Side-channel pump with asymmetrical cross-sections of the side channels

Side-channel pump with asymmetrical cross-sections of the side channels

The invention relates to a side-channel pump that allows a reduced wear. The side-channel pump has a housing which encloses a pump chamber (7). An impeller (3) is received so as to be rotatable inside the pump chamber (7). An inlet side channel (31) and an outlet side channel (33) are also formed in...

description The invention relates to a side-channel pump that allows a reduced wear. The side-channel pump has a housing which encloses a pump chamber (7). An impeller (3) is received so as to be rotatable inside the pump chamber (7). An inlet side channel (31) and an outlet side channel (33) are also formed inside the pump chamber (7). The impeller (7) has, in a blade region near the circumference thereof, a plurality of radially outward-extending blades (11). The inlet side channel (31) and the outlet side channel (33) run on opposite sides of the impeller (3) and both adjoin the impeller (3). The two side channels (31, 33) both extend in a partially annular shape along a flow path from an inlet channel to an outlet channel. The proposed side-channel pump is characterized in that the inlet side channel (31), averaged along the flow path, has a smaller cross-section than the outlet side channel (33). In this manner the impeller (3) can be maintained in a force equilibrium during operation. The friction between the impeller (3) and adjoining walls (19, 21) can be kept small and thereby wear phenomena can be kept small.
