Abstract: The spinning pump for melt spinning of polyamides includes a back plate (5), a front plate (7), a central plate (6) extending between the front plate (7) and the back plate (5) and a pair of gear wheels (8,8'). The central plate (6) is provided with a bore (10) for feeding a melt into the central plate and another bore (10') for feeding the melt out of the central plate. The bores (10,10') each have transverse partially circular cross sections with cross-sectional areas decreasing from the front side (6') of the central plate (6) to the back side (6"). The partially circular cross sections of each of the bores (10,10') have center points on a parabolic arc or path (13b) from the front side (6') to the back side (6") of the central plate (6). This shape and structure for the bores (10,10') prevents cracked deposits from forming inside the pump channels and increases the productivity of top-quality melt extrusion by over 10%.
