FIELD: equipment for delivery and dosed supplying of fiber-forming solution under pressure to fiber forming working position. SUBSTANCE: pumping unit has housing fixed on pipe of feeding fiber-forming solution pipeline and provided with projections for pivoted attachment of removable hydraulic units between them by means of axially aligned nipples and stops positioned in projections openings. Parts of projections are provided with feeding channels for communicating hydraulic units with cavity of fiber-forming solution pipeline or joined with discharge channels for communicating these hydraulic units with outlet members for delivering of solution to the unit of fiber-forming system. Pumping column has at least two straight rows of projections extending in parallel with longitudinal axis of fiber-forming solution pipeline. Each row has at least two projections with axially aligned openings, with one projection being provided with supplying channel and other projection being joined with discharge channel. Supplying channels of each projection of rows of projections are positioned in respective radial planes extending through longitudinal axis of solution pipeline and common axis of openings of respective row of projections. Mentioned radial planes are positioned at any acute angle of < αn < 2π about longitudinal axis of solution pipeline or one relative to another. EFFECT: increased efficiency and enhanced reliability in operation. 2 cl, 2 dwg
