Download recommendations for circulation pumps (pdf)

The most energy efficient circulator pumps (class A) have a variable speed drive and a permanent magnet motor. In order to increase the efficiency of the circulation system, circulator pumps should not only be of class A, but also be correctly sized. Most installed pumps are oversized. The electricity saving potential across the EU-27 is more than 30 TWh per year. Starting in 2013, inefficient pumps will be phased out in the EU.
