Abstract

The rotary pump has a feed pump unit, with inlet sections, nozzle, and diffuser. The diffuser is connected to the inlet aperture of the rotary pump. The inlet section (5), nozzle (6), and diffuser (7), are located on a plane, which is mainly perpendicular to the shaft of the rotary pump. The diffuser has an inner channel unit (8), with rising flow cross section, and a co-axial jacket unit (9). This turns the fluid through the diffuser by 180.deg. and forms an even rising flow cross section, seen in flow direction, in the ring space (11) between channel unit and jacket.
