Zusammenfassung:	A pump for evacuating heavy oil containing mechanical impurities and embedded in strata is disclosed. The pump includes one or more tanks, each with a flexible membrane, situated in an external pump casing. Each flexible membrane divides each tank into two compartments. The first compartment of each tank is in fluid communication with a collector cavity. The second compartment of each tank is in fluid communication with a suction cavity. The suction cavity includes a suction valve and a forcing valve. The pump also includes a hydraulic drive connected with the collection cavity so that operational fluid from the hydraulic drive is forced against the membrane upon insertion of a hydraulic rod and creates suction against the membrane upon extraction of the rod. The external pump casing also includes a change lever for connecting to external pipes.
