Electronic in-line pumps for water circulation in conditioning and heating systems, water recirculation even where there are solar thermal panels (solar collectors) and for circulation of drinkable hot water in commercial building service. Pump body, motor support and fan cover are in cast iron. Impeller in cast iron or technopolymer depending on the models. The MCE-C variable frequency drive is installed as standard and allows the motor operating speed to be changed automatically based on the requests, protecting against water hammering and saving energy when compared to pumps or circulators without the variable frequency drive. The CM-GE version is equipped with a rigid joint. CME and CM-GE pumps are single pumps, those with DCME and DCM-GE codes are twin pumps. All models have a air-cooled four-pole asynchronous motor, flanged inlet and outlet ports. Cast iron pump body, stainless steel motor shaft. Possibility of remote control thanks to the DConnect service (DConnect Box supplied separately).
