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.

  • Irrigation
    We 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.

  • Multi Effect Distillation MED
    Multi Effect Distillation (MED) process is based on iterative evaporation-condensation process in several stages under vacuum conditions, using residual steam from adjacent power plant as heating media for evaporation.

  • Municipal clean water supply and distribution
    Getting drinking water to all parts of a distribution network involves many challenges along the way. From the water treatment plant through pumping stations and beyond, Sulzer pumps lift and move the drinking water to bring it to its destination at sufficient flow and pressure.

  • Municipal clean water treatment
    When planning new water treatment plants or upgrading existing ones, operating costs are as important as investment costs. Sulzer’s innovative pumps, mixers and compressors combine reliable treatment performance with superior energy efficiency.

  • 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.

  • RO-Island HPP 2nd pass
    This is the heart of the SWRO desalination process, where the desalination effect takes place. The treated sea water is fed by means of the high pressure pumps into the RO membranes, obtaining permeate or product water and high pressure brine rejection, whose high pressure energy is recovered by selected Energy Recovery Device.

  • 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 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.
