Applications

Introduction


F.B.’s 10’’ rewindable motors are studied for long-term operation in wells with diameters of 10’’ 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.
BRONZE-ALUMINIUM, AISI 316, DUPLEX, AISI 904L and SUPER DUPLEX motors are available for applications in aggressive water.
