According to another aspect of the present invention the first and/or second parts is provided by the first and/or second extension.

Izobreteyonija on the claim, the typical way is only considered the situation before the blades of the impeller and after them. It is possible that we neglect the losses that occur in the flow channel and in the suction pipe. In particular, the configuration of the third section should be such that occur in the suction pipe hydrodynamic load decreased. For this purpose, the roof of the flow channel in the third section must have a corresponding configuration. The configuration of the roof of the flow channel on the third area affected, but also on the angle of rise in the suction pipe or, respectively, in the second section of the flow channel. Due to the improved configuration of the roof of the flow channel in the third section the necessary elevation angle of the second area can be reduced. This can be done, in particular, through the use of steel for reducing hydrodynamic loads. Thus, it can be made smaller angle of elevation is increased, the radii of curvature and better flow properties in the flow channel 40.
