Abstract

Aggregat zur Aufnahme heißer Fluide, insbesondere Kreiselpumpe zur Förderung heißer Fluide, wobei eine Welle einen Dichtungsraum durchdringt, im Dichtungsraum mindestens eine Gleitringdichtung angeordnet ist, zwischen Aggregat und Dichtungsraum eine fluidführende Verbindung besteht, und die Gleitringdichtung durch das dem Aggregat entstammende Fluid gekühlt und gespült wird. An oder in der aggregatseitigen Wandfläche des Dichtungsraumes ist im Bereich der Wellendurchführung ein Isolierteil angeordnet.

Figure 00000001
Unit for receiving hot fluids, in particular a centrifugal pump for delivering hot fluids, whereby a shaft penetrates a sealing space, at least one mechanical seal is arranged in the sealing space, there is a fluid-carrying connection between the unit and the sealing space, and the mechanical seal is cooled and flushed by the fluid coming from the unit , An insulating part is arranged on or in the wall surface of the sealing space on the assembly side.
