Orion-D - ARIEL JGK & JGT GAS COMPRESSOR

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), high strength 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.
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.
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. Available 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.
