Technische Informationen im Überblick

tech-pumpeDUDEK-Zahnradpumpen werden für die unterschiedlichsten Aufgaben in Industrie und Chemie eingesetzt. Die Zahnradpumpen sind selbstansaugend und können unter bestimmten Voraussetzungen das Medium auch aus dem Vakuum fördern. Sie gehören zur Gruppe der Verdrängerpumpen und können mit unterschiedlichen Drehzahlen innerhalb bestimmter Spezifikationsgrenzen betrieben werden.

Die ausgebrachte Fördermenge ist quasi proportional zur jeweiligen Drehzahl, jedoch abhängig von Differenzdruck, Drehzahlniveau und Viskosität. Zur Vermeidung von Schäden an Pumpe und Anlage werden die Pumpen im Standard mit einem Druckbegrenzungsventil angeboten. Eine Beheizung der Pumpe ist optional ebenfalls möglich. DUDEK-Zahnradpumpen haben jeweils zwei außenverzahnte Zahnräder mit Schräg-, Pfeil- oder Geradverzahnung. Die Zahnradwellen sind in innenliegenden Gleitlagern gelagert, die vom Fördergut geschmiert werden. Je nach Anforderungen stehen verschiedene Lagermaterialien zur Verfügung. Für besonders abrasive Flüssigkeiten werden auch außengelagerte Varianten mit Wälzlagern angeboten. In Abhängigkeit vom Anwendungsfall wird die passende Wellendichtung ausgewählt. Die Pumpen können mit Magnetkupplung, innen- oder außenliegender Gleitringdichtung, doppeltwirkender Gleitringdichtung oder Stopfbuchspackung sowie den ggfs. notwendigen Überwachungs- und Sperrsystemen geliefert werden.

Die Pumpengehäuse werden in Grauguß, in Sphäroguß und in verschiedenen Edelstählen (auch Hastelloy) ausgeführt, das Material der Zahnräder und Wellen entsprechend in Stahl oder Edelstahl.

  • Betriebstemperaturen bis 270 °C, auf Anfrage auch höher.
  • Differenzdrücke 16 bar und 25 bar.

Die Pumpen können im Bereich explosiver Gas-Atmosphäre Zone 1+2 betrieben werden. Für diesen Zweck erhält die Pumpe eine gesonderte Konfiguration und erfüllt damit die Bedingungen der EG Richtlinie 94/9 Zone 2 II 3G und Zone 1 II 2G, (bzw. ab 20.04.2016 die EU Richtlinie 2014/34/EU). Generell erfüllen die DUDEK Pumpenaggregate die Maschinenrichtlinie 2006/42/EG und werden für EU-Kunden mit CE Kennzeichen geliefert. Die Informationen zu den Einsatzgebieten entnehmen Sie bitte den einzelnen Rubriken oder der Liste der Fördermedien. Für Fragen stehen Ihnen die Ansprechpartner gern zur Verfügung.
