Features
The JGR and JGJ are medium-size separable reciprocating compressors, well-suited for gas gathering on moderate-sized
wells. These models are particularly effective for fuel-boosting applications and are packager-friendly, pairing easily with
electric motors and natural gas engines.
Full Pressure Lubrication: A frame-driven lube oil pump provides cooled oil through a
full-flow oil filter to all moving parts in the frame. A divider-block system supplies metered
oil to cylinder bores and rod packings.
Rigid Conrod with
bronze bushing
High-Strength Bolting: Durable Grade 8 bolting on all loaded joints combined with
specially designed fatigue-fighting bolts on all valve caps ensure ultimate holding strength.
Rigid Connecting Rods: The JGR/JGJ compressors feature durable connecting rods
manufactured from forged steel with 4 bolts and a heavy-duty I section.
Rugged Crossheads: One-piece, long-life crossheads with hardened, ground steel
crosshead pins and direct, full-pressure lubrication at the top and bottom for minimum
wear.
Rugged one-piece
Crosshead
Innovative Cylinders: Ariels single and double-acting non-cooled cylinders eliminate the
cost and maintenance associated with water cooling.
Durable Pistons and Rods: JGR/JGJ compressors feature wear-resistant ductile or gray
iron pistons, and precision-ground alloy steel piston rods with locking crosshead nuts.
Rolled threads are 1/4 under rod diameter for easy installation.
Precision Bearing Shells: Every Ariel compressor features precision-machined tri-metal
main and connecting rod bearings.
Versatile Unloading Devices: Ariel offers manual, head-end variable volume clearance
pockets on most cylinders. Pneumatic suction valve un-loaders are available on a limited
basis.
Application-Specifc
Efficient Valves
Efficient Valving: Plate-type valves are designed for modern speeds, utilizing nonmetallic sealing elements as standard. Valves are selected to comply with established lowvalve velocity standards.
Heavy-Duty Crankshafts: The JGR/JGJ compressors feature forged steel, precisionmachined crankshafts with integral counter-weights manufactured by Ariel Corporation.

piston rod design
High-Efficiency Spin-on Oil Filters: Ariel JGR/JGJ compressors feature high-efficiency
non-bypassing spin-on oil filters rated at 5 micron nominal and 17 micron absolute.
Rugged Crankcases: Ariel crankcases are designed for long service life and ease of access
during maintenance. Our crankcases feature a heavily-ribbed, high-strength, cast iron base
with a removable, lightweight aluminum top cover.
