KSB pumps for Saudi power station
23 Apr 2010
Frankenthal, Germany – KSB Group has received a Euro1m order for five giant main cooling water pumps for a new 1,200 MW heavy-oil fuelled steam power station in Rabigh, Saudi Arabia. The pumps will be supplying the seawater needed for cooling the condensate circuit.
According to KSB, the order covers the supply of five vertical tubular casing pumps type SEZA 22-160, each with a flow rate of 15.5 cubic metres per second and a head to be overcome of just under 17 metres. Shipment of the first few units is scheduled to start in April 2011.
The units will be driven by vertical high-voltage motors with a rated power of 3,300 kW and an operating voltage of 13,800 volts each. With their 26 poles, the pumps are extremely slow-running and the propeller speed is 273 revolutions per minute.
Since the temperature of the seawater to be pumped can reach 32°C and as it is very aggressive, all metal parts in contact with it will be manufactured from seawater-resistant special steels, said KSB. The complete pump sets, it added, will have a total weight of around 130 tonnes and an overall height of almost 20 metres.
