Aus vielen Jahren der Anwendungserfahrung in der Abdichtung von Hydraulikgeräten, die durch die Ergebnisse umfangreicher Testprogramme gestützt wird, wissen wir, dass die drei Hauptbetriebsindikatoren Geschwindigkeit, Druck und Temperatur miteinander zu verbinden sind, um die beabsichtigte Dichtleistung zu erzielen.
Nach sorgfältiger Analyse aller Produkte sind wir in der Lage, die maximale Geschwindigkeit und den maximalen Druck innerhalb eines Temperaturbereichs zu spezifizieren, mit denen die Dichtung sicher arbeiten kann. Wenn die Betriebsbedingungen nicht den empfohlenen Werten entsprechen, senden Sie Ihre Spezifikationen an Ihr lokales Hallite-Verkaufsbüro. If your operating conditions do not comply with those recommended please send your details to your local Hallite sales office.
