Hermetic Pump Solutions for Cryogenic Liquid Gases
Hermetically sealed and reliable pump solutions are crucial for handling these media. Low temperatures, high vapour pressure and fluctuating operating conditions place particular demands on pumping technology and plant safety. HERMETIC Canned Motor Pumps enable safe and leak-free operation even under demanding cryogenic process conditions.
Things to Know About LNG and LPG
- LNG (methane)Boiling point: approx. −162 °C
Cryogenic, liquefied natural gas
Significantly reduced transport and storage volume
High demands on materials and leak-tightness - LPG (propane/butane)Liquefaction occurs even at moderate pressures
Typical components: propane and butane
Used in industry, energy supply and transport
High vapour pressure and varying operating conditions
