ABSTRACT:
Cooling apparatus for removing heat generated by friction between machine parts located within a liquid confining enclosure, for example, a seal surrounding the drive shaft of a motor driven pump used for below-ground pumping of sewage, the apparatus comprising a baffled chamber of novel construction which may be mounted on the pump motor housing and cooperates with a tubular heat exchanger, for automatic circulation, in closed circuit, of hot cooling liquid from the seal to the chamber, where it circulates in an orbital motion by virtue of the baffle arrangement, then passes to the tubular heat exchanger, and from there to the seal to cool it.
