Submersible Motors

Gransa “GW series” motors are deep well / borehole rewindable submersible type, pre-filled with water, which acts as coolant and lubricant. These motors are available in three phase power supply and suitable for both normal & high temperature applications. Rotors are supported with bush and thrust bearings to withstand maximum axial and radial thrust loads. All mounting dimensions are in accordance with NEMA standards.
