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. 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
- 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.
