What type of pump is used for LNG loading pumps?
Thread Content
What type of pump should be used for LNG loading pumps (in front of the loading arm)? Should it be a bag pump, a horizontal centrifugal pump, or some other type of pump?
:Lol, just search on Baidu and there are tons of results.
I’m not sure about the method used for loading LNG onto ships; it involves some special submersible pumps
Why not provide more medium operating condition parameters?
There are submersible pumps and horizontal centrifugal pumps; we use CRYOSTAR’s horizontal centrifugal pumps
Both horizontal centrifugal pumps and submersible pumps can be used, but it is necessary to consider whether loading will be done continuously. If a cold pump is required, in terms of the time needed to achieve cold conditions, submersible pumps are much faster than centrifugal pumps
By submersible pump, do you mean the type with a motor inside the liquid, or a vertical tubular pump?
A low-temperature submersible pump is a high-speed centrifugal liquid pump designed for use in low-temperature environments, with its impeller operating below the liquid surface.
Vertical cartridge type; the cartridge serves as a pump chamber, with submersible pumps located inside it
Either one will work, but submersible pumps are probably the mainstream option these days. But the price is high; those I’ve come across are imported, have a long lifespan, do not require a chill pump, and come with variable frequency control for low-flow circulation when not installed in a vehicle. Sleeve pump must be a cold pump, as it will generate a large amount of BOG.
What is the flushing scheme for the centrifugal pump seal?
