Schrauben-Vakuumpumpen
Zwei gegenläufige Schraubenrotoren fördern das Gas berührungsfrei vom Einlass zum Auslass. Ölgeschmiert oder trocken, drehzahlgeregelt – die Grundlast unserer Zentralanlagen und die erste Wahl für Dauerbetrieb mit wechselnder Last.
Funktionsprinzip
So arbeitet eine Schraubenpumpe
Im Pumpengehäuse laufen zwei Schraubenrotoren gegenläufig, ohne sich zu berühren. Das Gas wird am Einlass in den Gewindegängen eingeschlossen, entlang der Rotoren zum Auslass gefördert und dort verdichtet – ohne Ventile und ohne Schieber. Weil die Rotoren einander nicht berühren, entsteht kaum Verschleiß; die Pumpe läuft über lange Zeit mit gleichbleibender Leistung.
- Ölgeschmiert (etwa GHS VSD⁺): Öl dichtet und kühlt, ein mehrstufiger Abscheider hält es im Kreislauf.
- Trocken (etwa DRYVAC, NOVADRY, COBRA): kein Öl im Schöpfraum – für Prozesse, in denen Öl nicht erlaubt ist.
In der Zentralanlage
Warum die Grundlast eine Schraubenpumpe ist
Drehzahlregelung
Die Pumpe liefert genau das Saugvermögen, das die laufenden Maschinen brauchen – in unserer Referenzanlage ein Drittel bis die Hälfte weniger Energie.
Dauerbetrieb
Berührungsfreie Rotoren, geringer Verschleiß, lange Wartungsintervalle.
Großes Spektrum
Von 467 bis über 5.000 m³/h in einer Baureihe – eine Zentrale wächst mit der Produktion.
Kombinierbar
Mit Wälzkolben-Boostern für das Feinvakuum, mit Pufferbehältern für Lastspitzen.
