4 inch Three Phase High Thrust Motor Franklin Electric

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
• Various agency approvals for use in drinking water

Brackish Water version Specifications:
