Abstract

The difficult transfer of EC motors into wet runner technology has been solved with the Wilo-Stratos range. Canned pumps with EC motor enable high efficiency for the design point of the pump compared to pumps with asynchronous motor.

The difference in efficiency between these motor types increases for decreasing motor power.

Beside the improvement of the best point efficiency, EC motors are characterized by an excellent part load behavior. This feature is very important for pumps used in building applications, since the pumps are operated mainly in part load conditions. A comparison between pumps realized with asynchronous and EC motors applying simulated load profiles show significant differences in power consumption.

Transferring these results to the above mentioned quantity of pumps installed in Europe in heating applications we can estimate an energy saving potential of more than 20 TWh/a, assuming that all pumps would be realized in EC motor technology. Therefore a significant economical and ecological effect could be achieved.
