The INDAR ISM ML Series is composed of submersible, water-filled motors designed for driving submersible pumps in a wide range of submerged applications.

The ML submersible range consists of  three phase, asynchronous motors with squirrel cage rotors (or short-circuited rotors).  They are cooled and lubricated with water and directly connected to the hydraulic part.

They are custom-made and designs are adapted electrically, mechanically and thermally according to special requirements or types of service.  The different construction options offered by INDAR, together with the range of materials available, make the ML series a highly-versatile product which provides ideal submersible solutions to an infinite range of requirements.

Main safety devices

  • Pt-100 in windings and/or axial thrust bearing
  • Level sensors for inverted configurations
  • Pressure compensation or regulation systems using an external pressure compensator, header tank, etc.
