4 inch Franklin Electric E-tech Coverco Rewindable Submersible Motors
Franklin Electric Coverco 4" submersible motors of the NBS4 series 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.
The motors can be powered with single-phase and three-phase power supply. The single-phase line ranges between 0.37 kW (0.5 HP) and 4.0 kW (5.5 HP), whereas the three-phase line ranges between 0.37 kW (0.5 HP) and 7.5 kW (10 HP). The submersible motors are mainly used in vertical installations. However, these motors can be installed also horizontally prior confirmation from our technical department and global assessment of the required application.
Coverco motors can be installed in 4" wells with a maximum depth of 250 metres. The rewindable feature is ensured by a design that allows the motors to be disassembled and reassembled.
