The EuP motors on

The EuP motors on

Pumps consume 10% of world’s electrical power and without them we would have no hot water, heating or air conditioning, nor could we access clean water or dispose of wastewater. Manufacturing and the process industries would also grind to a halt without a range of pumps that literally keep the wheels of industry turning.

However all this comes at a cost, more especially as the vast majority of pumps are both oversized and don’t incorporate the most efficient motor technologies, which when fitted, can mean a whopping 80% energy reduction over less efficient models.

In 2005 the EU recognised this and introduced the Energy Using Products (EuP) directive that focussed on goods that used, generated or transferred energy. The objective at that time was to encourage the widest use of improved energy efficiency equipment as an important contributor to achieving EU emissions targets.

EuP or ErP:

The directive has been under review more recently and its scope was broadened to include Energy Related Products (ErP) to encompass goods that impact on energy consumption during use. This new Commission Regulation EC 640/2009 now specifies the ecodesign requirements for electric motors which includes glandless standalone circulators as well as glandless circulators that are integral within other products. This change followed a preparatory study that looked at technical, environmental and economic analysis of motors and motor drives.

Important deadline

What all this means for the pump industry – as well as the wider community  is that from 1 January 2013 this directive will determine the minimum efficiency requirements with regard to standalone circulators. The main goal of this new directive is to improve the life-cycle environmental impact of electric motors, that is expected to lead to the following estimated savings in 2020:

  • LCC energy savings of 5,500 PJ (1 TWh=3.6 PJ)
  • Electricity savings of 135 TWH

So this means that from next year glandless standalone circulators, with the exception of those specifically designed for primary circuits of thermal solar systems and of heat pumps, will need to have an energy efficiency index (EEI) of not more than 0.27. With other ever stricter changes scheduled to take place in 2015 and 2020.

Motoring on

Motors are also in focus and in order to simplify the various current national standards that exist for motors, a new IE standard (International Efficiency class) has also been adopted:

  • IE1 = Standard efficiency (comparable to EFF2)
  • IE2 = High efficiency (comparable to EFF1)
  • IE3 = Premium efficiency.

So pump energy efficiency legislatively is here to stay and at Grundfos we have a range of EuP ready products and super energy efficient BLUEFLUX motors that all meet the most stringent demands that not only already meet the legislative demands that come into force in 2013 but also those that will come into force two year later in 2015.

Installing energy efficiently is one of the genuine ‘win, win’ situations we can all benefit from, so whether you are a bill payer or believe in conservation, selecting an ‘A’ rated pump is something that will soon be obligatory. But why wait for the enforcement of this EuP directive to make the change, why not do it today, as these more efficient pump products are available right now.
