F.B.’s 6” rewindable motors are studied for long-term operation in wells with diameters of 6” or greater. Water-lubricated axial and radial bearings ensure a long service life and maintenance-free operation. The motors are pre-filled with a special antifreeze fluid so that they can be stored down to -15°C. A special membrane compensates the pressure inside the motor.
