Franklin Electric 4" encapsulated submersible motors, built in ISO 9001 certified facilities for outstanding performance in 4" or larger water wells.

The 1-phase 3-wire motor has been designed for highest achievable starting torque and shaft power from 1-phase power supplies. It is therefore ideally suited for applications where starting torque is paramount and 3-phase motors cannot be used. It should ideally be combined to the Franklin Electric 3-wire control boxes for maximum system performance.
