FIELD: mining. SUBSTANCE: device may be used in submersible electric centrifugal pumps in recovery of oil or some other minerals in the form of gas-fluid mixture for removal of gas and mechanical impurities from them. The device has a tubular body with head receiving filter in device base and shaft. The device also has rings and guide working apparatuses rigidly connected to base and the latter are provided with pockets-sacks on their periphery for trapping and settling of mechanical particles. Bearings are installed on shaft above and below rings. Rings and guiding apparatuses form between them cavities. Guiding working apparatuses are made so that gas-fluid mixture passing then becomes rotating along shaft. EFFECT: increased service life and stability in operation of pump unit. 2 dwg
