An elaborate study executed in the direction of exploring energy saving potential shows that more than 20% of electrical energy used in industry is used for pump systems. Experts calculate that more than 30% of this energy can be saved by improving control and diagnosis for pump systems. Unfortunately, the application ratio of such system is small and consequently a large demand for such technological advanced systems can still be observed in the pump industry. Because of this reason and still growing demand of saving energy in industry, two Universities in Germany and Switzerland together with leading German pump manufacturer decided to join their knowledge and skill to work on the project called "Smart Pump". This paper presents one of the first results of this project, which goal is the development of future control methods and diagnosis systems for intelligent pumps.

Zusammenfassung Der folgende Beitrag beschreibt die Entwicklung eines Modells von Dreispindelpumpen. Solche Pumpen werden heute in vielfältigen Anwendungsgebieten eingesetzt, z. B. in der Energieerzeugung. Das Modell dient der Simulation des Pumpensystems und soll in weiteren Schritten in vereinfachter Form in der Steuerung der Pumpe integriert werden, um fortgeschrittene modellbasierte Verfahren des Monitoring, der Regelung und Diagnose ermöglichen. Die Ergebnisse stammen aus einem gemeinsamen Projekt eines führenden Systemanbieters im Pumpembereich und dreier Hochschulen in Deutschland, Polen und der Schweiz.
