Abstract

A liquid He transfer system with overall transfer losses < 2% is described. Energy and running time savings for Heliquefiction up to 30% are achieved in comparison with conventional transfer using a pressurized liq. Hestorage tank. The main components of the system are a high reliable, completely magnetic suspended centrifugal pump submerged in the liquid and a double transfer line allowing cold gas exchange between transport vessel and storage tank. Filling rates up to 1500 L/h and more are possible. Constructional and performance date of the system are reported.
