Abstract: A radial pump for water has a drive motor, a pump chamber and an impeller revolving in the pump chamber. The impeller has a plurality of impeller blades which are designed, at least in regions, to be elastic and have a fixed mounting arranged in a region located near the impeller axis of rotation. They can bend elastically radially outward from this fixed mounting counter to a spring force.

Abstract: A pump having a pump chamber and an impeller which rotates therein has an inlet leading into the pump chamber and an outlet leading out of the pump chamber, the pump having a pump motor having a rotor. The rotor and the impeller are connected to each other, the impeller being supported in an axial direction towards the inlet and an axial support being provided therefor against an axial bearing. In this instance, the axial bearing is located on a rotation axis of the rotor and includes a centrally supported concave bearing shell in which a convex-curved bearing projection of the impeller is in abutment.

Abstract: An impeller radial pump includes a pump chamber with a central suction and with a pump chamber outlet, wherein an impeller is provided in the pump chamber. Radially outside of the impeller, a circular ring shaped and circumferential pump chamber ring section is provided as a part of the pump chamber, wherein the pump chamber ring section essentially has an extension along the axial direction of the pump from the impeller against the suction direction. The pump chamber ring section has a varying width and is configured to be narrower in a compression region in the circulation direction.

Abstract: In a centrifugal pump for pumping a fluid with central axial suctioning and radial discharging of the fluid to be pumped out of the impeller, the impeller includes an upper cover plate and a lower cover plate and multiple interposed blades therebetween. In the radial inner region, the blades extend essentially parallel to the rotation axis of the impeller in the axial direction of the pump and thus are upright, wherein said blades in the course radially outwards thereof are increasingly inclined or extend oblique.

Abstract: A liquid pump has a rotor in a pump housing which has a pump chamber, a pump base, a pump-chamber wall and a cover. The rotor rotates just above the pump base, the pump-chamber wall being provided around the outside of and slightly spaced apart from the rotor and having a heating means thereon. An inlet to the rotor is provided centrally in the axial direction towards the rotor and an outlet from the pump housing is provided externally at the periphery of the pump-chamber wall. Blade-like guiding elements which are integrally injection-moulded thereon are arranged on the pump base, radially outside the impeller.

Abstract: A radial pump for fluids has a central water inlet that leads to a rotating impeller that is enclosed by an annular pump chamber extending radially outside the impeller and from which leads a water outlet. An intermediate wall is arranged in the pump chamber which is of an encompassing design and divides the pump chamber into an annular inner region, lying radially on the inside, and an annular outer region, lying radially on the outside. These regions, at one end of the pump chamber that is remote from the impeller, merge into each other through openings in the intermediate wall, wherein the water outlet projects from the outer region.

Abstract: A flow-guiding device for an impeller radial pump is arranged radially outside the impeller and extends in a ring-shaped manner with a circumferential carrier ring on which several guide blades are arranged. These latter are formed so as to be resilient in such a manner that when there is a small fluid flow a blade angle points more in the radial direction at an angle of approximately 70° with respect to the longitudinal center axis of the pump. When there is strong fluid flow, the angle becomes smaller and the guide blades bend in a resilient manner at least in regions such that they stand at a smaller angle of between 30° and 40° with respect to the longitudinal center axis of the pump. The fluid is conveyed better in the pump chamber in this way.

Abstract: A pump for a dishwasher has an impeller for conveying fluid, wherein it is formed as a centrifugal pump with the fluid to be conveyed being sucked-in in a central axial manner and flowing out in a radial manner. The impeller extends on a bottom surface above a pump base, wherein several fixed flow directing blades are arranged radially outside the impeller, said flow directing blades extending in a helicoidal manner with the pitch extending in the rotational direction of the impeller away from the pump base. At least one flow directing blade extends as far as up to the bottom surface of the impeller for picking up a circulating funnel or tube produced of fluid with air bubbles therein.

Abstract: A latching device for a pump housing for production of a releasable latched connection between two housing parts has, on a first housing part, an elongate latching hook comprising a latching protrusion on the upper side and introduction chamfers on the upper side and on the underside. A latching opening is provided in the second housing part and comprises a latching tongue defining the latching opening outwardly, the latching protrusion abutting this latching tongue. An introduction web is arranged on the underside of the latching opening and comprises an introduction chamfer for the latching hook. Two securing tongues engage laterally in the latching opening and protrude via a free tongue end into the path of the latching hook when said latching hook is inserted into the latching opening. They prevent an undesired automatic release of the latched connection caused by movement of the latching hook in a downwards direction.
