What is meant by ErP?
High energy consumption = high savings potential
ErP is the abbreviation for "Energy-related Products", which are products with high energy requirements – but also a high savings potential.
The ErP regulations were imposed with the aim of reducing this energy consumption. They establish the minimum energy efficiency requirements that products must meet.
What do the ErP regulations require?
More energy efficiency by 2020
Until 2020, the requirements for the efficiency of energy-consuming products will gradually become stricter – until the 20/20/20 targets have been achieved. This means:
| 20 % fewer greenhouse gases |
20 % more renewable energies |
20 % less energy consumption |
From 2013, only products that meet the minimum requirements of the ErP regulations may be placed on the market. These include:
- Circulators
- Standardised water pumps
- Electric motors (regulation in force since 2011)
Minimum requirements of the ErP regulations:
Water pumps
Circulators
Motors
Why is KSB ahead of its time?
High-efficiency products – ErP 2015 ready
KSB is well ahead of its time regarding the strict requirements of the ErP regulations. The standardised water pumps and circulators already meet the 2015 ErP regulations. KSB SuPremE® – the world’s most efficient magnet-less pump motor – exceeds even the 2017 ErP regulations.
How do ErP and FluidFuture® complement each other?
Discover potential energy savings
The ErP regulations play an important role in saving energy at component level. The main aim, however, is to improve the overall efficiency of your plant.
That’s why KSB uses the FluidFuture® energy efficiency concept to analyse and optimise the entire hydraulic system and to maximise its savings potential. Put more simply: it helps you to save money.

Glossary
IE codes
The "international efficiency" value indicates the efficiency class of motors. The higher the figure is, the higher the efficiency is. The classification ranges from IE1 (standard efficiency level) through to IE4 (super premium efficiency level).
MEI
The "minimum efficiency index" is a dimensionless scale unit for water pumps which specifies how many pumps have an inferior efficiency. An MEI of 0.4 means that 40 % of the pumps available on the market have an inferior efficiency. So the higher the MEI value, the better.
EEI
The "energy efficiency index" applies to circulators and specifies by how much the power input of the pump lies below a predefined reference power input. An EEI of 0.27 means that the circulator requires only 27 % of the power input that has been defined as the critical threshold. So a low EEI means that the pump has low energy consumption.
