Preassembled pump group for direct distribution or circulation. Allows the circulation of the thermal fluid, coming from the primary circuit, without performing any thermal regulation. It is used when the same flow temperature of the primary circuit is requested by the user in general heating/cooling systems and radiant panel systems. The group is composed of a pump, flow LCD thermometers, manual air vent, fittings for secondary distribution manifolds. The group can be installed with the secondary distribution manifolds on the right or the left. The offset fitting on the flow pipe allows the installation of the group in a perfect vertical position and the coupling to manifolds with different centre distances.
