Applications
  • Hydraulic power recovery turbine
    Many industries aim to reduce their ecological footprint by minimizing energy consumption. Sulzer Hydraulic Power Recovery Reaction Turbines can be used to capture lost energy.

  • Seawater treatment
    With enhanced oil recovery methods, often prior to injection sea water needs to be treated to remove or reduce salt content. Sulzer’s pumps achieve this by delivering sea water to the SRU / SWRO membrane racks.
