    • The flow pump has an impeller, driven in a pump chamber and having a ring of blades spaced apart from one another in the circumferential direction on at least one end face and ending at the face end of the impeller and cooperate therewith to define blade chambers. In the pump chamber, at least one feed conduit in the form of a split ring cooperates with the ring of blades on the impeller, and at least one intake opening discharging into the feed conduit is embodied in a pump chamber wall that defines the pump chamber in the direction of the pivot axis of the impeller. In an initial region at the at least one intake opening and/or in the circumferential direction of the impeller, adjoining the impeller, the feed conduit extends radially farther inward than the blade chamber bottom of the impeller, and the transition between a radially inner blade chamber bottom of the blade chambers and the associated face end of the impeller has a chamfer or rounded corner.
    • 流动泵具有叶轮,该叶轮在泵室中驱动并且具有在至少一个端面上在圆周方向上彼此间隔开并且在叶轮的端部处终止并且与其配合以限定叶片室的叶片环。 在泵室中,至少一个分流环形式的进料导管与叶轮上的叶片环相配合,并且排入进料管道中的至少一个进气口被实施在泵室壁中,泵室壁限定泵室 在叶轮的枢转轴线的方向上。 在与叶轮邻接的至少一个进气口和/或沿圆周方向的初始区域中,进料导管比叶轮的叶片室底部径向向内延伸,并且径向内叶片 叶片室的腔室底部和叶轮的相关联的端部端部具有倒角或圆角。

    • The unit includes an electric drive motor (12) and a pump section (24) that are situated next to each other in a common housing (10) designed at least nearly in the shape of a hollow cylinder. The pump section (24) comprises a delivery element (26) rotating in a pump chamber (30), and one wall (32, 34) each forms a boundary of the pump chamber (30) with the drive motor (12) and with the outside of the housing (10) in the direction of the axis of rotation (28) of the delivery element (26). The walls (34) forming the boundary of the pump chamber (30) with the outside of the housing (10) is formed as a single component with the housing (10), and the walls (32) forming the boundary of the pump chamber (30) with the drive motor (12) is inserted into the housing (10) as a separate component. Due to the fact that the wall (34) forming the boundary of the pump chamber (30) with the outside is integrated with the housing (10), no separate steps are required to manufacture and assemble said wall and housing, and the pump chamber (30) is sealed off completely from the outside of the housing (10), because no joints are present that would have to be sealed off.
    • 该单元包括在设计成至少几乎为中空圆筒形状的公共壳体(10)中彼此相邻定位的电驱动马达(12)和泵部分(24)。 泵部分(24)包括在泵室(30)中旋转的输送元件(26)和一个壁(32,34),每个壁(32,34)与驱动马达(12)形成泵室(30)的边界,并且与 所述壳体(10)在所述输送元件(26)的旋转轴线(28)的方向上的外侧。 形成具有外壳(10)外侧的泵室(30)的边界的壁(34)与壳体(10)形成为单个部件,并且形成泵室边界的壁(32) (30)与驱动马达(12)作为单独的部件插入到壳体(10)中。 由于形成具有外部的泵室(30)的边界的壁(34)与壳体(10)一体化,所以不需要单独的步骤来制造和组装所述壁和壳体,并且泵室 (30)从壳体(10)的外部完全密封,因为不存在必须密封的接头。
