ANDRITZ pumps for water and waste water applications

ANDRITZ pumps: water supply from Las Vegas to Beijing

The global pump specialists at international technology Group ANDRITZ offer comprehensive solutions for water supply, irrigation and drainage with their pumps.

It is becoming increasingly difficult all over the world to provide the population with clean drinking water in some regions. Growing cities, climate change, and settlements in previously undeveloped areas are three of the main reasons for this. International technology Group ANDRITZ offers pump solutions that are used all over the world to guarantee the water supply.

Drinking water supply: Las Vegas, USA

The US metropolis Las Vegas lies in a desert region and draws 90 percent of its drinking water from the neighboring Lake Mead. In order to guarantee the water supply for the population of around 600,000 inhabitants and just under 40 million visitors every year, and also to make the supply more efficient, the South Nevada Water Authority implemented the know-how and technology of ANDRITZ in 2008. Since then, three large double-suction submersible motor pumps with more than 11,000 PS designed and manufactured by ANDRITZ Ritz pump the water (17,200 m³) from a depth of 80 meters up to this city in the desert. Easy installation, freedom from maintenance, and, above all, the performance of the pumps make the plant particularly efficient. The impellers are made of precision investment casting and arranged opposite one other so that the axial forces cancel each other out. In addition, the double-flow technology halves the suction speed, causing less solids and suspended substances to be sucked in. In turn, this effect substantially increases the lifetime of the pumps.

Drinking water supply: Beijing, China

The Hui Nan Zhuang pumping station in the southwestern part of the Chinese capital Beijing (11.5 million inhabitants) has eight horizontal double-flow split case pumps. They press a total of 60 cubic meters of water per second into two pipes that convey the drinking water to Beijing 60 kilometers away. The pipes, each with a diameter of four meters, are fed by three pumps, with the fourth unit in each case as standby, which can be activated immediately in an emergency. Hui Nan Zhuang is the only pumping station in the central water supply channel for the South Water to North China scheme, a once-in-a-century undertaking. The channel is approx. 1200 km long. 

Drinking water supply: Guangzhou, China

Guangzhou in southeastern China numbers among the fastest growing cities in the country – the current level of around 12 million inhabitants is expected to reach as much as 18 million by the year 2020 according to researchers. This also presents enormous challenges for the drinking water supply. The city's authorities meet this challenge with ANDRITZ technology. In a local pumping station, a total of ten ANDRITZ double-flow pumps have been in operation since 2010, and two more have been installed as stand-by units. The pumping station conveys around 45 cubic meters of water per second into the city. On its journey there, the water covers a distance of around 40 kilometers and a height difference of 40 meters.

Irrigation pumps for an agriculture project in Andhra Pradesh, India

The Indian state of Andhra Pradesh, where 70 percent of the just under 85 million inhabitants live directly or indirectly from agriculture, is hit again and again by widespread and long-term periods of drought. As a result, the Indian government launched a project to irrigate all of the agricultural land. One of the most important partners is ANDRITZ. The Group is involved in a total of eleven sub-projects and contributes components for numerous pumping stations. The supply, for example, includes ANDRITZ vertical line shaft pumps. It would only take three of these large vertical line shaft pumps, with an impeller diameter of up to four meters, to fill an Olympic swimming pool with 2,500 m³ of water in under 20 seconds!
