Abstract (en)
[origin: EP0601220A1] In order, in a washing-up liquid drain pump which is driven by a single-phase synchronous motor (1), to be able to achieve a maximum conveying capacity in a very short time after switching back on, a pump housing (2) is provided with a pressure joint (22) which leaves essentially horizontally in the use position and which is offset upwardly in relation to the axis (34) of the pump impeller (3) in such a manner that a gas bubble (4), which remains in the pump housing (2) above the remaining liquid (8) when the pump impeller (3) stops, can extend at least partially into the region of the pressure joint (22) also. <IMAGE>
