FIELD: oil and gas industry.
SUBSTANCE: device relates to oil industry, namely to oil production devices, and can be used for oil production from wells with low production rate. Device contains a pump kinetic connected by the shaft with submersible electric motor. Submersible motor is installed in hollow casing to form channel between outer surface of said engine and inner surface of casing. Cavity of jacket is isolated from ambient medium. Pump intake is brought out of the casing cavity in the lower part of the device. Pump discharge is interconnected with casing cavity.
EFFECT: increased intensity of submersible electric motor cooling during oil production.
