Cryogenic centrifugal pumps
Centrifugal pumps are among the most reliable pumps in the world. They are designed for cryogenic applications including liquefied natural gas (LNG), liquid hydrogen (LH2), marine, and industrial gas liquefaction processes such as air separation or carbon capture. The Alfa Laval Cryomec® range ensures safe and efficient fluid transfer across various industrial processes, handling extremely low temperatures.
The benefits of Cryogenic centrifugal pumps
- Reliable performance
- Low cost
- Available in vertical and horizontal configurations
The Cryomec® range of cryogenic centrifugal pumps is perfect for Liquefied Natural Gas (LNG), Liquid Oxygen (LOX), Liquid Nitrogen (LIN), Liquid Argon (LAR), Liquid Carbon Dioxide (LCO2), Liquid Nitrous Oxide (LN2O), and Liquid Hydrogen (LH2).
World leading expertise in cryogenic technology
With 16,000 hours of duty guaranteed without maintenance, the Cryomec® brand is recognized for its experience in cryogenics.
- Labyrinth seal technology
- Cryomec® cartridge technology for easy maintenance (multi-stage pump)
- Slow-roll and cold stand-by
- Rotating Supercharger (SC) for single stage with low NPSH (down to almost zero)
How the Cryomec® centrifugal pumps technology works
The unique design maximizes seal system safety and efficiency, eliminating the risk of unwanted leaks into the motor chamber and improving efficient fluid transfer at very low temperatures. This makes them the perfect partner in demanding cryogenic applications.
