Liquid Helium Pumps.
Abstract
The report summarizes studies of pump characteristics and performance in supercritical, normally boiling, and superfluid helium, and also presents results on a sruvey of commercially available pumps for helium service. Experimental measurements were made on a centrifugal pump which produced a maximum head of about 15 meters, and a maximum flow of about 0.00025 cu m/s. Performance agreed approximately with classical affinity laws, but cavitation appeared to provide less of a performance limitation than expected. The survey turned up several pumps which have been used in helium, though relevant performance data is lacking. (Author)
