BMC Integrally Geared Centrifugal Process API 617 Compressor

Reliable and economical, Sundyne API 617 horizontal single stage integrally geared centrifugal 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 BMC (Base Mounted Compressor) product line features horizontal single-stage integrally geared centrifugal designs that process engineers utilize for midstream, hydrocarbon processing and chemical manufacturing applications.  This includes mole sieve dehydration, regeneration of the demethanizer, waste gas, hydrogen recycle and specialty chemical production.  Each compressor is built specifically to meet API Standards compliance and address any project specification requirements to provide pulsation and vibration free operation while delivering oil-free process gas compression with zero emissions.

  • Flows to 3,550 acfm (6,000 AM³/hr)
  • Maximum working pressure 1,450 psi (100 bar)

Built to meet API-617 standards, the BMC will run continuously for 5 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 compliance is available for special services or corrosive environments.

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