Source
This close-coupled pump AC motor is designed for demanding pump applications requiring high efficiency and reliable performance. Featuring a totally enclosed fan-cooled (TEFC) enclosure and face/base mounting, it is suitable for horizontal installations in environments where protection from dust and moisture is essential. The motor delivers 7-1/2 HP output, operates on three-phase power, and is inverter rated for variable speed applications. Its steel frame construction and ball bearings ensure durability, while the JM threaded shaft design supports direct coupling to pumps. Commonly used in industrial and commercial pumping systems.
