Abstract: FIELD: oil industry. 
     SUBSTANCE: group of inventions relates to the field of submersible borehole pumps, such as electric submersible pumps, more specifically to labyrinth-type sealing sections that allow for holding dielectric fluid at ambient pressure in the well. A method for pumping fluid contains stages in which an engine connected by a transmission to a pump is rotated, wherein the engine and the pump are located in a case. The case contains a protective device located between the engine and the pump, wherein the protective device contains a section of a labyrinth seal. The labyrinth section for the submersible pump includes an outer case having a coupling hermetically engaged at each longitudinal end of the outer case. An inner pipe is hermetically engaged at each end with one of couplings to form a sealed annular space. In the annular space, there are many sections of labyrinth pipes, each of which contains labyrinth pipes engaged with end plates. Many sections of labyrinth pipes ensure the movement of fluid through labyrinth pipes and spaces outer to labyrinth pipes, and between end plates to fill the sealed annular space. One of sections of labyrinth pipes restricts the movement of fluid only inside labyrinth pipes, and the inner pipe between end plates of one of labyrinth pipes contains a hole for fluid into the inner part of the inner pipe.
