Abstract: An impeller pump for a dishwasher has a pump housing comprising a pump upper portion, pump lower portion and pump outer wall in which a pump chamber is arranged. It has a pump inlet into the pump housing and a pump outlet out of the pump housing and a heating device, which forms the pump outer wall, and a pump drive having a drive rotor, a drive stator having a stator winding and a bearing shaft. The bearing shaft is fixedly arranged on the pump housing and the drive rotor is fixedly connected to the drive rotor and they are rotatably arranged on the bearing shaft. The stator winding is arranged on a region of the pump lower portion which adjoins the pump chamber at the other side thereof in an outward radial direction so that between the pump chamber and stator winding only one wall of the pump lower portion extends so that the stator winding is surrounded by the pump chamber in an annular manner. It can thus be effectively cooled by water in the pump chamber.

Abstract: A pump for delivering fluid has a pump housing and a pump chamber having a pump chamber cover and a pump chamber base in said pump housing, an inlet and an outlet. In the pump chamber, an impeller rotates on a rotor shaft which is connected to a drive motor. The inlet is arranged in the pump chamber cover and the outlet is arranged below the impeller in the axial direction of the pump at that end region of the pump chamber which is remote from the inlet close to the outlet. The distance from the inlet to the outlet with the impeller therebetween can correspond approximately to the diameter of the pump chamber.

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: A plug connector has a housing and a plurality of metallic plug connections in the housing together with a plurality of contact feet which project from the bottom face of the housing in order to make electrical contact and be mechanically fixed to a support of a heating apparatus which is electrically connected to the plug connector. A contact foot has a U-shaped foot end with two limbs and with a cutout in-between, an upper limb merging with the contact foot, and a lower limb being provided on that side which faces away from the housing.

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.

Abstract: A heat-pump apparatus for heating purposes has a collector circuit for a heat source with a collector pump for a collector fluid, also has a refrigerant circuit with an evaporator and a condenser for a refrigerant in the refrigerant circuit and with a compressor and a pressure-relief valve, and additionally has a heating circuit with a heating pump for a heating fluid, with heating means for heating purposes. At least the collector pump and/or the heating pump are/is designed in the form of a pump with a heatable pump chamber for heating the fluid delivered by the pump.

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.
