Die Einrichtung gemäß
Sobald die Pumpe 1 in Betrieb geht, wird das zu befördernde Medium 2 mittels des Schaufelrades 18 in eine Richtung bewegt. Dabei entsteht ein Sog 16, der bewirkt, dass ein Anteil 3 des zu befördernden Mediums über die Zuleitung 4 in die Kammer 6 gezogen wird. Dort durchläuft der Flüssigkeitsanteil 3 eine chemische Substanz 7, wodurch er chemisch verändert wird. Danach wird er über einen Rückflussverhinderer 11 in den Motorraum 5 gezogen, wo er die Lager 12 schmiert und den Rotor 14 sowie den Stator 13 über die Kanäle 25 kühlt. Über das Lager 12 tritt der Flüssigkeitsanteil 3 aus dem Motorraum 5 aus und vereinigt sich wieder mit dem zu befördernden Medium 2.As soon as the
