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.
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.
Cooling water pump (CWP) for biomass wasteCooling water pumps for biomass firing applications are typically horizontal axially split or end suction type. Vertical turbine type pumps are also available when required.
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.
Crude oil pipeline mountainous terrainIn remote areas, there may not be power available, or, terrain may be so steep that all the pressure rise has to be made in 1 station. Each pump must make the entire head. Pumps are often run in parallel. Hundreds of Sulzer multistage pump performances meet such high pressure requirements.
Crude oil pipeline offshore to onshoreAll the pressure rise must be made in the crude shipping pumps on the platform. Salt spray is corrosive and platform movement during storms can affect reliability. Specially packaged Sulzer multistage pumps are used to move crude oil from offshore platforms to onshore storage or pipeline systems.
Crude oil pipeline onshore flat terrainPower cost is the largest operating cost for crude oil pipelines on flat terrain. Flow rate, viscosity, pipe size, and station spacing all affect pump selection. 2 or 3 mainline pumps are often run in series. Sulzer can help with FEED assistance, rerates to optimize performance and lower power costs.
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.
Liquefied petroleum gas pipelinesLiquefied Petroleum Gas (LPG) mixtures (ethane, propane, butane) can have vapor pressure up to 40 Bar, specific gravity less than 0.40, and almost no lubricity. Sulzer provides special materials, acoustic studies, and lateral analysis to assure reliable performance with varying flow, speed, and fluid conditions.
Refined product pipelinesThousands of Sulzer multistage pipeline pumps move diesel fuel, jet fuel, gasoline, and other refined products all over the globe. Sulzer’s global service centers, service and retrofit not only our own pumps, but other pumps and motors as well.
Seawater liftSea chest, lineshaft or electric submersible pumps. Whatever your seawater lift needs, Sulzer has a solution.
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.
Water transportationWater transport pumps are pumping large volumes of water over mostly long distances and high geodetic heights to geographical areas or industries where it is required for different purposes. We offer various configurations according to your needs.
