Franklin , 4” Rewindable Oil-Filled motors of the thay are rewindable motors and operate in wells with water not over 30 °C and a pH ranging between 6.5 e 8.0. The filling liquid is a dielectric fluid, known as white oil, approved by the FDA and other international pharmacological institutes. The coupling dimensions and flange comply with the NEMA standard, as these submersible motors are specifically designed to operate coupled with submersible deep well pumps with the same coupling dimensions.
