Gunai 6M50 reciprocating process-compressor reference — Gunai Heavy Industry (Suzhou) — Taicang

Datasheet

Product overview

Power: Selected driver duty required · Pressure: Selected gas inlet / outlet duty · Flow: Capacity and volume basis required

Gunai publishes two 6M50 compressor pages with original installed-machine photographs. The images show the reciprocating arrangement; the centrifugal compressor is a separate catalog entry. Independent historical patent CN204827865U also describes piston rods and oil-scraper components on a Gunai 6M50-305/320 example. That corroborates the reciprocating mechanism without turning that historical installation into the rating of every offered machine.

The 6M50 product text makes general statements about efficiency, control and maintenance but does not give a numerical model-duty table. Retain the actual model reference and request the selected gas composition, suction/discharge conditions, capacity and volume basis, driver power, speed, stages and lubrication. Do not decode a pressure, capacity or motor rating from 6M50 or copy a specification from another manufacturer's similarly named machine.

For an existing unit, provide its full nameplate/serial information, frame and cylinder identity, current duty and the components involved. Confirm drawing revisions and the actual material, clearance and valve/packing specification before buying replacements or modifying the duty. For a new package, establish gas containment, cooling, controls, pulsation/vibration study and foundation boundaries plus performance/mechanical acceptance. The original installed-machine image is associated with the 6M50 page; its process gas, numeric duty and final order scope are not identified.
