Abstract

Die Erfindung betrifft eine Pumpe mit im oder am Pumpengehäuse integrierter Leistungsregelung, wobei in Abhängigkeit der Temperatur des Fördermediums der von der Pumpe einzuhaltende Differenzdruck eingestellt wird, wobei der Regelungszusammenhang zwischen der Temperatur des Fördermediums und dem von der Pumpe einzuregelnden Differenzdruck einer monoton fallenden Funktion entspricht.
