Designation NCE EI 32 - 60 / 180 Series Version DN ports in mm Max. head in dm connection size mm Special features on request Brass or cast iron unions. Features Compact design The space saving NCE EI is a very compact circulating pump, allows inr easy installation in small domestic heating systems. Easy to install and to adjust Installing the NCE EI is considerably simplified by the quick setting and power installation plug. Reliable Like all our electronic circulating pumps, the NCE EI features the patented self-cleaning square chamber design, which eliminates any possibility of rotor blockage. Ceramic shaft Hydraulics components are completely painted with cataphoresis. Program for automatic routine vent and release. Easy use Operating range with fixed curves from 0,5 m to 7 m; possibility to choose 2 (1-2) proportional pressure curves and 2 (I-II) constant pressure cu

Energy saving circulating pumps Operating modes PROPORTIONAL CURVE PROGRAMMING Ap-v Moving the switch to 1 or 2 setting, the pump operates with the proportional curve. This mode ensures maximum energy efficiency. CONSTANT CURVE PROGRAMMING Ap-c Moving the switch to I or II setting, the pump operates with a constant curve according to the - ^m selected flow rates. MANUAL PROGRAMMING Setting the switch in any position between the MIN and MAX points, the most suitable operating curve for the installation is manually selected. w - The red LED indicates that the pump is not rotating but is still...
