L-CNG Plunger Pump


The L-CNG Plunger Pump sled is one of the core equipment of L-CNG refueling stations, used to achieve LNG liquid pressurization and provide high vaporization pressure.
According to their configuration, they can be divided into single pump sled, double pump sled, triple pump sled, and multi pump sled.
According to their pipeline insulation methods, they can be divided into polyurethane foam insulation and vacuum tube insulation pumps.
Advantages
- It realizes automatic control of solenoid valves for all kinds of pipelines on the pump sled.
- It boosts low-pressure liquid LNG from 0.5MPa up to 20–25MPa to meet high-pressure delivery requirements.
- The whole pump sled supports both manual and automatic control modes for flexible operation selection.
- The two pumps work independently without mutual interference.
- The dual pumps can operate separately according to working demands.
- The dual pumps can run simultaneously for higher processing capacity.
Application
L-CNG Plunger Pump is applied:
- L-CNG refueling stations for pressurizing low-pressure LNG to high pressure for vehicle gas filling
- Natural gas distribution stations for pressure boosting of liquefied natural gas
- Gas energy projects requiring LNG pressurization and vaporization treatment
- Skid-mounted gas supply systems for industrial parks
- Mobile gas refueling and gas supply projects
- LNG storage and transfer stations for medium pressure regulation
