How did we get to be the global leaders in water, mixing and wastewater pumping? We launched the world’s first submersible pump for contaminated water as early as 1947. Since then, we have gone from strength to strength, offering both wet and dry installed pumps, mixers, pump stations, pump controls as well as driving key innovations within wastewater pumping and submersible mixers in wastewater treatment.
There has been no stopping the chain of groundbreaking innovations that have set standards for others to follow, from the invention of the first submersible pump to pioneering the use of submersible pumps in municipal wastewater networks and submersible mixers in wastewater treatment.
1930: Flygt’s first pump, the ‘universal pump’ was manufactured in Lindås.
1947: Development of a prototype for the first submersible drainage pump, also called the B-pump. This pump revolutionized the mining and construction industries.
1956: Launch of the submersible sewage pump, called the C-pump. Now pump stations could be much smaller which also lowers operational costs and makes servicing easier.
1956: Sales companies established around the world, making the Flygt pump available throughout Europe, America and Australia.
1958: The world’s first submersible mixer, SP300
1970’s: An expanding range of products were made available - from mixers, to manure pumps, large sewage pumps and propeller pumps.
1977: First submersible mixers for wastewater SR4500
1980: Development of the Flygt lift. Specially designed geometrical lifting device provided safe lowering and hauling of a pump below surface. Eliminated the need for a permanent lift chain as well as frequent pump inspections.
1983: Introduction of the Nevaclog impeller. A single vane impeller equipped with a hydrodynamic shape, which prevents objects being caught on the leading edge. Delivers higher reliability and less energy consumption.
1983: Development of the Grinder pump. This incorporates a cutting device in front of the impeller to grind all solid objects to be pumpable into small diameter pipes. Enables lower costs due to the smaller pipes required (pressurized sewage systems).
1984: Launch of the banana blade mixer. A large slow moving back-swept propeller which gives clog-free operations with a higher efficiency. Delivers higher reliability and lower energy consumption.
1984: The first ultra high effiency, submersible mixer SR440
1987: Development of the Flygt Subcab. These cables can handle liquid temperatures of up to 70° and water depths of 50 meters. A part of Flygt’s environmental program and deliver excellent insulation.
1992: The first high versatility SS-mixer, SR4600
1993: Introduction of the Flush valve. These open and close only by means of the pumped liquid. Self-operating which eliminates the need for power and control equipment needed previously.
1994: The manufacture of small and medium sized sewage pumps in China.
1994: Launch of the CP3800 – the biggest sewage pump to date.
1995: The one millionth sewage pump sold.
1996: TOP pump station. Designed with inclined walls that prevent solid materials from accumulating in the corners. Enables less maintenance and reduced odors.
1996: Launch of the Spin Out. A spiral groove that removes grit from the seal cavity. Allows for longer seal life and less maintenance.
1997: Launch of N-impeller. It effectively forces all obstacles through the pump. Also paves the way for highly efficient multi-vane impellers. Delivers improved efficiency and clog resistance along with lower maintenance and energy consumption.
1998: The two millionth pump was produced.
1998: The first jet-mixer for dry and submerged installations with N-technology
2000: Development of the Plug-In seal. Makes it almost impossible to mount incorrectly, enabling easier maintenance. Seal surfaces are also protecting during disassembly and mounting.
2004: Introduction of Duraspin. Suction lock protects the impeller from damaging particles. Provides for longer life of the impeller along with less maintenance and sustained performance.
2008: Launch of the N-chopper. An insert ring that together with the N-impeller chop larger obstacles. Makes for truly efficient chopper action and lower energy consumption.
2009: Introduction of Active seal. Delivers a pumping action from low to high pressure. Provides for less maintenance and increased reliability.
2009: Launch of Adaptive N-impeller. Gives improved clog resistance and less unplanned maintenance.
2009: The first high effiency submersible PM mixers
2010: The 200,000th mixer sold.
2011: Rotating shaft stabilizer and leveling flange with gas seal introduced for top entry agitators.
