Abstract

Die Erfindung betrifft eine Doppelpumpe mit einer ersten Pumpe zur Erzeugung von kleineren Förderströmen Qkl bei vorgebbarem Differenzdruck zwischen der Pumpenansaug- und der Pumpenauslaßseite und einer zur ersten Pumpe zuschaltbaren zweiten Pumpe zur Erzeugung von größeren Förderstromen Qgr, und einer die beiden Pumpen steuernden Pumpensteuerung, wobei die Pumpensteuerung die Drehzahl der ersten Pumpe bis zum Erreichen eines bestimmten Förderstroms Q* kontinuierlich erhört, wobei bis zum Erreichen des bestimmten Förderstroms Q* die zweite Pumpe ausgeschaltet ist, und die Pumpensteuerung bei Erreichen des Förderstroms Q* die zweite Pumpe zur ersten Pumpe zuschaltet, und für alle Förderströme Q >= Q* (Q größer gleich Q*) beide Pumpen mit der gleichen Drehzahl fördern.
