Abstract

868,992. Raising liquids ; bellows pumps. PORTOVAC Ltd. Sept. 11, 1959 [Sept. 11, 1958], No. 29157/58. Classes 8(1) and 102(2). A bellows pump 6 is driven, through reduction gearing 5 from a battery driven electric motor 4. The suction side of the pump is connected to a suction bottle 16 whereby liquid may be drawn into the bottle ; a float actuated switch 24 stops the motor at a given liquid level. A control valve 14 and gauge 17 are included in the suction line. The outlet from the pump passes through a bacteriological filter 20. The various parts are in or on a portable casing 25.
