New water pump regulations

The new regulation EC 547/2012 establishing the eco-compatible design for water pumps, was published in June 2012. This regulation is part of a much larger European Community project for the reduction of energy consumption. Water pumps are classified as part of electric motor systems. The overall potential for better energy saving for these systems is measured at about 20%-30%. One of the factors contributing to this energy saving, is the use of low energy consumption pumps. The preparatory study highlighted that water pumps are commercialised in large quantities within the European Community. Their consumption during the usage phase is the most important environmental aspect in its life cycle, it was estimated that in 2005 that the annual consumption of energy linked to the use of electric industrial water pumps was equal to 109 TWh. In the absence of any measures of control, it can only be predicted that energy consumption will increase to reach up to 136 TWh in 2020. The regulation has been prepared by the European Community and favours the introduction of technology which will decrease the impact of pumps on the environment during their life cycle. The adoption of these measures will mean an estimated energy saving of 3.3 TWh by 2020 Which pumps are covered in this regulation? End suction own bearing (ESOB) pumps for pressures up to 16.0 bar, with a shaft power of 150 kW, a maximum head of 90 metres and at a nominal speed of 1450 rpm or maximum head of 140 metres at a nominal speed of 2900 rpm.
