FIELD: oil and gas production.
SUBSTANCE: device consists of stator rigidly fixed on tubing sting (TS) in form of washer with channels, of rotor with impeller and of propagating element. The stator channels are at angle to plane of the rotor impeller. The rotor is positioned between the stator and the propagating element. The TS with elements secured to it travels along a section of a perforated casing string. The stator, rotor and propagating element are attached to a lower section of the TS. The washer has a bell mouth rigidly fixed on the end of the TS. The end of the TS in the bell has orifices. The propagating element is fixed on external surface of the TS rigidly or rotationally.
EFFECT: versatility and simplicity of design.
