Abstract

The guiding device for a circulating pump has an impeller housed in a casing (1). The region of the rear casing section (3) allocated to the bladed extended section of the impeller continues in an axially orientated inner annular passage-casing wall extending from the impeller in the axial direction and encompassing the pump axis, and then continues in a radially orientated first radial annular face extending from the pump axis in the radial direction. The front casing section (2) allocated to the bladed section of the impeller after a transition section (2d) continues into an axially orientated outer annular passage-casing wall encompassing the pump axis.
