Supercritical and compressible fluid pipelines

Pumping at supercritical pressures

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.

Products

  • CP horizontal radially split multistage barrel pump
    CP ISO 13709 / API 610 Type BB5 radially split barrel casing pumps are used in both high-pressure oil production and high-temperature refinery applications.

  • GSG diffuser style barrel pump
    The GSG pump is the least costly form of ISO 13709 / API 610 Type BB5 high-pressure barrel pumps. The GSG back-to-back rotor stack is supplied on low- density services where rotor stability is critical.

  • MSD axially split multistage pump
    The MSD pump has the broadest hydraulic coverage of any BB3 type multistage pump in the market. There are over 10 000 MSD pumps installed in product pipelines, boiler feed, water injection and even nuclear safety-related services around the globe.

  • OHH overhung single stage pumps
    The OHH is our API 610 (ISO 13709) type OH2 overhung, horizontal, centerline mounted, single stage, radially split process pump.

  • OHHL low flow high head pumps
    The OHHL is our API 610 (ISO 13709) type OH2 low-flow horizontal overhung process pump. It covers the low-flow end of the OHH range map.

  • SJD API vertically suspended process pump
    The SJD (API) are ISO 13709/API 610 Type VS1 and VS6 pumps whose design has evolved from many years of experience. They utilize Sulzer's low Net Positive Suction Head (NPSH) 1st stage, followed by unique high head per stage series hydraulics, to minimize the number of stages required.
