12 million benefit from ambitious water pumping projectJune 24, 2020In 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.
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.
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 (CWP) for geothermal plantsSulzer offers a variety of cooling water pumps, all made to provide your processes with the optimum temperatures for your processes. Installed in a water cooled condenser, the pumps will be active for your specific process.
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.
Cooling water pump for heliostat central tower with direct steam generationCooling 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. CWP are vertical column type. In small plants, they can be horizontal axially split type.
IrrigationWe provide pumps for the water supply for gravity and pressurized irrigation systems. For these applications, we offer vertical and horizontal pumps that are especially constructed to highly challenging pumping and energy efficiency requirements.
Water intakeRaw 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 intakeWater supply is vital for our daily life. To abstract the water at the source, be it the sea, river, lake or dam, water intake pumps are needed. Sulzer offers a range of pumps that are specially engineered for such applications.
