Development history of submersible pump in the world

Development history of submersible pump in the world
   Submersible pump is a pump and motor combined into a special transport of liquid machinery, as the name suggests, mechanical and electrical integration into the water work. Its structure is simple, easy to use. With the development of material science, sealing technology, control and protection technology and the improvement of hot and cold processing technology, submersible pump has been developing rapidly.
    In 1904, the United States Byron Jackson (Byron Jackson) the first company to successfully design, manufacture a horizontal connection of the submersible pump and submersible motor, which is the modern submersible pump "ancestors." In 1928, the company invented the direct connection of the vertical submersible pump, which is the modern form of deep well submersible pump. Visible, the development of submersible pump has been 60 years of history.
    Sweden's Flygt (Sterbery Flygt), the first successful development in 1948 the world's first water supply and drainage with a shallow (or operating surface) submersible pump, fundamentally simplifies the pump type, the reform of the building foundation pit And mine drainage equipment, and soon in the world-wide success. In 1956, Flygt produced submersible pumps for sewage, which reduced the cost of sewage pumping stations by about half. In addition, Flygt has also solved a series of difficult problems, the development of a variety of special submersible pumps can be used to suck the abrasive liquid containing solid particles, viscous solution and corrosive liquids. In recent years, Flygt company in pump structure has made great progress, and the development of four series: pumping small particles containing abrasive liquid 2000 series, pumping civil and industrial wastewater 3000 series of large flow sewage submersible pump, pumping water Of the 5000 series, with a large flow of medium-lift screw (axial) type 7000 series.
