Applications
  • Boiler feed pump (BFP) for biomass waste
    Boiler feed pumps for biomass firing power plants applications are typically small/medium ring section type. Axially split multistage pumps are also available when required. The pump size and the design pressure will depend very much of type and the output of the power plant.

  • Boiler feed water and booster pumps
    Feed water pumps (FWP) pump the feed water from the de-aerator through the HP heaters to the boiler. The major characteristic of FWP is their high differential head.

  • 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 offloading
    Depending on the FPSO design, a booster pump is often required to export crude oil delivered to deck level by the FPSO cargo system.

  • 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.

  • Feed water pump (FWP) for gas-fired
    Feed water pumps (FWP) pump the feed water from the de-aerator through the HP heaters to the boiler. The major characteristic of the FWP is their high differential head. In all sizes of gas-fired combined-cycle power plants, the FWP are horizontal ring section type; occasionally, they could also be barrel or axially split type.

  • Feed water pumps for solar power generation
    Feed water pumps (FWP) pump feed water from the de-aerator through the HP heaters to the solar steam generator. The major characteristic of FWP is their high differential head. The FWP are usually horizontal ring section type, but depending on customer requirements, they can also be barrel or axially split type.

  • Flow assurance (dead oil / hot oil)
    Pumps for flow assurance service, also known as dead oil and hot oil circulation, are critical to maintain oil production in deep cold water. Though usually driven by an electric motor, the Sulzer BB3 and BB5 pumps can be engineered with diesel engine drivers. Along with our reputation for quality and efficiency, our pumps are right for this service.

  • 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.

  • 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.

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

  • 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.

  • RO-island HPP
    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.

  • 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.

  • 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.

  • 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.
