Reciprocating compressor JGJ

reciprocating pistonnatural gaselectric

Overview
The Ariel JGJ is a separable, medium‑frame reciprocating compressor designed for gas gathering and fuel‑gas boosting on moderate‑capacity wells. It delivers compact, high‑speed performance with a short stroke and high rod load relative to its footprint.

Applications

• Fuel‑gas boosting
• Gas gathering at well sites
• Installations driven by electric motors or natural‑gas engines

Product Features

• Efficient valves: Plate‑type valves configured for modern operating speeds, standard with non‑metallic sealing elements and selected to minimize valve velocity.
• Precision bearing shells: Tri‑metal main and connecting‑rod bearings machined to tight tolerances for consistent service life.
• Rigid connecting rods: Forged‑steel rods with four bolts and heavy‑duty I‑section for high rod‑load capability.

Materials

• Gray iron crankcase: Forged‑steel crankshaft, gray‑iron crosshead guide, bronze thrust bearing, tri‑metal main bearing.
• Ductile iron crosshead: Alloy‑steel crosshead pin.
• Forged steel connecting rod: Bronze crosshead pin bushing, tri‑metal connecting‑rod bearing, grade‑8 stress bolts.

Cylinders and configuration
Ariel offers versatile cylinder designs that cover wide pressure ranges and can be combined in numerous arrangements to meet specific volume and pressure requirements. Ariel 7 Performance Software is used to model and select cylinder and compressor configurations for field applications.
