The SF Series

The SF series is a range of single-stage centrifugal turbo compressors with an overhung, semi-open impeller (3D design), supported by a separate bearing pedestal, direct driven or provided with a separate gearbox. With this design, featuring highest rigidity and optimised rotordynamic behaviour, the SF series serves the most demanding duties in its industries - like compression of corrosive, erosive and sticky gases and suitable for installation in harsh environments. Gas flows up to 600,000 m³/h can be handled. It sets the benchmark for safety and reliability, at lowest lifecycle costs, in favour of their owners.

With package weights of over 50 tons, this machine is the most heavy duty equipment of its kind on the market.

The SF series is optionally available in a design compliant to API Standard 617, Part 1 & 2.

For design pressures up to 50 bar (g) and gas flows up to 200,000 m³/h, the SF 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.
