Sundyne LMC Vertical Integrally Geared Process Gas Compressors

Reliable and economical, the original fit-for-purpose Sundyne vertical integrally geared compressor

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 LMC – Line Mounted Vertical Compressor line features single-stage integrally geared centrifugal designs that process engineers utilize for fit-for-purpose 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 850 acfm (1,450 AM³/hr)
  • Maximum working pressure 1,440 psi (100 bar)

NACE compliant Sundyne compressors do not rust or corrode.  Each unit is engineered in accordance with industry standards, and is designed to run continuously for 5 years without the need for costly maintenance or over-hauls.

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.

O-rings

As Required

  1. “O” build temperature range 0° to -240° F. Pressure capability is reduced due to strain hardened pump case studs. Contact Application Engineering.
  2. See Sundyne Corporation exceptions/clarifications to API 610, 11th edition for material requirements of pump parts.
  3. Impeller is upgraded to 316SS. A seal gland is not required because the seals mount in the seal housing. O-rings are used instead of a case gasket.
  4. A seal gland is not required because the seals mount in the seal housing. The pump shaft is AISI 4140 because it is not exposed to the fluid. O-rings are used instead of a case gasket.
