Cooling water pump (CWP) for gas-firedCooling water pumps (CWP) provide the fresh water to cool the exhaust steam in the condenser and pump it back to the wet cooling tower or the outlet of open cooling system. The major characteristic of the CWP is their high flow. In medium to large size gas-fired combined-cycle power plants, the CWP are vertical column type. In small power plants, the CWP could also be horizontal axially split type.
Cooling water pump for coal- and oil-firedCooling water pumps (CWP) provide fresh water to cool the exhaust steam in the condenser and pump it back to the wet cooling tower or the outlet of open cooling system. The major characteristic of the CWP is their high flow. In medium to large size coal- and oil-fired power plants, the CWP are vertical column type. In small coal and oil captive power plants, the CWP could also be horizontal axially split type.

12 million benefit from ambitious water pumping projectIn Brazil, the government has been looking to bring relief to a semi-arid area in the northeast of the country that is home to 12 million people. Sulzer designed and manufactured six of the largest pumps in the project, to transfer water from the São Francisco River to the drought-affected area.
Case studiesWherever fluids are pumped, mixed, controlled or applied, we are there. See how our solutions create value for customers and learn how we can make your pumping and mixing processes more efficient and profitable, safeguarding your production and ensuring lasting reliability.
Cooling water turnkey system for EDF's CCGT power plantEDF Energy’s combined-cycle gas turbine (CCGT) power plant at Bouchain in Northern France has already earned a place in the record books. Sulzer was contracted to deliver the design and manufacture two large cooling water pumps at Bouchain power plant. The scope of Sulzer's working including the desing of the suction take.
One supplier for all pump applicationsSulzer has been developing, designing, building and supporting pumps for power station applications for decades. The company’s pumps are used in almost every type of power plant, including nuclear, solar, gas-fired and biomass facilities. As such, it is the preferred supplier for some of the world’s largest and most demanding projects. Take the example of a major new project recently completed in Europe.
