Gas compressor unit JGM

pistonmulti-stage

Overview
The Ariel JGM and JGP are small-frame reciprocating gas compressors suited for gas gathering, gas lift and CNG applications. They are designed to couple with a wide range of high-speed engines and accommodate up to 170 BHP. Using up to 4 stages of compression and a broad cylinder library, the JGM and JGP provide multiple configuration options within a compact footprint.

Applications

• Gas gathering
• Gas lift
• CNG filling and small-line compressor duties

Product Features

• Compatibility with a wide range of high-speed engines
• Support for up to 4 compression stages via an extensive cylinder library
• Versatile cylinder configurations to match required flow and discharge pressure
• Unloading options: manual head-end variable volume clearance pockets (VVCP) on most cylinders; limited availability of pneumatic suction valve unloaders
• High-efficiency, non-bypassing spin-on oil filters (5-micron nominal, 17-micron absolute)

Materials

• Gray iron crankcase: forged steel crankshaft, gray iron crosshead guide, tri-metal main bearing
• Gray iron crosshead: alloy steel crosshead pin
• Ductile connecting rod: bronze crosshead pin bushing, tri-metal connecting rod bearing, grade 8 stress bolts
