LNG submersible pump
Thread Content
Regarding the current foreign brands of LNG submersible pumps – NIKKISO, EBARA, JC.Carter, Cryosyar, ACD – what is their quality ranking? Which one is the best? And what are their prices?
It mainly depends on whether the submersible pump needed by the poster is to be used in an environment such as a large receiving station or a gas filling station. For gas filling stations (small pumps), ACD CRYOSTAR is generally used; currently, several domestic manufacturers also produce high-quality pumps. As for the large pumps used in receiving stations and liquefaction plants, they are basically from two Japanese brands at present. . . . .
The prices aren’t cheap; consider domestic options instead, such as Dalian Leo and Dalian Deep Blue!
You mean that large LNG submersible pumps mainly rely on imports as domestic production is not feasible, while smaller submersible pumps can be manufactured domestically, right?
I have seen several LNG plants overseas operated by an international engineering company; they were designed by Americans, and all of them use EBARA pumps, which are purchased exclusively from that company
Do you have JC.Carter’s contact information?
LNG submersible pumps, whether domestic or imported, require an environment that maintains low temperatures for proper operation. Chengdu Hengli specializes in the manufacturing of vacuum pump chambers and vacuum-insulated pipelines for transporting low-temperature liquids; its products feature a rational design and excellent performance.
Among large-tank submersible liquid pumps, those with the best performance and strongest technical capabilities are likely NIKKISO and EBARA; JC.Carter has been acquired by NIKKISO. The French company Cryosyar also offers such pumps, and these pumps have an LNG flow rate of 200–2000 m3/h, with very high prices. In China, only pumps with low flow rates can be used for gas stations.
