Abstract
Protective tube for submersible pump transmitter shaft, essentially characterized in that each of the tubular sections that surrounds the aforesaid axis is constituted by a rigid one-piece body and falls plastic nature, whose respective mouths are coupled on the external part of each intermediate bearing in which the shaft supports, for which purpose, each bearing has a peripheral groove at its ends that houses an O-ring operatively arranged to press, in the assembly between the tube and bearing on the dumbbell of the mouth of the tubular section itself, establishing said joint simultaneously retains and tightly engages between the tubular section and the support bearing of the transmitter shaft.
