Ecodesign

Our chance for the future: the Ecodesign Directive

With the Ecodesign Directive, the European Union is promoting climate protection by prohibiting the operation of power-guzzling products. This spells the end of inefficient pumps.

High-efficiency pumps provide huge savings potential!
Did you know that ...

  • approx. 50 TWh of electricity are consumed annually in pump applications in Germany (corresponding to 11% of gross annual electricity production)?
  • electric motors are responsible for 64% of total electricity consumption, 30% of which are consumed by pumps (Fraunhofer Institute)?
  • an economical savings potential of 15 billion kWh per year would result with optimization of pump systems used in Germany (corresponds to an equivalent of 10 million t of CO2 or a savings effect of EUR 1.2 billion at 8 cents/kWh)?
  • the energy-saving potential of pumps and pump systems is 30% (significantly higher in individual cases)?

Pumps are among the largest electricity consumers in industrial processes. To tap into their actual potential, motors and pumps on one hand and the entire pump system on the other hand must be considered under an energetic point of view. Whoever wants to promote efficient and energy-saving measures in the long term must optimize his overall system, i.e., motor, drive, pump, lines and fittings. We support you with our 6-point program for energy saving.

The EU Ecodesign Directive

The aim of this directive is to reduce energy consumption especially in high consumption products, including electric motors and water pumps. The implementation of the directive eliminates products with poor efficiency from the market. The European Union's Ecodesign Directive (Directive 2009/125/EG) establishes a framework to set mandatory ecological requirements for energy-related products (Energy-related Products, ErP). It replaces Directive 2005/32/EG of July 6, 2005, which is also called the Energy-using Products (EuP) Directive. Due to this directive, numerous energy-related products were examined and minimum requirements specified. As a result, environmental design requirements for electric motors and centrifugal pumps for pumping clean water have been specified in the EU Directive. This means both for manufacturers as well as for dealers that only products that meet these requirements may be sold on the market in the area of the European Community. All OSNA products, provided that they are covered by this EU Directive No. 547/2012 of June 5, 2012, meet the requirements of the minimum efficiency index ≥ 0.40 and are marked on this homepage correspondingly with the ERP2015 lo


The following types of pumps are covered by the directive:

  • Water pump with axial entry, own bearing (ESOB)
  • Water pump with axial entry, block design (ESCC)
  • Block water pump with axial entry, inline version (ESCCi)
  • Multistage vertical water pump/centrifugal pump (MS-V)

(Applicable only for pumps designed for a pressure of up to 25 bar and having a rated speed of 2,900 min-1 and a maximum flow rate of 100 m/h!)

  • Multistage submersible water pump/multistage underwater pump (MSS)

(Applicable only to water centrifugal pumps with an outer nominal diameter of 4" or 6", which are designed for operation in a borehole at operating temperatures between 0 °C and 90 °C and with a rated speed of 2,900 min-1!)

For pumps

EU Directive No. 547/2012 of June 5, 2012 on ecodesign requirements for centrifugal pumps for pumping clean water.

Directive (EU) No. 547/2012

 

For electric motors

EU Directive No. 640/2009 of July 22, 2009 and 4/2014 of January 6, 2014 specifying ecodesign requirements for electric motors.

The new IE efficiency classes of the motors replace the old EFF classes. Motor efficiency classes IE1, IE2, IE3 and IE4 are now defined with increasing efficiency rates.

As of January 1, 2017, all electric motors with a rated power of 0.75 to 375 kW must have a minimum efficiency rate of IE3, and IE2 motors may only be used in conjunction with speed control.
