Abstract

A centrifugal pump having an impeller (38) which is associated with a motor and a drive shaft (16,14) and that is enclosed within a housing (28). The housing (28) is mounted in surrounding, spaced and non-contacting relationship, with respect to the impeller (38) and drive shaft (14) contains fluid inlet (26,26') through which fluids are directed by the impeller (28) to an outlet from the housing (28). Also provided is a pump which operates from remote locations.
