Use
Due to the two integrated operating modes „∆p regulation“ and „fixed rpm“ the pump can be adjusted very easily to the requirements of the particular application. Therefore it is not only suitable for heating systems but also for drinking water systems and industry installations. An extremely low power consumption is guaranteed because of the permanent magnet technology. In heating systems it fulfills already the even more tightened Ecodesign regulations ErP set for August 2015 today.
The HEP Plus (N) is available from now on in DN 25 and DN 15 and offers all features of the already known HEP Plus, like e.g. connection plug, display which shows power consumption in real-time, full ceramic bearings, air-vent screw and 5 years warranty.
 
For OEM applications the HEP Plus (N) is also available with switchable PWM inputs.
