Pumps can save millions of tonnes of CO2

now – pumps and motors provide a massive opportunity

Now the world has recognised the reality of climate change, countless new ways are being developed to fight it. It is usually those that are easiest to understand that capture the most attention. Yet many of them, however promising, will take time to fulfil their potential.

That is why, while we strive for new technologies, we must also examine the technologies we already have. We must seek out solutions that can create both substantial, and immediate, CO2 reductions. In sum, we need to make sure that what we have uses less energy.

To secure the future, we should commit to efficiency now – and pumps and motors provide a massive opportunity. In 2011, a new EU – EuP, Energy using Products – directive, will come into effect and set out radical requirements for motor efficiency. This will lead to electricity savings of 135TWh in the EU by 2020. Leading pump manufacturer, Grundfos, with an annual production of more than 16 million pumps, explores further.

Pumps keep our world turning

Accounting for 10% of all power consumption, the importance of pumps cannot be underestimated; they are found literally everywhere. From the water we drink, heat and wash with, to the food we eat and the production of all the goods we buy, they are always involved. There is an endless list of applications; wherever liquid of any form needs to be moved, pumps are an absolute necessity.

Switching to high-efficiency motors on all pumps would significantly reduce this figure – and the technology already exists. Motors that bear the EFF1 designation operate at higher levels of efficiency than the majority of motors installed today. Grundfos already provides EFF1 motors as standard on in-line pumps.

For even greater energy savings, of up to 60%, an EFF1 motor can be used in conjunction with a frequency converter. This intelligent technology regulates the motor speed constantly, in direct response to the system needs, meaning the motor never uses more energy than required.

  • Pump motors use 259TWh a year in the EU
  • 163TWh of this is from industry, 46TWh from the tertiary sector, and 50TWh from the residential sector.

Setting the efficiency standard

Grundfos was actively involved in the creation of the 2005 European energy-labelling scheme for residential heating circulators. They were one of the first to bring A-labelled circulators to market which made it easier for homeowners throughout Europe to both save money and reduce their environmental impact.

A-labelled circulators use up to 80% less energy than standard or D-labelled models. There are still around 100 million D-labelled circulators installed in Europe, but within three years’ time, it will be mandatory to replace them with more efficient models for these reasons:

  • From 2013, standard efficiency circulators will be prohibited. As from 2015, A-labelled circulators will be the only choice;
  • Replacing a D-labelled circulator with an A-labelled one can cut 10% off the average household’s energy bill; and,

The A-labelled Grundfos ALPHA2 circulator can operate on as little as
five watts.

About Grundfo
Founded in 1945, the Danish company, Grundfos, consists of 82 companies in 45 countries.

It produces circulator pumps for heating and air-conditioning and centrifugal pumps for industry, water supply, wastewater and dosing.

Grundfos is also the world’s biggest manufacturer of energy efficient motors and the leading producer of frequency converters for pump applications. In 2009, it invested around EUR130 million in research and development.
