Franklin Electric offers a complete line of submersible motors for groundwater and other submerged pumping applications. Our 4-inch submersibles (1/3 through 10 hp) feature the industry's widest range of voltage and frequency ratings in both single- and three-phase models. For deeper wells and applications requiring higher flow ratings, Franklin's 6-inch and 8-inch submersibles are available from 5 through 200 hp.
The Franklin 4-inch Super Stainless motor has been the driving force behind residential and light commercial submersible pumps for decades. Designed and patented in 1950 by Franklin's founder, Ed Schaefer, this motor has proven to be the industry’s most trusted residential pump motor.
Franklin offers 4-inch motors in a full line of single- and three-phase voltages, frequencies, and application-specific models. Wherever there is an independent source of clean groundwater, you can find a Franklin motor.
