Andritz will supply four two-stage vertical pumps for water transport as part of the Shanxi Xiaolangdi Yellow River Diversion Project in China.
With two reservoirs, several tunnels, underground canals, pumping stations, pipelines and aqueducts, the project is designed to handle and transport 247 million m3 of water annually.
Water from the Yellow River will be transported through a 6 km tunnel to an underground pumping station where it will be pumped over a distance of approximately 60 km by four Andritz two-stage vertical pumps into an artificial lake in the northwestern part of Shanxi Province. Each of these pumps will achieve a flow rate of 5 m3 per second over a head of 236 m and operate with an efficiency of over 91%. As the Yellow River transports large quantities of sand, the pumps have a special abrasion-resistant coating.
Andritz has provided pumps for other large-scale infrastructure projects in China. At the Hui Nan Zhuang Station, for example, eight Andritz horizontal double-flow split-case pumps supply drinking water to Beijing, while another 11 Andritz pumps of the same type operate in two stations that convey 200 000 m3 of water per hour from the Yellow River to the city of Hohhot, Inner Mongolia.
