FIELD: engines and pumps.
SUBSTANCE: unit includes the submersible centrifugal pump (1), made in the form of a package of steps connected by threaded coupling rods (2), a suction head (3) with the pump and submersible motor (4). The motor (4) is placed in a pipe casing (5) attached to the pump (1) by its upper flange (6) by threaded tie rods (2), passed through its holes and fixed against them. In the lower part of the electric motor (4), there is a centralizer (7), mainly of the damper type.
EFFECT: invention is aimed at increasing the reliability of a submersible centrifugal pumping unit of the UETPK type with a pump that is much larger than the diameter of the submersible motor.
