Energy saving circulating pumps with flanges Construction Energy saving variable speed circulating pump driven by a permanent magnet synchronous motor (pm) controlled by on board inverter. Applications Heating, conditioning, circulating systems. For civil and industrial applications. Operating conditions - Liquid temperature from -10 °C to +110 °C - Ambient temperature from 0 °C to +40 °C - Maximum permissible working pressure: 6/10 bar - Storage: -20°C/+70°C max. relative humidity 95% at 40 °C - Certifications: in conformity with CE requirements - Sound pressure ≤ 54 dB (A). - Minimum suction pressure: - 0,5 bar at 50 °C. - 0,8 bar at 80 °C. - 1,4 bar at 110 °C. - Maximum glycol quantity: 20%. - EMC according to: EN 55014-1, EN 55014-2 EN 61000-3-2, EN 61000-3-2. - Connections: Flanges according to PN 6/10, EN 1092-2, DN 50, 65, 80, 100. - The benchmark for most efficient circulators is EEI ≤ 0,20. Synchronous motor with permanent magnet. - Motor: variable speed - Standard voltage: single-phase 230 V (-10%;+6%) - Frequency: 50-60 Hz - Protection: IP 44 - Insulation class: H - Overload protection (integrated). - Cable: phases and neutral. - Constructed in accordance with: EN 60335-1, EN 60335-2-51. Version DN ports in mm With flanges Max. head in dm connection size mm Features Smart pump NCE G.F adapt its functions to the system: the circulator measures the pressure and the flow and adjusts the speed to the selected pressure. Easy use There are different operating modes selectable from the control

Energy saving circulating pumps with flanges Operating modes Automatic mode (factory setting): In this mode the pump automatically sets the operating pressure, depending on the hydraulic system. This mode is recommended in most systems. Proportional pressure mode: The circulator changes the pressure propotionally to the current flow. The pressure value can be adjusted with the + and - buttons. Constant pressure mode: The circulator mantains the pressure constant when the reference flow changes. The pressure value can be adjusted with the + and - buttons. Operating mode-control panel Fixed...
