Domestic LNG cryopumps
Thread Content
Dear marine friends, are there any reliable LNG cryopump suppliers in China? The company has 2 low-temperature pumps of the ACD type, and the management plans to purchase another domestic pump as a backup. It seems that currently only Dalian Deep Blue offers LNG cryopumps; I’m not sure if any other companies have used them and whether they operate reliably
What size pump are you using? Is it used for inflation, pressurization, or loading? If it’s a gas-filled type, there are also Hangzhou Xinya, Huzhou Mitsui, Sichuan Air Separation, etc. As for the pressurized type, well, it’s better to choose imported ones in that case. When it comes to loading onto a vehicle, the price of imported products is not very different from that of domestic ones, so it’s better to use imported products directly.
I know Mitsui is pretty good; I have their contact information

I’m using a Dalian Deep Blue model here; it’s a bit inferior to imported ones – it vibrates quite a lot, but it still works

I work with equipment for entire systems, and I mainly consider the amount of fluid you need to add. If that amount is high, both domestic and imported pumps require annual maintenance; imported pumps cost 2-3 times more. We have used domestic pumps before, and you can message me privately
