PURPOSE: To prevent the leakage of a spinning fluid from a spinning pump by preventing the generation of a shortcircuit flow of the spinning fluid from a spinning fluid introduction tube to an exhaust tube through the connection face between the spinning pump and a spinning pump table.

CONSTITUTION: In a spinning pump 1 whose base plate 4, gear plate 5 and cover plate 6 are connected on a spinning pump block 2 by means of fastening screws 3, an adaptor part 15 is connected to the cover plate 6, and grooves 16 are formed on the adaptor part 15. Here, passage bores 12 for fastening screws 3 lie in the region of the grooves 16, and the depth of a groove 16 is adjusted so that the intersection of an inlet tube 8 and an outlet tube 9 lies inside the perpendiculars from the heads of the grooves 16.
