FIELD: pumps.
SUBSTANCE: invention relates to a pump engineering industry, in particular, to submersible pumping units driven by a sealed submersible electric motor for pumping a well fluid. Installation of a submersible pump contains a pump, an engine and a magnetic coupling consisting of driving and driven coupling halves with permanent magnets mounted on the motor rotor and the pump rotor, respectively, a protective shield between them and an intermediate bearing support. Installation further comprises a device for cooling the magnetic coupling. As a device for cooling the magnetic coupling, a separator or a package of pumping stages can be used.
EFFECT: invention provides long-term installation operation at high shaft rotational speeds and high values of torque on the shaft.
