Permanent magnet motors save money
Pumps are everywhere but it is easy to forget that they use energy, a lot of it!
Improving the efficiency of these pumps can add up to real savings in the amount of energy used.
In 2005 the voluntary energy labelling scheme for glandless circulators was launched and adopted by all the major manufacturers including, of course SMEDEGAARD.
The most important method of energy saving is to match the duty of the pump to the required duty; this is achieved by the integration of variable speed control in the design and construction of the pump. Indeed, all ‘A’ rated glandless circulators, including those offered by Smedegaard, are of this design. Figures from the BPMA (British Pump Manufacturers Association) suggest energy savings of up to 80% can be achieved by the correct selection of such a pump, when compared to standard induction motor pumps.
However, even further improvements can be achieved. Smedegaard has recently launched the SimFlex ‘A’ range of glandless circulators which enjoy all the advantages of variable speed control but now also include permanent magnet technology thus making the motors even more efficient so saving even more energy.
