Circulation pump for hot or cold water with in-line connectors, suitable for direct installation to pipes in civil and industrial heating, conditioning, cooling and domestic water systems.
Particularly versatile thanks to the use of the HYDRODRIVER, it offers performance features that can automatically adapt to the various system requirements whilst keeping differential pressures constant.
Pump body and motor support in cast iron. Cast iron impeller for all models from CME 65 to CME 150; in technopolymer for models from CM 40 to CM 50. Flanged suction and delivery connections in PN 16 with threaded holes for control pressure gauges. Mechanical seal in carbon/ceramic. Closed, asynchronous motor with external ventilation. Rotor mounted on oversized ball bearings to ensure silent running and long life. Built to IEC 2-3 standards Protected to: IP 55 Insulation class: F Standard voltage: single-phase 208-240 V / 50-60 Hz three-phase 380-480 V / 50-60 Hz Adjustment unit directly mounted on the electric pump that, by using the signal of the standard differential transducer, already connected and ready to use, modulates the speed of rotation in order to keep the differential pressure of the system on which it is constant used.
