Abstract
A hermetic pump includes a housing having a bore, an inlet, and an outlet for channeling a fluid therethrough. A shaft is disposed coaxially in the bore, and includes a journal and an impeller spaced apart therefrom. The shaft is hermetically rotated to pump the fluid through the bore from the impeller and around the journal for developing a hydrodynamic journal bearing. In one embodiment, the pump may be used in a closed loop cooling circuit.
