Circulation pump assembly for a heating and/or cooling system

A hydraulic manifold and circulation pump assembly combination comprising:

• a circulation pump assembly comprising:
• a drive motor;
• at least one impeller;
• a pump housing connected to this drive motor, the at least one impeller being situated in the pump housing, the pump housing comprising a first inlet, an outlet and a second inlet which is connected in an inside of the pump housing at a mixing point to the first inlet;
• a regulating valve regulating a mixing ratio of two flows mixing at the mixing point, the regulating valve being arranged in the pump housing;
• and
• a control device controlling the drive motor and the regulating valve for regulating the mixing ratio;
• at least one load module connected to the pump housing, the at least one load module comprising a section of a feed conduit and/or a section of a return conduit, wherein the section of the feed conduit is connected to the first outlet of the pump housing and comprises a feed connection and the section of the return conduit is connected to the second inlet of the pump housing and comprises a return connection.
