Four Inch Motors

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

There is more information on the 3 phase motors at the bottom of this page.

All 4 Inch Motors

Franklin 2-wire Motors

The Franklin Electric 2-wire 4” Inch motors have a split phase motor with built-in starting components. These motors have 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’.

2-wire (3 core) submersible electrical drop cable is used with this motor.

The motor protection device for the 2-wire Franklin Motors is the PUMPTEC IR or the PUMPTEC PLUS.

Franklin 3-wire Motors

The Franklin Electric 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.

These motors require a Control/Starter Box which contains the capacitor and motor overload protection. You can find these on this website here. Then scroll down to see the 1Phase Control Box and choose the model with the same motor rating (kw/hp) as the motor.

3-wire (4 core) submersible electrical drop cable is used with this motor.

The motor protection device for the 3-wire Franklin Motors is the PUMPTEC IR or the PUMPTEC PLUS.

Franklin Psc Motors

The Franklin Electric 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 or solar as it has a lower start current.

These motors require a Substart SC (starter box) which contains the capacitor and motor overload protection. Motor warranty is void if Franklin Electric 1 phase Substart control box / starters are not used. You can find these on this website here. Then scroll down to see the Substart SC and choose the model with the same motor rating (kw/hp) as the motor.

3-wire (4 core) submersible electrical drop cable is used with this motor.

The motor protection device for the PSC Franklin Motors is the PUMPTEC PLUS.

Franklin Three 3 Phase 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.

3-wire (4 core) submersible electrical drop cable is used with this motor.

The motor protection device for the 3 phase Franklin Motors is the SUBMONITOR.
