"Ultimate efficiency"
Italian manufacturer of heavy-duty submersible slurry pumps, dredging pumps and complete dredging equipment for mining, industrial and offshore use. Dragflow started in the 1980s making heavy-duty submersible pumps and has grown into a specialist in solid-pumping solutions, offering pumps together with dredges, excavator attachments and hydraulic power packs, with about 5% of turnover invested in research and development. Design, manufacturing and testing take place at the Italian production site near Verona; headquarters are in Roverbella (Mantua). The pump programme consists of electric submersible pumps (EL series, 3.7 to 240 kW) and hydraulically driven submersible pumps (HY series, 13 to 475 kW) with low-speed, wear-resistant high-chrome agitators and hydraulics that pump mixtures of up to 70% solids and solids up to 120 mm. The company is certified to ISO 9001, ISO 14001 and ISO 45001, holds TÜV Rheinland certification, and sells through a network of more than 67 distributors on five continents.

Product portfolio
2+ product families. Dragflow submersible dredge and slurry pumps are built for heavily loaded and abrasive mixtures: a high-efficiency reversible high-chrome agitator lifts deposited sediments, and a low rotational speed reduces wear. EL electric models (EL5 to EL1506) range from 3.7 to 240 kW, 30 to 1,700 m³/h, heads up to 72 m and solids up to 120 mm, in 50 Hz and 60 Hz versions with an Acid Proof option; HY hydraulic models (HY18 to HY600) are driven by hydraulic power packs, cover 13 to 475 kW, 50 to 2,300 m³/h, heads up to 70 m and are used on small, medium (DRH series) and large dredges. Pumps are designed for pH 2 to 10 and very deep seabeds.
