Abstract

A circulation pump assembly for a heating and/or cooling system includes an electric drive motor () and a connected pump housing () in which at least one impeller () is situated and which comprises a first inlet () and a first outlet (). The pump housing () includes a second inlet () which is connected in an inside of the pump housing () at a mixing point () to the first inlet (). A regulating valve (), which is designed for regulating the mixing ratio of two flows mixing at the mixing point (), as well as a control device, which controls the regulating valve () for regulating the mixing ration, are arranged in the pump housing (). A hydraulic manifold is provided with such a circulation pump assembly.
