Applications
  • Auxiliary services
    In each desalination plant there is a number of pumps providing auxiliary services at the different stages: filter backwash, membrane flushing, membrane cleaning, etc. Due to lower head and flow requirements, typically theses auxiliary services will require end suction, single stage pumps.

  • Chemical recovery
    Sulzer’s extensive product portfolio is designed to meet the most demanding hydraulic coverage requirements in your evaporation, recovery boiler, and white liquor preparation processes.

  • Chemicals for Pulp Paper and Board
    Tailored designs, features and material selections to meet the most demanding pumping, mixing, and agitation challenges in the production and preparation of chemicals, tall oil production, and lignin processing.

  • Coating and finishing
    A wide selection of highly efficient and reliable pumps and agitators for your pigment handling and color coating processes.

  • Industrial water and effluent treatment
    Sulzer has a deep knowledge in wastewater treatment, and with our wide product portfolio we can now offer energy-efficient and reliable solutions for your water collection, neutralization, flocculation, sedimentation, cooling, aeration, sludge storage, digestion, and dewatering processes.

  • Mechanical pulp line
    Sulzer’s ideal product portfolio for challenging pumping, agitation, and mixing operations in refining, grinding, CTMP, screening, reject handling, and bleaching processes.

  • 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.

  • 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.

  • Recycled fiber line
    Energy-efficient products with low life cycle costs and a lighter environmental footprint for your pulping, screening & cleaning, flotation, washing, and bleaching processes.

  • 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 supply
    Meeting today’s challenges and high requirements within water intake, sedimentation, sludge treatment, fine screening, and water distribution processes.

  • Wood yard
    Energy-efficient products with low life cycle costs and a lighter environmental footprint for your debarking, washing, chipping, screening, and bark and waste streams handling processes.
