Abstract
A multiple-pump device for a vehicle may include a housing. The housing may include at least a first drive device for driving a first drive shaft with a first impeller, and a second drive device for driving a second drive shaft with a second impeller. The multiple-pump device may include a bearing shield penetrated by the first drive shaft and the second drive shaft. The beating shield may separate a wet region with the first impeller and the second impeller from a dry region with the first drive device and the second drive device. The multiple-pump device may include power electronics arranged in the dry region and connected with the bearing shield to transfer heat.
