High-Quality LPG Compressors from China Suppliers - Reliable Factory Solutions for Efficient Gas Transfer and Pressurization
Liquefied Petroleum Gas (LPG) Piston Compressor Advantages
01
Large Flow & Cost-Effectiveness
The piston compressor can provide a wide flow range from hundreds to tens of thousands of cubic meters per hour, meeting the needs of large-scale LPG transfer, filling, and process boosting. Its technology is mature, and its procurement and maintenance costs are more economical compared to diaphragm compressors.
02
Mature and Reliable Skid-Mounted Integration
Easily integrated into a fully skid-mounted package including the main unit, inter-stage coolers, gas-liquid separators, lubrication system, and control panel. They adapt to fluctuations in suction pressure and gas flow, ensuring stable discharge pressure.
Key Design Points for LPG Piston Compressors
★
Explosion-Proof & Oil-Free
Motors comply with Ex d IIB T4 rating. Oil-free designs utilize self-lubricating PTFE or carbon composite rings to prevent contamination.
★
Safety Interlocks
Configured with alarms for pressure, temperature, and lubrication failure. Nitrogen buffer packing systems prevent LPG leakage.
★
Material Compatibility
Components like cylinders and valves are resistant to petroleum hydrocarbons. Includes nitrogen purge connections for safety.

Frequently Asked Questions
What is the primary advantage of using a piston compressor for LPG?
Piston compressors offer a large flow range (up to tens of thousands of m³/h) and are more cost-effective in terms of procurement and maintenance compared to diaphragm compressors for large-scale LPG transfer.
Are your LPG compressors suitable for hazardous environments?
Yes, all electrical components and drive motors comply with the Ex d IIB T4 explosion-proof rating, ensuring safe operation in hazardous areas.
Do you offer oil-free lubrication options?
Absolutely. For applications requiring high purity, we provide oil-free designs using self-lubricating piston rings and packing made from PTFE or carbon composite materials.
How do you prevent gas leakage along the piston rod?
We typically recommend a nitrogen buffer packing system. It introduces low-pressure nitrogen to form a barrier, preventing LPG from leaking outward and routing any leaked gas to a safe vent system.
What drive modes are available for the compressors?
Our compressors can be powered by electric motors, diesel engines, or natural gas engines, depending on the site requirements and available energy sources.
Can the compressor adapt to fluctuating inlet pressures?
Yes, through multi-stage compression and cylinder clearance adjustments, our piston compressors are designed to adapt to fluctuations in suction pressure while maintaining stable discharge pressure.
