ABSTRACT:
A jacket of a submersible pump motor is provided with an internal partition wall to provide chambers through which dry air may be circulated in the event that cooling fluid into the pump runs out. When the pump turns, its impeller forces the air to circulate around the partition wall and carry heat from hot areas of the jacket adjacent to the pump motor to be dissipated through cool outer areas of the jacket.
