FEATURES
The JGC and JGD are large, medium speed, reciprocating, separable compressors. Since their introduction
in 1994, they have proven to be one of the most cost effective methods of compression for pipeline transmission, power generation, refrigeration, processing, and all other applications requiring large horsepower
drivers and compression capacity.
Serviceability - Entire unit is designed for ease of repair. All components
are readily accessible.
Standardization - Many components are interchangeable throughout the
various lines.
Full Pressure Lubrication - A frame-driven lube oil pump provides
pressurized, cooled oil through a full flow oil filter to all moving parts
in the frame. A divider block distribution system supplies metered
oil to cylinder bores and rod packing. Stainless steel tubing is used
throughout the cylinder lubrication system.
Unloading Devices - Manual head-end variable volume clearance pockets,
pneumatic fixed volume clearance pockets and pneumatic suction
valve unloaders are available on a limited optional basis.
Heavy Duty Crankshaft - Forged steel precision machined with integral
counterweights.

Rugged Crankcase - Heavily ribbed (with spacer bars for stiffening), highstrength cast iron base with removable, lightweight aluminum top cover
and removable end covers for ease of access.
Precision Bearing Shells - Precision-machined, tri-metal main and connecting
rod bearings.

Forged steel JGCconnecting rod

Rugged Crossheads and Guides - Cast iron crosshead guides, external

ribbing and removable side covers. One piece, long life crossheads with
direct full pressure lubrication at top and bottom for minimum wear.
Hardened and ground steel crosshead pins.
Rigid Connecting Rods - Forged steel four bolt, heavy duty H section.
Quiet Auxiliary Drive - Fully enclosed and continuously lubricated chain
drive adjusted by positive positioning eccentric vernier.
Oil and Dust Seal - Foolproof, non-contacting crankshaft oil seal plus
reliable non-wearing dust seal.
Proven Cylinder Design - Non-cooled compressor cylinders with ample
nozzles and large gas passages. Cylinder bodies are ion-nitride hardened
and drilled for indicator ports.

Ductile iron crossheads, babbitted

shoe surface, full-floating crosshead
pin with through-bolt and end caps

High Strength Bolting - Grade 8 bolts or B-7 studs on all pressurized

components. All bolting designed for accessibility.
Efficient Valving - Ariel uses plate-type valves designed for modern speeds
utilizing non-metallic sealing elements as standard. Selected to adhere to
established, low valve velocity standards.
Durable Pistons - Wear-resistant ductile or gray iron with wear bands.
Stout Piston Rods - Short, stiff, precision-ground alloy steel piston rods
with locking crosshead nut. Rolled threads are 1/4 under rod diameter for
easy installation through packing.

Full array of crossheads and nuts for

precise balancing of opposing pistons

More than 35 years ago, Ariel introduced an innovative cylinder design
that eliminated water cooling from the cylinder jacket. This proven
design yields significant advantages over water-cooled cylinders:
higher efficiency
larger gas passages
reduced pressure-drop losses
lower maintenance (no scaling or corrosion)
Ariel is the only manufacturer to use an ion-nitride furnace to increase
surface hardness of all cylinders. This extra step reduces cylinder bore
wear to an absolute minimum. To ensure complete reliability in the
field, Ariel pressure-tests each cylinder to 150% of maximum allowable working pressure (MAWP) during manufacture.

pipeline transmission
