Preassembled pump group for fixed point regulation and circulation of mixed fluid. Allows the circulation of the thermal fluid, coming from the primary circuit, by keeping the temperature at a pre-set value (fixed point) through the help of a mixing valve with thermostatic element. It is used in heating systems in general and radiant panel systems. The group is composed of a pump, flow/return shut-off valves, thermostatic mixing valve, flow/return temperature gauges, anti-thermosiphon check valve, thermal insulation. The 02G.DN25 series is fitted for the installation of a differential by-pass valve, while in the 32G.DN25 and 24G.DN25 series the differential by-pass valve can be installed only externally. The 24G.DN25 series is fitted for the installation of a 110 or 130 mm energy metering device. All the groups are reversible (the flow line can be exchanged with the return line).
