Eight Giant Pumps for China
In mid-December 2005, KSB Aktiengesellschaft, Frankenthal, Germany, will be shipping out two of the biggest cooling water pumps the company ever built. The pump's installed depth below the installation level will be about 18m.

Each unit weighs nearly 130 tonnes, with the 4,600-kW electric motor alone accounting for 50 tonnes. Running at their design speed of roughly 300 rpm, each pump will deliver more than 16,000 litres of seawater per second at a discharge head of just 22 metres. The pumps' medium-lubricated ceramic plain bearings need no external water supply for starting and running.
Since the seawater to be pumped is very aggressive, all wetted parts are made of high-quality duplex stainless steel. Back in August of 2004, KSB received the order for a total of eight such units from Huaneng Power International, Inc. in China. When finished, Yuhuan Power Station will comprise four supercritical 1,000-MW units and constitute one of the world's most modern power plants.
