20150132172 | MICROPUMP, BEARING ELEMENT FOR A MICROPUMP, AND WORKING METHOD - The invention relates to a micro pump, comprising an inner rotor arranged on a shaft and an outer rotor, which form a rotor unit including a delivery chamber for fluid, wherein the pump comprises a multi-functional bearing member for the shaft with improved lubrication, to a bearing member for a micro pump and to an operating method. | 05-14-2015 |
20130294940 | MAGNETICALLY DRIVEN PUMP ARRANGEMENT HAVING A MICROPUMP WITH FORCED FLUSHING, AND OPERATING METHOD - A technical problem (object) of the invention is to achieve a cost-effective construction of a pump arrangement comprising the micropump and to make do with a minimum number of components, which are of the simplest possible design in terms of production and which can be joined together in a precise manner in terms of assembly. In a particular aspect of the problem, complexity of production is to be replaced at least in part by complexity of assembly, whereby necessary close tolerances are also achieved. These are a sine qua non for microsystems and micropumps. In a further aspect of this problem, the micropump is also to be flushed or lubricated in the bearing region, which is a considerable problem at rotational speeds above 5000 rpm. For this purpose, a pump arrangement is proposed, comprising a magnetically drivable micropump (P) for pumping a liquid pumping medium and comprising a bearing carrier ( | 11-07-2013 |
