Example Embodiment
[0029] according to figure 1 The pump 1 includes a cylindrical pump casing 2 with a cover 3 mounted on the upper side. Cover 3 can hold figure 1 Heating elements not shown in, for this reason the cover is made of a thermally conductive material, such as metal.
[0030] A pump impeller 4 is arranged inside the pump casing 2, and the pump impeller is basically composed of an upper cover 5 and a lower cover 6 with blades 7 arranged therebetween. The blades 7 are bent and shaped in this way, so that when the pump impeller 4 rotates, the liquid in the pump impeller 4 forms a corresponding annular flow.
[0031] The pump impeller 4 is provided on the lower side with an axial protrusion 8 having a central hole 9 to receive a drive shaft not shown in detail. Therefore, the pump impeller 4 is driven from the side opposite to the heating element or cover 3.
[0032] The upper cover 5 has a central opening 10 into which an inlet pipe joint 11 extends. One outlet pipe joint 12 in image 3 It...
