Beschreibung
Zusammenfassung:	FIELD: oil industry, particularly pumping oil production from wells characterized by mechanical injuries in well product. ^ SUBSTANCE: pumping installation comprises pump lowered in well and provided with submersible electrical motor, centrifugal solid particle separator and precipitation tank. Centrifugal solid particle separator is arranged below submersible electrical motor and may transmit torque from submersible electrical motor shaft to centrifugal solid particle separator shaft. Centrifugal solid particle separator rotor is enclosed with fixed helical grid. Helical grid blade direction is opposite to direction of centrifugal solid particle separator rotor rotation. ^ EFFECT: increase efficiency and reliability of pumping installation operation for oil production from well with high content of suspension solid particles. ^ 6 cl, 3 dwg
