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 venting and unblocking routines.
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 curves.
