* Die max. Fördermenge ist ein ermittelter Wert mittels Prüfstand und gemessen mit Wasser bei einer Mediumstemperatur von ca. 20° C. Die Messung erfolgt am Druckstutzen der Pumpe, ohne Schlauch, Zapfpistole oder Durchflussmesser. Die im Einsatz erzielbare Fördermenge ist niedriger und hängt von der individuellen Anwendung, den Medieneigenschaften sowie der Konfiguration der Pumpe ab. Die max. Förderhöhe ist ebenso abhängig von Pumpenausführung, Motor und Medium. Die Viskositätswerte werden mit Öl ermittelt.

** Prüfaufbau: Medium Wasser / Diesel, Durchfluss in Vorzugsrichtung, Beruhigungsstrecke 0,2 m vor und nach dem Durchflusszähler
