Franklin Electric 4″ encapsulated submersible motors, built in ISO 9001 certified facilities for outstanding performance in 4″ or larger water wells.
The genuine Franklin Electric 2-wire motor is a split phase, control-box less submersible motor for direct connection to a fused power supply. It incorporates a long-life electronic switch that allows it to run without the aid of external controls or capacitors. Furthermore, it offers a reverse impact torque that can help loosening sand-locked pumps and comes factory-equipped with automatic reset overload and surge protectors.
