Heavy Duty Slurry Pumps for Dredging, Mining, Steel and Power Dragflow was formed in the late 1980's as a manufacturer of high quality submersible dredging pumps for the European market. With early successes we expanded the product line to a full range of electric and hydraulic pumps and small turn key dredges. Through our commitment to quality products, dependable service and continuous improvement Dragflow has become established worldwide as the pump of choice for severe service conditions where other pumps fail.
