Datasheet
Product overview
Power: Selected driver / site conditions · Pressure: Duty-specific gas selection · Flow: Agreed capacity reference required
Gunai explicitly titles its two 8M125 product entries as reciprocating piston compressors. It describes cylinders, pistons, crankshaft, connecting rods and gas valves as the compression mechanism and supplies two original installed-machine views. These establish the product reference and mechanism, not an operating rating or an automatic approval for every gas or industry named in general marketing text.
The current pages do not provide a duty-specific pressure, flow, motor-power, speed, stage or dimension table. Request the actual model suffix and datasheet with gas composition and impurities, suction pressure/temperature variation, discharge, flow reference, operating modes and driver/site conditions. Do not treat the 125 in the name as pressure or motor power, and do not reuse historic news figures as a current machine guarantee.
For a new package, agree cylinder/material and gas-side lubrication choices, packing/leakage and vent arrangements, cooling, valve selection, control/protection interfaces, pulsation/vibration responsibilities and mechanical/performance tests. Ask for current foundation, lifting, maintenance and shipping drawings plus offered auxiliaries and commissioning scope. For installed-base maintenance, identify serials, cylinder/packing/valve part numbers and drawing revisions before ordering replacements. The original 8M125 photograph is a real installed assembly from the manufacturer page; its specific gas, numeric duty and customer identity are not stated.

| Piston compressor manufacturers in China | Piston packages in China run from workshop portables to API-style process recips. Those are not one RFQ. Write pressure stages and whether the air must be oil-free. |
