High efficiency wet rotor circulator pump with threaded or flanged fitting, permanent magnet motor and integrated electronic control. “Ego” is a cutting-edge range of high efficiency wet rotor electronic circulators that fully comply with European Directive ErP 2009/125/CE. All Ego circulators feature the ECM technology (electronically commuted motor with rotor equipped with permanent magnets), that enables automatic and continuous regulation of the pump (flow rate/head) depending on the actual requirements of the system, ensuring important energy savings. All models include inputs/outputs, analogic signal, ethernet connection, modbus communication and have a unique display to make them user-friendly. Ego are available in single or twin version, with threaded or flange fittings. Ego circulators are specifically designed for heating systems and circulation of liquids in air-conditioning systems. The pumps are suitable for single-pipe systems, two-pipe systems, underfloor heating systems and mixing loops of great installations. Some models are suitable for circulation at temperatures below 0°C (they are, therefore, particularly recommended for air-conditioning and/or refrigeration systems).
