Typical Construction Elliott single stage compressors meet API specifications for demanding applications. Components are carefully selected in accordance with design specifications. The casing is center-line supported to maintain correct alignment under variable ambient and operating temperatures. Casing nozzles are designed to meet API specifications, incorporating a minimum 1.85 safety factor on allowable forces and moments. The casing is hydro-tested at 1.5 times the design pressure. Elliott high-efficiency impellers have an enclosed backward lean design.

Impeller Seal (for enclosed impeller) To minimize internal recirculation, a variety of impeller seals are available. Special consideration is given to gases which contain particles. Shaft The shaft is machined from a forging and subjected to ultrasonic and magnetic particle inspections. The thrust collar is replaceable. Shaft Seals Elliott offers a wide variety of seal options including: Dry gas seals Iso carbon / Oil film seals Labyrinth seals Bearing Housing The bearing housing is separate from the compressor casing and is horizontally split for the oil-lubricated design. The bearings can be...
