Integrally Geared Centrifugal Compressors API 617 and 672

Integrally geared centrifugal compressors API 617 and 672

BORSIG ZM Compression GmbH has been manufacturing centrifugal compressors for process gases for almost 60 years.

The BORSIG ZM centrifugal compressor series comprises multistage integrally geared centrifugal compressors with up to 8 stages, with steam turbine, gas turbine or electric motor as driver with all auxiliary equipment (turnkey solutions) according to customer’s requirements.

The compressors comply with the corresponding API design standards such as API 617 (chapter 3) and 672 (4th edition). The oil system is designed according to API 614 or manufacturer's standard.

The development is based on the latest research results in fluid mechanics as well as in gear and bearing design.

High efficiency thanks to

  • speed variation
  • cooling between each stage
  • inlet guide vane control
  • axial flow into blades

Benefits compared to reciprocating compressors

  • pulsation-free compressing of the medium
  • oil-free fluid 
  • long uninterupted operation

Power ranges

Discharge pressure:

  • p = (… 150) bara

Capacity/ flow*:

  • V = (... 300.000) m³/h

Power:

  • P = (... 25.000) kW

* related to atmospheric conditions and air

Typical applications

  • Petrochemical industry
  • Refineries
  • Gas treatment
  • Fertilizer industry
  • Power Plant industry
  • Steel industry
