Choose single or multi-stage cryogenic oxygen pumps

Cryo pumps are manufactured as either a single-stage or a multi-stage pump. Multi-stage units are primarily used for removing all gases from a vacuum chamber. Single-stage pumps are used to condense gases with low vapor pressures.

I recommend: Lawrence Pumps specializes in the manufacture of multi-stage pumps. Cryostar USA West and SHI Cryogenics manufacture single-stage and multi-stage cryogenic process pumps.

Set up accounts with multiple cryogenic pump suppliers

Having multiple suppliers for your cryogenic pump needs makes good business sense. In today's uncertain economies, businesses can shut down overnight and you do not wish to be left in the lurch if the only supplier you use suddenly goes out of business. Arrange payment terms with several cryo pump suppliers so that you can choose which supplier to use when the need arises.

I recommend: Stainless steel cryogenic pumps can be purchased from Teikoku USA/Chempump. Buy a cryogenic vacuum pump from PHPK Technologies. Barber-Nichols specializes in manufacturing cryo vacuum pumps.

Secure the services of a repair company for your high pressure cryogenic liquid pumps

Once you have found your cryogenic pump suppliers, make sure you locate a business that will service your high pressure cryogenic pumps in the event of an equipment failure. Look for a business that does emergency repairs as well as one that has a same day pump exchange so that you can get back up and running quickly.

I recommend: Austin Scientific is one of the Cryogenic Pump Manufacturers that also repairs all brands of cryo pumps and offer fully warranted refurbishment. FMG Enterprises offers emergency service within hours and a same day pump exchange. Cryogenic Industries has service and repair centers throughout the United States.
