KSB has been contracted to supply 22 power station pumps for the new Vietnamese Long Phu-1 power plant. The plant’s two 600 MW units are currently being built by a Russian engineering contractor. The complex is situated 20 kilometres east of Soc Trang city, on the right bank of the Hau River.
Included in the order are six boiler feed pump sets. The main and associated booster pumps are driven by 15,200 kW high-voltage electric motors. A geared variable speed coupling installed between the main pump and the motor varies the speed to achieve different operating parameters. Each pump set has been designed for a maximum flow rate of 1,200 m³/h and a head of 4,400 m. The boiler feed water temperature is expected to be 175 °C. To reduce energy consumption, the seven-stage pumps are equipped with optimised hydraulic systems which have proven their quality many times over.
