Abstract

A pump and a method for operating a pump is proposed for mounting an impeller, which is inexpensive, free from contact and wear and thus extremely permanent. For this the invention uses a combination of permanent magnetic bearings and flow-mechanical bearings. The mounting is thus based on purely passive elements without using actively controlled and/or regulated elements.
