4" 3-Phase High Thrust Motors
4" 3-Phase High Thrust Motors
Franklin Electric 4" encapsulated submersible motors, built in ISO 9001 certified facilities for outstanding performance in 4" or larger water wells.
The 3-phase motor offers maximum life and highest efficiency under various load conditions in combination with a 6500 N thrust bearing. It should ideally be combined to the Franklin Electric SubStart/SubTronic3P control boxes for maximum system performance, protection and warranty.

Standard Motor Design Specifications
- Hermetically sealed stator with 316SS shell. Anti track, self healing stator resin prevents motor burn out, mechanically supports the winding and provides fast heat dissipation.
- High efficiency electrical design (low operation cost, cool running winding)
- Removable water bloc lead connector
- No-wear, water lubricated radial and thrust bearings for 100 % maintenance free operation
- Non-contaminating FES 93 filling liquid
- Max. storage temperature -15°C - + 50°C
- Various agency approvals for use in drinking water
Brackish Water version Specifications:
- For use in water that has more salinity than fresh water, but not as much as seawater.
- The novel Franklin Electric Brackish Water Motor proposes a cost-effective solution wherever standard 4" motors are not giving sufficient service life.
