SJT vertical turbine pump

An industry-favorite vertical turbine pump

SJT pumps are typically used whenever a liquid needs to be pumped upward from ground water tables (deep well pumps), manmade underground storage (caverns) or open bodies of liquid. Fully updated hydraulics and mechanical designs make the SJT highly efficient, cost- effective, and low-maintenance.

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.

  • 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.

  • 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.

  • 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.

  • Seawater lift
    Sulzer builds both lineshaft and submersible motor vertical seawater lift pumps. Sulzer SMHv and SMDv pumps are vertical shaft in BB1 casing.

  • Water intake
    Water supply is vital for our daily life. To abstract the water at the source, be it the sea, river, lake or dam, water intake pumps are needed. Sulzer offers a range of pumps that are specially engineered for such applications.

  • 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.
