ABSTRACT:
A system is disclosed, suitable to suppress the discharge pipe string in a deep-well vertical pump. In said system, a top seal is provided located at the top end of the well to hermetically seal the well's wall and form a duct towards the discharge mouth of said well; another seal being located in a cooperative relationship to the upmost impellent device and to the inner wall of the well, in order to allow for the well's wall portion comprised between said both seals to operate as the discharge tubing; said seal being proportional to the fluid pressure inside said wall portion.
