Submersible / Immersible Motors

Offering a solution for both wet and dry pit applications, the Baldor-Reliance® Submersible motors provide a proven solution for municipal and industrial wastewater operations as well as slurry pumps, aerators and mixers.

WET pit motors use the effluent for cooling and can run 15 minutes in air. DRY pit motors are sized to run continuously in air or submerged even at a depth of 200ft.

The Baldor-Reliance® Immersible motors are designed for use where the possibility of flooding exists. This motor features totally enclosed, blower-cooled enclosures and are designed with a unique sealing system. The system allows reliable operation for a period of two weeks while submerged under a maximum depth of thirty feet of water.
