth of global population, tourism, transportation of people and goods together with increased awareness of the need to protect the planet are shaping the future of dredging technologies. Dredging is becoming a crucial activity for the development of our society. Creating new land or developing and maintaining an efficient harbour network, as well as restoring dam capacity and productivity or opening safe and efficient water-ways are basic activities to sustain economic growth in most countries. But more and more new challenges demand efficient and reliable dredging solutions such as the...

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...

Dredging with submersible pumps Unbeatable efficiency Dredging and solids reclamation are energy intensive operations. The main challenge for manufacturers of dredging equipment is to develop efficient machines that can reduce the use of energy and thus contain the operating cost of projects. Dragflow has been fully concentrated 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...

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 high efficient suction dredger. Design of dredgers comes out to be extremely simplified with 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...

Commercial Ports as well as tourist harbours water depth has to be maintained to keep the facility in full operation. Cleaning and maintenance of ports, marinas and waterways are therefore an important sector of activity for Dragflow and its customers. Harbor and Marina dredging Dragflow solutions are a competitive alternative to more traditional cutter suction dredges because the submersible agitator pump technology allows operators to keep a much higher solid concentration in the dredged slurry thus permitting lower operational cost per cubic meter of extracted material.

Land reclamation and coAstal protection Coastal protection has been the first application for Dragflow pumps. The 4000km of coast of the Italian peninsula cannot miss the appointment with the massive presence of international tourists in the summer seasons. For more than 25 years Dragflow has proudly played an important role to serve contractors providing a defence against flooding and the erosion of land. Dragflow has become a new standard along the years: thanks to the higher solid Channel and pond cleaning Thanks to Dragflow technology cleaning of ponds and waterways have never been so...

Off-Shore and High Depth Dredging System High depth projects can be very challenging not only for the high pressure environment where the pumps are required to work but also in terms of equipment installation and handling. Dragflow has not only the widest range of submersible dredge pumps and excavators that can work in high depth and deep-sea water (with successful projects up to 250m of working depth) but it is able to provide a complete tailor made solution that includes umbilical oil hose systems, hydraulic spoolers for oil hoses and hydraulic powerpacks for the offshore and oil & gas...

Dam cleaning is a crucial operation to keep the energy plant in a safe and efficient operating status. Dragflow can be a reliable and flexible partner for dam dredging projects thanks to quick delivery of high depth dredge system, remote controlled dredges or turnkey equipment for sediments removal.

With increase awareness of environmental problems specific jobs are now focused to cleaning up polluted materials in sections of ports and rivers within industrial areas. Dragflow submersible pumps are an ideal solution for such projects thanks to the low turbidity created during operations that allow remove contaminated sediments without harming the surrounding environment and to the high efficiency of the submersible pump technology that permit Environmental Dredging the lowest energy consumption per cubic meter of extracted material.

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 Civil Emergencies be a reliable integration for other OEMs. Dragflow works closely with its customers to ensure that its custom built equipment meet their individual requirements and expectations. Geotextiles filling Dragflow hydraulic pumps are ideal to fill-up geotextiles. Thanks to variable rotation speed of the pump the system production can be...
