Abstract
1,266,510. Axial-flow pumps. SIEMENS A.G. March 26, 1969 [March 26, 1968; March 30, 1968], No. 15928/69. Heading F1C. In a self-priming axial-flow pump, e. g. for a dishwashing machine, having an impeller 3 mounted within an annular impeller chamber provided externally with a separating chamber 9 communicating with the impeller chamber through two ports 11, 12, air drawn into the pump through inlet 5 is mixed with liquid therein and the mixture is delivered through port 12 into the separating chamber from where the separated liquid is returned to the suction side 4 of the impeller chamber via port 11. The clearance gap at the impeller periphery provides the necessary flowpath for the return of the separated liquid to the suction side 4. The separating chamber has a wedge-shaped rib 13 therein which deflects the liquid in the mixture away from outlet 10, thereby enabling some of the air to flow through the outlet. Further air is separated from the mixture when the latter impinges on the liquid at the bottom of chamber 9.
