  • 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.
