Franklin 4 inch Submersible Motors

Franklin 4 inch submersible motors from 1 Phase 2-wire, 3-wire, 3w-PSC and 3 Phase are designed for 4″ diameter or larger bores and wells. Their premium motor protection system protects the motor against overload, underload, overheating and rapid cycling.

Single 1 Phase 2-wire Franklin Motors

The 2-wire motor is a split phase motor with built-in starting components. It has an automatic reset overload and surge protectors. The Franklin 2-wire motor is designed for direct connection to the single-phase power supply with no need for a control box. The advantages of this motor design is the ease of installation along with the unique ‘reverse impact torque’.

Single 1 Phase 3-wire Franklin Motors

The Franklin 3-wire motors are single phase capacitor start induction run (CSCR) motors which require a starter / control box. The design features the highest starting torque within the single phase motor range. Franklin Electric control boxes include all necessary long-life starting and motor protection relays and capacitors.

Single 1 Phase PSC Franklin Motors

The Franklin PSC motor is a single 1 phase motor with run capacitor. This motor requires a Substart SC (starter box) which contains the capacitor and motor overload protection. The motor is connected to only one capacitor which works permanently as start and run capacitor. The Substart SC is available for these motors. Good for use with a genset as it has a lower start current.

3 Phase Franklin Motors

These motors are fitted with water lubricated radial and thrust bearings for maintenance free, long-life operation. the motors are filled with a fluid providing frost protection down to -15°C. A special diaphragm ensures pressure compensation inside the motor
