Applications
  • Cooling water pump (CWP) for biomass waste
    Cooling 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-fired
    Cooling 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 plants
    Sulzer 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-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.

  • Cooling water pump for heliostat central tower with direct steam generation
    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. CWP are vertical column type. In small plants, they can be horizontal axially split type.

  • Paper and board machine and systems
    Sulzer’s extensive product portfolio is designed to meet the most demanding hydraulic coverage requirements and for all types of liquids, making it ideal for challenging pumping, agitation, and mixing operations in stock preparation, PM approach system, broke system, white water system, vacuum system, condensate system, and shower water system processes.

  • 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.

  • Pre-treatment
    Before 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 transfer
    After post treatment, product water is pumped to the storage tanks or into the water distribution networks.

  • Pulp drying machine
    Increased hydraulic excellence for your approach, cleaning, drying machine, vacuum, broke, and white water system processes.

  • Water intake
    Water 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 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.

  • Water transportation
    Water 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.
