FIELD: pumping equipment. SUBSTANCE: resilient diaphragms 1 and 2 with rigid centers are connected together by rod 7 which passes through partitions 5 in case 6. Diaphragms 1 and 2 are mounted in case 6 for forming pump and drive chambers 8, 9 and 10, 11. Chambers 10 and 11 are filled with drive medium and connected to hydraulic pulser which has pump 12 and four controlled hydraulic members which are connected hydraulically according tp a bridge circuit. Blades are mounted onto rod 7 in chambers 8 and 9 close to diaphragms 1 and 2. Medium part of rod 7 and partition 5 are made in form of a screw pair. Rod 7 is mounted for rotation about centers. Magnetorheologic suspension is used as drive medium. Hydraulic members 13 are made in form of magnetorheologic restrictors and provided with electric control unit 17. Rod 7 is hollow. Hydraulic pulser is provided with hydraulic accumulator. EFFECT: improved reliability; widened functional capabilities of portioning pump. 3 cl, 3 dwg
