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 heating systems. The group is composed of a pump, flow/return shut-off valves, shut-off valve at the pump inlet, flow/return temperature gauges, anti-thermosiphon check valve, thermal insulation. The 01G.DN25 series is fitted for the installation of a differential by-pass valve, while in the 31G.DN25 and 23G.DN25 series the differential by-pass valve can be installed only externally. The 23G.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).
