Sundyne LF 2000 API 617 / ISO 10439 Base Mounted Integrally Geared Multi-Stage Process Gas Compressors

Sundyne LF 2000 Compressor

Reliable and economical, Sundyne API 617 / ISO 10439 integrally geared multi-stage compressors

Process gas compressors are the heart of the process. Their reliability directly impacts the productivity and the efficiency of the midstream, hydrocarbon processing or chemical plant.

The Sundyne LF 2000, commonly referred to as a Pinnacle is a compressor that can be outfitted to meet exacting API and ISO standards.  The LF 2000 features from one to six stages of centrifugal compressors on a single gearbox. These designs save valuable space and reduces energy costs. Process engineers utilize these multi-stage compressors for midstream, hydrocarbon processing and chemical manufacturing applica­tions including mole sieve dehydration, regeneration of the demethanizer, waste gas, hydrogen recycle and specialty chemical production.  Each compressor is custom built to provide pulsa­tion- and vibration-free operation, and to deliver oil-free process gas with zero emissions.

  • Flows to 10,000 acfm (17,000 AM³/hr)
  • Maximum working pressure 5,000 psi (350 bar)

Built to meet exacting API-617 / ISO 10439 standards, the LF 2000 will run continuously for 5 to 7 years without costly maintenance or an overhaul. These horizontally configured compressors are ideal for skid packaging — due to their unique modular baseplate — and are easy to install into any process environment. Packaging and instrumentation are customizable to meet your needs and specifications. NACE compliant Sundyne compressors do not rust or corrode.

Sundyne gas compressors provide the performance envelope, the feature set, the reliability ratings and the uncompromising efficiency needed to address the Best Efficiency Point (BEP) for any process gas application in the most demanding environments.


  • Mole sieve dehydration
  • Regeneration of the demethanizer
  • Waste gas
