Water companies and other users of pumps are being urged to ensure they are aware of tough new European Union (EU) carbon reduction regulations aimed due to come in to force next week.
Strict efficiency criteria
The Department for the Environment, Food and Rural Affairs is attempting to raise awareness of the new regulations.
They demand that most electric motors sold as new after 16 June meet strict efficiency criteria. Only submersible motors and those used in extreme environments are excluded. Water companies are major purchasers of motors for water pumps and are likely to be most affected.
The new EU regulation is part of its 2005 Ecodesign Directive which has progressively banned high energy products such as lightbulbs and refrigerators.
It is claimed that motors of all types, including those for water pumps, are responsible for around 40% of energy use in the EU, and around 12% of EU carbon dioxide emissions.
Focus on motors
The European Commission has calculated that the greatest opportunity for cutting the energy use of motors lies in life cycle energy consumption by improving the efficiency of the motor and the pump it powers.
Impacts from production and distribution are minor compared with the user-phase impact, it has calculated.
The commission estimates that the new regulations will lead to annual user-phase electricity consumption savings of about 139 TWh by 2020, close to Sweden’s the total annual energy consumption and corresponding to an annual reduction of 64M.t in CO2 emissions.
Pump manufacturers across the EU have been working to ensure their products comply.
“We have been restyling our pumps and their motors to have better efficiency, for example building internal parts that ensure less head losses and therefore giving energy savings,” said Alessandro Bertazzoni, international sales director for Italian pump manufacturer Saer.

Saer’s pumps are about to hit the UK market through an exclusive distribution deal with construction logistics firm Burdens.
In April Saer concluded a review of all its electric motors to ensure they comply with the regulations and aims to take advantage of publicity surrounding the new rules to highlight further efficiency improvements.
“We have changed some of our pump designs,” he said. This includes casting pumps from stainless steel, changing the thickness of impellers and adapting pump geometry.
