ABSTRACT:
A submersible motor enclosure and method of operating the same, having particular utility for enclosing a motor used to power a screen rake in a waste water treatment plant. The enclosure has a closed end and an open end coverable by a cover plate. A pressure source is in communication with the housing interior to pressurize the interior and to resist the migration of water into the housing. A discharge port may be included to collect and discharge any water that enters or condenses in the housing. An alternate embodiment utilizes a vacuum source in communication with the discharge port instead of the pressure source in communication with the housing interior.
