Abstract
In a fuel pump () designed as a side channel pump, in each case two conveying chambers (-) one surrounding the other concentrically are arranged on two impellers (). The conveying chambers () of one impeller () are connected to an inlet duct (), while the conveying chambers () of the other impeller () are connected to an outlet duct (). A connection () of the conveying chambers (-) is arranged in a partition () keeping the impellers () at a distance from one another. As a result, the fuel pump () has an especially high volume flow, along with a very high conveying pressure.
