Calpeda NCE EI Energy Saving Circulating Pumps
DOWNLOAD PRODUCT SPECIFICATIONS |
The Calpeda NCE EI 32-60 is a highly efficient, energy-saving variable speed circulating pump designed for small-scale domestic heating and underfloor systems. Engineered with a permanent magnet synchronous motor and integrated onboard inverter, this compact circulator intelligently adjusts to system demands—optimizing flow and reducing power consumption without compromising performance.
Housed in a robust cast iron body, the NCE EI features threaded ISO 228 ports (G1, G1½, G2) and delivers quiet, long-lasting operation even in tight installation spaces. This model is perfect for radiators, floor heating loops, and other closed-loop hot water systems where efficiency, compactness, and plug-and-play usability are key.
