FIELD: oil extraction from wells with high content of impurities. SUBSTANCE: lock-joint mount of pump provided with filter has double-step seating fitting with through channel accommodating top and bottom differential plungers installed for axial displacement and engageable with respective steps of seating fitting. Bottom plunger is provided with flexible member and is mounted for axial displacement at steady state inertial harmonic vibrations relative to top plunger. Inner surface of bottom plunger is made in the form of contraction and that of top plunger, in the form of diffuser; both are relatively arranged so as to form jet pump. Vacuum chamber of pump houses flexible member. Vacuum chamber proper hydraulically communicates with inner space of filter. EFFECT: improved delivery of pumps due to improved operating conditions of mount. 1 dwg
