Cryogenic Pumps
Tips & Advice to help you make your decision on Cryogenic Pumps
Cryogenic pumps are special types of centrifugal pumps that are used to pump extremely low temperature liquids. Handling these low temperature liquids requires the use of materials that are resilient enough to withstand such extremes in temperature. Regular or substandard materials will readily fail in these environments.
These pumps have the same pump mechanisms as other centrifugal pumps but are made from more durable materials. They are commonly used in the transport of low temperature liquids such as liquid nitrogen gas (LNG), liquid nitrogen, liquid oxygen and liquid helium. Many of its applications are found in marine transport, manufacturing, industrial and laboratory settings.
Manufacturers of cryogenic pumps must give special attention in the selection of materials to be used in assembling these pumps. Also, clearances must be adjusted to account for the differences in thermal expansion and contraction of the materials in low temperatures. Manufacturers may also consider the use of special elastomers to accommodate low temperatures. Finally, in order to extend the life of cryogenic pumps, manufacturers must take extra care to avoid cavitation as most cryogenic fluids boil in just the slightest variations in temperatures.

Cryogenic Pumps
Find cryogenic pump companies to meet your business needsBy Patricia Flinsch-Rodriguez, Freelance writer Self-Employed Cryogenics are being used in many different industries such as: food processing, aerospace, microbiology, pharmaceutical, surgical, electronics and metalworking. Cryogenics require extremely low temperatures to liquefy the gas and as a result specialty equipment must be used. Industrial cryogenic pumps must be used to move liquefied gas at cryogenic temperatures. Cryogenic pump design must take into consideration the extreme temperature under which it will be used so that it will continue to function properly.
Some determining price factors to think about when purchasing industrial cryogenic pumps are how the pumps will be used and how often the processing will be needed.
1. Will the cryo pumps be used in a high or low flow continuous operation?
2. Will the cryo pumps be used in a high or flow intermittent operation?
3. Will single or multi-stage cryo pumps be needed?
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.
Try:
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.
Try:
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.
Try:
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.
- There are lots of options when attempting to ascertain which high pressure cryogenic pumps you should buy. Consider hiring a cryogenic consulting company that can evaluate your existing processes and can offer you new solutions.
