Obviously, the first and most straightforward feature of EuroDEEM 2000 is the updating of the motor catalogue with new data supplied by manufacturers. (last date input March 2003)
Also the number of manufacturers is increased.
During year 1999 the European Motor Manufacturer Association CEMEP and the European Commission (DG TREN) reached an agreement on the definition of EFFICIENCY CLASSES.

EuroDEEM assigns to motors the efficiency class, determining it by comparison with motor efficiency data supplied.
However only the motor manufacturers partecipating in the CEMEP agreement are authotized to use the efficiency class EFF1, EFF2 and EFF3 logo on motors catalogue.
Calculation of energy consumption requires the availability of the curve of efficiency as a function of the Load.
For old motors part load efficiency values not always are available. Also some catalogue of new motors do not quote the efficiency for load values below 50%. In some cases manufacturers had supplied only the efficiency at nominal power.
A new interpolation formula has been adopted in EuroDEEM, which allows to obtain the efficiency curve, knowing only one efficiency value of the curve. The formula is based on conservative criteria.
Major development had been focused on end-use devices, starting from pump devices.
The European Commission believes that improving the efficiency of pump systems is important - and this is addressed by the study conclusions, EuroDEEM and the Europump/HI LCC Guide.
The JRC has developed and implemented both the pump database and the related pump module, which allows the user to analyse the working point of a pump and to assess how efficiency conditions could be improved.
For the time being, it was not possible to load the pump data into the pump database.
The pump module had been developed according to 3 development levels:
A "fast & easy" type/application selection tool
- The module permits the user to find a list of manufacturers that produce pumps that match a specific pump type or application. It will help in getting quotes for the comparison to the procurement line.
- The output of the query gives a list of manufacturers, each with a list of pumps together with their description (type and application, head and flow ranges, drive type, construction materials, national distributors, web links, email, etc.)
The idea behind this option is to have all possible pump types manufacturers and their pumps in the database in order to let the end user to look-up for manufacturers that produce a specific pump type or for a specific application within a specific range of head and flow to get the quote.
No energy analysis is done at this stage.
LEVEL # 2
Intermediate tool for selecting a pump according to the user's specifications
- The selection is based on Total Dynamic Head (TDH) and flow, static suction head, pump speed, pump application, pump type, and optional pump features.
- No energy analysis is yet done at this step, but pumps can be sorted out according to the Best Efficiency Point (BEP). Pumps are also ranked according to the Procurement Line.
This tool provides a list of manufacturers, each with a list of pumps together with their description (type and application, head and flow ranges, drive type, construction materials, national distributors, web links, email, etc.).
Advanced Pump Selection Tool
- This tool is based on the previous one, but is more complicated and sophisticated. The selection tool has to provide a list of most suitable and cost-effective pumps for a specific use. It must be capable of performing energy analysis, power requirements, and it must get linked to the motor and VSD database for suggesting possible energy saving measures.
- It requires from the end-user the description of the system driven by the pump, by means of design data such as TDH and flow (or system curve), NPSHA and static suction head, total static head, liquid, duty profile, pump speed, orientation, application, type, and optional pump features.
- The pump data required are usually already quoted and available in pump catalogues: Head at different flow points for various impeller size, Efficiency and power at different points, NPSH at different points, type of pump, applications, orientation, drive type, features, insulation class, materials, shaft seal, motor included, etc.
The goal of this application is to provide to the end-user a tool for Company Inventory management (pump replacement and/or energy saving opportunities through VSD, etc.), as well as a tool for selecting suitable and cost-effective pumps for a specific application.
As stated above, this EuroDEEM featured is, for the moment, not yet operational the Commission's proposal. Once an agreement will be reached both on the pump data set and analysis module, pump data will be gathered and the database will become operativehered and the database will become operative.
