A wide range Flygt's 3000 Series small and medium-sized pumps finds application in sewage pumping, treatment plants, stormwater pumping, irrigation and in industry. A look at the features that make them suitable for these applications. FLYGT of Sweden, a leader in providing environmental solutions for municipalities, governments and the private sector, is offering a series of small and medium-sized pumps which can be used in a variety of applications and covers an extensive performance range.

The Flygt 3000 Series pumps are designed around a modular system with a common drive unit and a variety of hydraulic systems for various applications.

Primary areas of use are in sewage pumping and treatment plants. But the 3000 Series pumps also find wide use in other municipal applications, such as storm water pumping and irrigation, and in industry and agriculture, says Richard Denton of Medco, Flygt's distributor in Saudi Arabia.

The standard versions of the 3000 Series pumps are built of cast iron. All surfaces that come in contact with the pumped liquids are treated with a water-based acrylic primer and given a two-component high-solid finish coating.

Special finishes and zinc anodes for cathodic protection can be supplied on request. For applications in explosive environments, most models can be supplied in EX-approved (explosion-proof) versions. Special models in stainless steel are available for corrosive applications.

The maximum pumped-liquid temperature for the standard and explosion-proof models is 40 deg C, but special versions are available for temperatures up to 90 deg C.

All pumps in the 3000 Series come equipped with stator-winding over temperature monitoring. On request, oil condition and stator housing-leakage sensors can be built in. Flygt can also provide a number of additional products aimed at ensuring trouble-free pumping; these include flush valves, level regulators, alarm and monitoring systems and lifting aids.

Medco, in addition to other major projects, recently supplied pumping equipment worth more than SR2 million ($540,000) to Al Hasa-based Hussein Al Ali for municipal pumping stations in the region.

Founded in 1901 and based in Solna, Sweden, approximately half of the products that Flygt sells are used in the transportation and treatment of contaminated sewage water and industrial effluents. Because of this close association with water pollution control, Flygt is well-known as a leader in providing environmental solutions, says Denton.

The company also sponsors the Stockholm Water Prize, a $150,000 award given annually to honour outstanding contributions to water science and positive efforts aimed at alleviating the global water crisis.

Offering a strong product mix of submersible pumps, mixers and hydro-turbine generators, Flygt has approximately 3,700 employees, with subsidiaries in some 30 countries and active representation in just under 100 countries.

The company's pioneering efforts in fluid handling began in the 1940s, and led to the development of the first submersible, close-coupled, motor-driven pump affectionately known as the "parrot cage."

Denton says: "As the distributor for Flygt, we are involved in a broad spectrum of activities aimed at helping municipalities and contractors' engineers to improve sewage handling, flood control, energy conservation and tunnel construction. We also supply Flygt technology to industries such as mining, industrial processes, agriculture and aquaculture."
