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.

Figure 00000001
The invention relates to a pump with power control integrated in or on the pump housing, the differential pressure to be maintained by the pump being set as a function of the temperature of the pumped medium, the control relationship between the temperature of the pumped medium and the differential pressure to be regulated by the pump corresponding to a monotonically falling function.
