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.

Pre-treatmentBefore reaching the RO Island, where specifically the desalination process will take place, raw water needs to be treated to ensure the required quality of the raw water to avoid fouling the RO membranes.
Product water transferAfter post treatment, product water is pumped to the storage tanks or into the water distribution networks.
Pulp drying machineIncreased hydraulic excellence for your approach, cleaning, drying machine, vacuum, broke, and white water system processes.
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 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 supplyMeeting today’s challenges and high requirements within water intake, sedimentation, sludge treatment, fine screening, and water distribution processes.
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.
