Abstract

A pumping system deployable in a wellbore includes a primary driven component, a secondary driven component and a motor. The motor is filled with a motor lubricant and includes a stator, a primary rotor assembly configured for rotation within the stator and a primary shaft connected to the primary rotor assembly and to the primary driven component. The motor further includes an internal magnetic coupling assembly inside the stator. The internal magnetic coupling assembly includes a secondary rotor assembly and a secondary shaft. The secondary rotor assembly and the secondary shaft are isolated from the motor fluid.
