Sulzer helicoaxial multiphase pumps enable boosting of the oil/gas/water mixture from producing wells, without separating the gas from the liquids. They are successfully deployed onshore, offshore and subsea, in a variety of environments and climates.
Main benefits
- Full pull out cartridge construction reducing downtime and allowing retrofit as field conditions change
- Sand tolerant thanks dedicated abrasion resistant material, coating and large clearances
- High pressure boost thanks Sulzer extensive balance drum experience
- Horizontal or vertical configurations to fit the application
- Subsea qualification testing and JIP projects welcomed
- Variety of sizes available from 1 to 10 MW to suit the field development, production and decline
Main applications
- Multiphase pipeline boosting
- Pipeline debottlenecking
- Flaring reduction
- Re-activation of dead wells
Main design features
- Helicoaxial stages designed for operation from GVF 0 to 100%
- Stage design change to compensate for gas compression through the pump
- Full pull out cartridge construction
- Sulzer pressure boundary design experience to 1000 bar
- Variety of performances: single-phase, multiphase or hybrid
- Variety of driver types: Motor, GT, high-speed permanent magnet motor, etc.
