Flowserve Pump Division Receives Order For Thailandís Pasak River Dam Project


Flowserve Pump Division has announced it has been awarded an order by Thailandís Royal Irrigation Department for the Pasak River Dam project. The order for six vertical mixed flow pumps is valued at US $792,000 and will be delivered by December 2002.

These Flowserve vertical circulating pumps (type 50SKXH) are single stage models with semi-radial flow bowls. They will be applied in irrigation, drainage and flood control as required. Three pumps (Group A) will meet an initial nominal duty point of 42m (138ft) total differential head at 6325 m³/h (27,800gpm) and are driven by 900kW (1200hp) motors at 600 rpm. The remaining three pumps (Group B) will operate at 6225 m³/h (27,400gpm) at 47m (154ft) of head at 1000 kW (1350 hp).

This order is part of a 19.2 billion baht (approximately US $ 440 million) irrigation and environmental rehabitlitation and development program to minimize drought and flood problems in the 3.65 million acre Pasak River basin, north of Bangkok. The Pasak Cholasidh Dam is an earth fill dam with a 960 million cubic meter (25 trillion gallon) reservoir that will provide flood relief and an adequate water supply for Lop Buri, Saraburi and the neighbouring Chao Phraya River area. Group A pumps will take water from the reservoir and transport it along a 6.2 km (3.8 miles) long steel pipeline of 1.8m (6ft) diameter to provide irrigation to 11,720 acres of higher ground. Similarly, Group B pumps will taker water from the reservoir and transport it along 7.9km (4.9 miles) long steel pipeline of 1.8m (6ft) diameter to provide irrigation to 11,400 acres of land. Additionally, this project will support water transportation and fish conservation efforts for the region.
