LNG Booster Skid – High-Pressure Cryogenic Pumping System
DSW LNG Booster Skids are skid-mounted cryogenic pumping systems designed to efficiently boost liquefied natural gas (LNG) into vaporizers, transforming it into compressed gas for storage in tanks or cylinders. These high-pressure booster systems are ideal for LNG refueling stations, distribution terminals, and CNG cylinder filling operations across Europe.
Our skid-mounted LNG booster systems provide safe, reliable, and high-performance solutions where incoming pipeline pressure is insufficient. Each unit is housed in a robust, modular enclosure, ensuring easy access, maintenance, and operation. DSW offers customised LNG booster skids to meet diverse flow rate requirements and site-specific specifications.
Main Feature:
The LNG Double Boost Pump Skid is designed to efficiently dispense LNG at high flow rates, making it ideal for fueling applications.
Efficiency Flowrate: Each pump in the skid can deliver 40 gallons of liquefied natural gas (LNG) per minute (gpm), ensuring quick refuelling.
Safety and Accuracy: It’s reliable, safe, and accurate, meeting industry standards.
Booster systems are configured in front of the inlet dryer in a typical site configuration.
Easy Maintenance： The control system online monitors the temperature and pressure of LNG and gas turbines or engines to prevent overheating, freezing, or overloading.

- LNG refueling stations for automobiles and buses
- CNG long-tube trailer filling stations
- CNG cylinder and tank filling operations
- Industrial LNG transfer and distribution
DSW supplies a range of skid-mounted cryogenic pumps including: transfer pump skids, high-pressure pump skids, and pressure-boosting pump skids. These systems provide significant economic benefits by minimising BOG waste and maximising operational efficiency.
Comparison of advantages(China LNG dispenser and imported pump)
This table highlights the advantages of DSW’s L-CNG high-pressure cryogenic pump compared with imported submersible pumps, showing operational efficiency, safety, and reliability benefits.
| Item | Chinese Cryogenic Pump | Imported Submersible Pump | Application | Advantage |
|---|---|---|---|---|
| 1 | Low inlet pressure (~0.02 Mpa) | High inlet pressure (>0.3 Mpa) | Atmospheric storage tanks | Reduces BOG loss, no need for pressure reduction, saves ~$4400/month |
| 2 | Auto high-pressure start (19–20 Mpa) | Requires lower pressure start (<10 Mpa) | L-CNG car filling stations | Saves $2200–3000/month with high-volume refueling |
| 3 | Low vibration operation | High vibration operation | L-CNG car filling stations | Prevents piping leaks and operational issues |
| 4 | Return air vent at top, works at low liquid level | Return air vent at middle | Low-level storage tank operation | Avoids stopping station during low supply |
| 5 | Back end sealed with liquid + gas seals (16 total) | Only 8 gas seals, shorter lifespan, prone to leakage | Continuous operation at L-CNG stations | Ensures long-term leak-free operation |
| 6 | High operational efficiency and output | Low efficiency and output | Peak refueling periods | Clear advantage during high-demand operations |
| 7 | Transmission box sealed with oil cup, no leakage | Ventilation cap design, prone to leakage | L-CNG stations | Ensures long-term operation, avoids oil leakage |
