Abstract (en)
[origin: EP1348871A1] The pump consists of a number of wheels mounted on the same shaft, each wheel having two flange faces (19) which contain channels and blades. The channels and blades conduct a fluid from an entry at the wheel hub to an output orifice (15) at the periphery. A specifically profiled indentation (17) is located on the flange opposite to entry to drive bubbles
