摘要

FIELD: moving, proportioning and mixing liquid media. SUBSTANCE: relative planetary motion of screw 3 sets substance in motion over helical thread in axial direction. Additional kinematic linkage of screw 3 and holder 2 excludes their wear. Corrugated diaphragms 7 provide for sealing up the passage of substance in pump. EFFECT: enhanced efficiency. 2 dwgf
