  • Alkylation
    Our process and rotating equipment specialists can help you to optimize performance with highly quality equipment at an excellent performance/cost ratio.

  • Auxiliary applications
    The complex processes performed on a typical FPSO rely on the performance of dozens of pumps handling a variety of liquids under widely varying process conditions.

  • Brine re-injection pump
    The brine re-injection pump re-injects the low enthalpy reject brine back to the geothermal field to renew the available resources.

  • Crude oil pipeline mountainous terrain
    In remote areas, there may not be power available, or, terrain may be so steep that all the pressure rise has to be made in 1 station. Each pump must make the entire head. Pumps are often run in parallel. Hundreds of Sulzer multistage pump performances meet such high pressure requirements.

  • Crude oil pipeline offshore to onshore
    All the pressure rise must be made in the crude shipping pumps on the platform. Salt spray is corrosive and platform movement during storms can affect reliability. Specially packaged Sulzer multistage pumps are used to move crude oil from offshore platforms to onshore storage or pipeline systems.

  • Crude oil pipeline onshore flat terrain
    Power cost is the largest operating cost for crude oil pipelines on flat terrain. Flow rate, viscosity, pipe size, and station spacing all affect pump selection. 2 or 3 mainline pumps are often run in series. Sulzer can help with FEED assistance, rerates to optimize performance and lower power costs.

  • Heat transfer fluid pump
    Heat transfer fluid pump (HTF) pumps circulate thermal oil through the parabolic troughs to heat it up and pump it to the solar steam generator. The main characteristics of the HTF pumps are their high temperature and their double sealing system. Depending on the plant size, HTF pumps can be either double or end suction type.

  • Hydrotreating unit
    Our process technology, column internals and pumps are engineered specifically to optimize your individual unit performance.

  • Liquefied petroleum gas pipelines
    Liquefied Petroleum Gas (LPG) mixtures (ethane, propane, butane) can have vapor pressure up to 40 Bar, specific gravity less than 0.40, and almost no lubricity. Sulzer provides special materials, acoustic studies, and lateral analysis to assure reliable performance with varying flow, speed, and fluid conditions.

  • Refined product pipelines
    Thousands of Sulzer multistage pipeline pumps move diesel fuel, jet fuel, gasoline, and other refined products all over the globe. Sulzer’s global service centers, service and retrofit not only our own pumps, but other pumps and motors as well.

  • Supercritical and compressible fluid pipelines
    For the past 30 years, Sulzer multistage pumps have been used to pump compressible, dense phase ethylene and CO2 at normal and supercritical pressures. Compressible performance prediction, acoustic studies, and, lateral analysis, are all part of service provided by Sulzer engineers for such rigorous applications.
