ANDRITZ is one of the market leaders for the supply of plants, equipment, and services for hydropower stations globally. The portfolio includes high-quality large and standard pumps used in infrastructure projects for irrigation, desalination, and drinking water supplies, for example, and under its own technology brand “Metris – Foresee digitally” a wide range of innovative products and services in the area of Industrial Internet of Things (IIoT).

ANDRITZ has specialised early in the construction of large irrigation and drainage pumps. In the 1960s and 1970s, the company supplied various irrigation pumping stations in the Middle East and Africa, which are still in operation to the day. An area of 420,000 hectares, for example, is being irrigated with ANDRITZ pumps in Sudan alone. This roughly corresponds to the area of around 933,000 football fields.

Recent projects include, among others, the Indian infrastructure project JalaYagnam. ANDRITZ supports this endeavor in a total of eleven sub-projects. These include delivery of three vertical volute pumps for the Bheema project to irrigate 820 sq.km (203,000 acres) of land, five volute pumps for the Kalwakurthy pumping station with a total flow rate of 115 cubic metres per second as well as 27 vertical volute casing pumps for the largest subproject Kaleshwaram providing water for 736,345 hectares of agricultural land.
In the south of Alexandria, Egypt, 17 ANDRITZ vertical line shaft pumps are operating in a new pumping station supplying one of the main irrigation canals, the Nubaria Channel, with a total of 11.7 cu.m of water per second to irrigate more than 3200 sq.km in the future.

Tailored pump technology for Amu Bukhara
The pumps for the two pumping stations of Amu Bukhara are highly technical pumps whose development and production have been carried out according to the project-specific requirements. For the Kizil Tepa station, 10 tailor-made vertical volute pumps are being produced – each with an efficiency of up to 90 per cent. They reach a head of up to 75 meters and a flow rate of up to 440,000 cubic metres per hour.

For the second station, KuyuMazar, six customised vertical line shaft pumps are planned. They reach a head of up to 24 metres and a flow rate of up to 414,000 cubic metres per hour. These hydraulic machines are also designed to take into account the increasingly changing characteristics of the river. Equipped with a hydraulically adjustable mechanism, it is possible to vary the impeller’s angles up to 15 degree between minimum and maximum. Thus, it is possible to respond reliably and promptly to changes in the head and flow rate even during pump operation. Additionally, by varying the impeller diameter and the trailing edge, an exact adaptation to desired operating points can
be made and the efficiency can be optimised. This adjustment device has clear advantages when significant changes in the flow rate occur and is characterised by a long life with no need of any electronic spare parts.

Besides design and delivery of the pumps and spare parts, installation and commissioning work on site will also be supervised by ANDRITZ personnel. Completion of the entire project is scheduled for June 2020. Great hopes are being pinned on the success of this infrastructure project. Harnessing sufficient water reserves for reliable irrigation of agricultural land will bring sustainable changes for the better in the living conditions for future generations in the respective Uzbek provinces.
