EAN Number: 5715121365765
Vertikale, mehrstufige Kreiselpumpe mit gegenüberliegenden Saug- und Druckstutzen (Inline-Bauweise). Die medienberührten Bauteile der Pumpe sind aus Grauguss (Kopf und Fusstück) und Edelstahl. Eine eingebaute Vorrichtung zum Axialschubausgleich nimmt hydraulische Axialkräfte auf und ermöglicht so die Verwendung eines Normmotors. Die Patronendichtung von Grundfos sorgt für eine hohe Betriebssicherheit und sichere Handhabung. Zudem erleichtert sie den Zugang bei Wartungs- und Reparaturarbeiten. Die Kraftübertragung erfolgt über eine starre, geteilte Kupplung. Der Rohrleitungsanschluss erfolgt über kombinierte DIN-Flansche. Die Pumpe ist mit einem 3-phasigen, lüftergekühlten Asynchronmotor ausgestattet.
