Description
Flüssigkeitsringpumpe
Als weitere Maßnahmen zur Schalldämmung eignen sich grundsätzlich sind fest in den Pumpendeckel eingegossene Geräuschrippen oder speziell sekundär wirkende Schalldämpfer. Dabei bewirkt die Geräuschrippe in vielen Fällen eine unzureichenden Schalldämmumg. Spezielle Schalldämpfer vergrößern das Bauvolumen der Pumpe und erhöhen die Herstellungskosten.
