pumps for low temperature service
pumps for low temperature service
(OP)
Dear All,
I am currently part way through a project into the use of mechanical seals for use in low temperature and cryogenic service. Whilst I am reasonably ok with the seal side of things, I am struggling to find the "typical" pump types and manufacturers used for these duties.
Who are the market leaders for cryogenic pumps, what seals do they use, what is the orientation etc.
Could anyone offer assistance, links etc.
Many thanks

In Europe, Cryostar is the biggest name. They also sell pumps internationally. Both recip and centrifugal. http://www.cryostar.com/
In all fairness, Barber Nichols http://www.barber-nichols.com/ is another cryogenic pump manufacturer in the US that makes pumps primarily on a special order basis. These are typically low pressure centrifugals that are often hermetically sealed and made for a very specific purpose.
Some of the industrial gas companies also make their own pumps, Air Products and Chemicals being perhaps the most noteworthy. These pumps are not generally for sale though, they are leased. You have to purchase their product to get their pump. For higher pressures, they are typcially the best available.
