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 and conditioning systems. Operating conditions - Liquid temperature from +2 °C to +110 °C - Ambient temperature from 0 °C to +40 °C - Maximum permissible working pressure: 10 bar - Storage: -20°C/+70°C max. relative humidity 95% at 40 °C - Certifications: in conformity with CE requirements - Sound pressure ≤ 40 dB (A). - Minimum suction pressure: - 0,05 bar at 75 °C - 0,28 bar a 90 °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 32, 40, 50. - 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: F - Overload protection (integrated). - Cable: phases and neutral. - Constructed in accordance with: EN 60335-1, EN 60335-2-51. Series Version DN ports in mm With flanges Max. head in dm connection size mm Special features on request Additional module: - analog input 0-10V - remote on/off input - output relay Features Smart pump NCE H.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 p

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 speed...
