NCE High Efficiency Energy Circulating Pumps (n curves) 

Construction:

With the new NCE sereis calpeda wishes to introduce a new standard in domestic 
hot water circulating systems.
Only one high efficiency, energy saving variable speed circulating pump drived by a 
permanent magnet synchronous motor (pm) controlled by one on board inverter 
suitable for small domestic heating system.

Benefits
-energy efficiency class: A
-high savings 
-low consumption 
-n flat curves in a wide working area
-low noise
-easy adjustment of right working point 
-compact dimensions  
-self cleaning

Benefits to distribution
-only one circulating pump to use and install
-less transportation and logistic cost
-less spare parts requirement.
