FIELD: pumps building.
SUBSTANCE: invention relates to pumping units for simultaneous-separate operation of two well formations. Proposed plant comprises upper and lower pump units suspended on flow column and separated by packer and consisting of electric motor, hydraulic protection, inlet module and submersible pump. Components of the upper pump unit are equipped with tubular shafts, axial holes of which together form a continuous flow channel communicating the output of the lower pump unit with the flow column and acting as a bypass pipe.
EFFECT: technical result consists in design simplification.
