Here he is protected by the temperatures of the aggregate, so that no harmful larger temperature fluctuations in the box can occur.

Bei der/den Wärmedämmungsschale(n) handelt es sich nicht um ein im Abstand zum Aggregat angeordnetes Gehäuse, sondern die Wärmedämmungsschale(n) umschließt/umschließen das Motor-Pumpen-Aggregat eng.The insulation shell (s) is not one at a distance to the aggregate arranged housing, but the heat insulation shell (s) encloses / surrounds the motor-pump unit closely.

Vorzugsweise wird vorgeschlagen, dass der Kasten lösbar befestigt ist. Auch ist von Vorteil, wenn der Kasten form- oder kraftschlüssig befestigt ist.It is preferably proposed that the box is releasably secured. Also is advantageous if the box is positively or non-positively attached.

Eine besonders vorteilhafte Ausführung ist dann gegeben, wenn die Außenseite der Schalenwand der Wärmedämmung mindestens einen Vorsprung aufweist, der in mindestens einer Ausnehmung des Kastens formschlüssig einliegt. Hierbei kann der Kasten mit mindestens einem insbesondere schwalbenschwanzförmigen Vorsprung in der/den entsprechend geformten Ausnehmung(en) der Wärmedämmungsschale einliegen.A particularly advantageous embodiment is given when the outside the shell wall of the insulation has at least one projection, the rests positively in at least one recess of the box. in this connection the box may have at least one in particular dovetail-shaped Projection in the / the correspondingly shaped recess (s) of Insert heat insulation shell.

Eine sehr vorteilhafte alternative Ausführung besteht darin, dass in der Außenseite der Schalenwand der Wärmedämmung eine sich nach außen öffnende Ausnehmung ist, in der der Kasten vollständig oder teilweise formschlüssig einliegt. A very advantageous alternative embodiment is that in the outside the shell wall of the thermal insulation opens outward Recess is in which the box completely or partially positive rests.

Ferner kann der Kasten angeschraubt und/oder durch mindestens einen Klettverschluss befestigt sein. Vorzugsweise wird vorgeschlagen, dass der Kasten ein Schaltnetzteil und/oder einen Frequenzumformer für den Motor aufweist.Furthermore, the box can be screwed on and / or by at least one Velcro fastened. It is preferably proposed that the box a switching power supply and / or a frequency converter for the motor has.

Besonders vorteilhaft ist es, wenn die Wärmedämmungsschale auf ihren beiden Seiten gleich geformt ist, so dass der Kasten wahlweise auf der einen oder der anderen Seite der Pumpe befestigbar ist.It is particularly advantageous if the heat insulation shell on their two Pages is shaped the same, so that the box either on the one or the the other side of the pump can be fastened.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung in einer Seitenansicht dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is in the drawing in a side view and will be described in more detail below.

Das Aggregat weist einen Motor 1 auf, an dessen Gehäuse das Gehäuse 2 einer Kreiselpumpe befestigt insbesondere angeschraubt ist. Das Gehäuse 2 weist einen Saugstutzen 3 und einen Druckstutzen 4 auf, die in diesem Ausführungsbeispiel einander gegenüberliegend koaxial und rechtwinklig zur Pumpenachse angeordnet sind.The unit has a motor 1, on whose housing the housing 2 a Centrifugal pump attached in particular screwed. The housing 2 has a suction nozzle 3 and a discharge nozzle 4, which in this Embodiment opposite coaxial and perpendicular to the Pump axis are arranged.

Das Gehäuse der Pumpe ist von einer zweiteiligen Wärmedämmungsschale 5 engumgeben, das aus zwei Schalenhälften 5a und 5b besteht. Unter Wärmedämmungsschale(n) wird hier kein Gehäuse sondern eine Wärmedämmschicht verstanden, die wie eine zweite Haut das Pumpenaggregat eng umgibt und keine Zwischenräume zwischen der Schale und der Aggregataußenseite freilässt.The housing of the pump is of a two-part heat-insulating shell. 5 Engumgeben, which consists of two shell halves 5a and 5b. Under Thermal insulation shell (s) is not a housing but a Thermal insulation layer understood, which like a second skin the pump set tightly surrounds and no spaces between the shell and the Leaves aggregate outside free.

An der Außenseite jeder Schalenhälfte 5a, 5b befestigt ist ein schwalbenschwanzförmiger Vorsprung 6, auf dem ein Kasten 7 in der Weise befestigbar ist, dass eine an der Kastenaußenseite vorgesehene Ausnehmung 8 des Kastens über den Vorsprung 6 von der Seite her schiebbar ist, da die Ausnehmung 8 entsprechend dem Vorsprung 6 schwalbenschwanzförmig ausgebildet ist, so dass eine formschlüssige Verbindung zwischen dem Kasten 7 und der Schalenhälfte 5a besteht. Attached to the outside of each shell half 5a, 5b is a dovetailed projection 6 on which a box 7 in the way can be fastened, that provided on the outside of the box recess 8 of the box on the projection 6 is pushed from the side, as the Recess 8 according to the projection 6 dovetailed is formed, so that a positive connection between the box. 7 and the shell half 5a.

Statt einem Vorsprung 6 können auch mehrere Vorsprünge an der Schalenhälfte 5a vorgesehen sein, die in entsprechenden Ausnehmungen in der Kastenseitenwand einliegen. Im Ausführungsbeispiel weist darüber hinaus der Kasten 7 zwei Vorsprünge 9a und 9b auf, die in entsprechenden Ausnehmungen 10a, 10b der Schalenhälfte formschlüssig einliegen.Instead of a projection 6 can also have a plurality of projections on the shell half 5a provided in corresponding recesses in the Insert box side wall.
