The SFG series


The SFG series is a range of integrally geared single-stage centrifugal turbo compressors. The semi-open impeller (3D design) is overhung mounted directly onto the high-speed shaft of the gearbox. Due to this design and the resulting minimum mechanical losses, the SFG series offers a very high efficiency and is the preferred solution for demanding duties in clean process gas or air service applications, even in harsh environments. Gas flows up to 250,000 m³/h can be handled. It provides state-of-the-art safety and reliability at lowest lifecycle costs to their owners.

The SFG series is optionally available in a design compliant to API Standard 672 or API Standard 617, Part 1 & 3.

For design pressures up to 50 bar (g) and gas flows up to 200,000 m³/h, the SFG series is also available in a high-pressure design to serve process gas applications and is typically provided with dry gas seals in double or tandem arrangement including a sealing gas panel.
