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-fired Cooling 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. Power plants Sulzer’s extensive product portfolio to maximize the performance and reliability of your solid organic fuel biomass power plant, solid industrial or municipal waste fuel biomass power plant, and liquid or gaseous organic fuel biomass power plant processes. Seawater lift Sea chest, lineshaft or electric submersible pumps. Whatever your seawater lift needs, Sulzer has a solution. Water intake Raw water to be desalted, either sea water or brackish water will be taken from natural resource and pumped to pre-treatment stage. For sea water abstraction, different intake arrangements can be considered, which will define the pump type to be installed. Water supply Meeting today’s challenges and high requirements within water intake, sedimentation, sludge treatment, fine screening, and water distribution processes. Show all Case studies 12 million benefit from ambitious water pumping project In 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 studies Wherever 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 plant EDF 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 applications Sulzer 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.
