BluNet is an experienced China-based cryogenic equipment manufacturer specializing in the design and production of cryogenic pumps for liquefied gas transfer, filling, and distribution systems.
Our low-temperature pump solutions are designed for handling LNG, liquid nitrogen, liquid oxygen, liquid argon, and other cryogenic fluids in industrial gas plants, LNG facilities, and storage systems. These pumps can be integrated with cryogenic storage tanks, vaporizers, filling stations, and complete gas supply systems.
Cryogenic Pumps for Liquefied Gas Transfer
Cryogenic pumps are specialized pumping systems used to transfer liquefied gases from storage vessels to downstream equipment while maintaining stable pressure and flow performance.
Due to the extremely low temperatures of cryogenic fluids, these pumps use low-temperature resistant materials, advanced sealing technology, and thermal protection designs to ensure safe and efficient operation.
