The INDAR SP UGP Series Submersible electropump set consist of a vertical multistage centrifugal pump, and an ISM ML electric motor directly coupled to the pump.
The INDAR ISM ML electric motors are submersible, asynchronous, three-phase, squirrel cage rotor types. These motors must operate filled with water (or a mixture of water and antifreeze) and be fully submerged.
The lubrication of the bearings is done by the motor filling liquid. Cooling is accomplished by the motor filling liquid and the pumping water surrounding the unit.
The ISM ML motors are designed exclusively for the operation of vertical centrifugal pumps.
