Cornell Immersible Pumps
The immersible motor can operate in flooded conditions, submerged up to 30 feet, for up to a two-week period. The proven concept combines safety of a submersible with the ease of maintenance of an off-the shelf motor. The basic design incorporates a premium-efficiency, inverter-duty TECB (totally enclosed, blower-cooled) motor. If the motor becomes submerged, the blower shuts down without affecting the main motor. While submerged, the media cools the motor just like a true submersible. A special conduit box is used to prevent water leakage into the motor. The motor is designed to prevent infiltration of water along the shaft and into the motor using a patented hydro-seal design.
