In consideration of environmental relief and energy saving, Franklin Electric has developed High Efficiency 4”, 6” and 8” Submersible Electric Motor Borehole Systems, consisting of synchronous submersible NEMA electric motors, associated variable frequency drives and output filters.

Advantages of the system:

  • One-stop shop – perfectly matching components guarantee first-class performance.
  • Up to 20 per cent energy saving* = system payback< 2 years
  • Up to 13 per cent improved motor efficiency (system up to eleven per cent) with excellent partial load behaviour
  • Significantly lower motor heat rise = increased lifetime
  • Higher power density* = lightweight
  • Easy setup due to tailored pre-setting, user interface and Franklin Electric’s own software
  • Speed control = optimum aggregate operation-pump matches system all the time
  • Incorporated soft start and protection features = increased lifetime = no additional investment
  • Reduced amps = reduced drop cable size
  • First-class protection with electronics in IP66/54 = easy retrofit – no additional cabinet cost
  • Power factor corrected input = no power compensation needed
  • Communication Modbus (RS485, Ethernet and optional Profibus)

*In comparison to current asynchronous technology

System Technical Specification:


  • 4” 1.1-7.5kW
  • 6” 4-37kW
  • 8” 75-150kW

System Power Supply:

  • Voltage 400V +/- 10%
  • Frequency 50Hz +/- 6%

Solar systems:

The High Efficiency Systems are ideal for larger solar pumping systems due to their superior efficiency, which in most cases results in less solar panels being required. The system can be standalone solar or incorporated into a blended system utilising solar, mains power or diesel generated power.
