Reducing Life-Cycle Costs For Pumps Handling Cryogenic Fluids
MetadataShow full item record
Advancements in the science of sealing technology have had a dramatic effect in increasing equipment reliability and reducing the cost of equipment ownership. One such area of success has been the pumping cryogenic fluids that are stored near atmospheric pressure and pumped near their normal boiling points. The most common cryogenic fluids used in industry are argon, nitrogen, and oxygen. These fluids are delivered over the road in tank trucks to industrial users and hospitals. Each truck uses a single-stage centrifugal pump driven by a hydraulic motor to move these liquids from the truck to storage tanks. This paper reviews the development of the technology to increase equipment reliability. Reduced life-cycle cost analysis and savings are presented.
