Duca

Duca is a brand in the Supomp catalog offering circulation pumps. The Cosmo series variable-speed union-fit circulation pumps are available in different installation lengths and max. head options. Circulation pumps circulate water between the boiler, radiators, and underfloor heating pipes in closed-loop heating systems; variable-speed models adjust their speed to demand, reducing energy consumption. Expressions such as 25-8 and 180 mm in the product names refer to the connection size, maximum head, and installation length. When replacing an existing pump, matching the installation length and connection size allows a drop-in replacement without modifying the pipework. Remember to bleed the system on first start-up.
