Description

This invention relates to centrifugal pumps and particularly to pumps designed for handling low temperature liquids, such as liquid air, at or near their very low boiling points. In pumps designed for such purposes it is obviously necessary to reduce all heat losses to a minimum. It is the general object of my present invention to provide a construction in a centrifugal pump by which the friction of solid bodies in running contact is entirely avoided. More specifically, I provide a construction by which a liquid is rendered effective by centrifugal force to serve as packing for the pump and shaft, all other packing being avoided.
