By em. Dr.-Ing Bernd Stoffel

Assessing the strength potency of Pumps and Pump Units, built in cooperation with Europump, is the 1st booklet on hand supplying the historical past, technique, and evaluate instruments for knowing and calculating strength potency for pumps and prolonged items (pumps+motors+drives). Responding to new ecu requisites for pump potency, and US DOE exploratory paintings in surroundings pump power potency directions, this ebook offers rationalization, derivation, and representation of PA and EPA equipment for assessing strength potency. It surveys laws regarding pump power efficiencies, presents historical past on pump and motor efficiencies, and describes the idea that of strength potency Index (EEI) for circulators and unmarried and multi-pump systems.

  • The first ebook to hide Europump- subsidized learn on power potency in pumps, together with insurance of recent ecu instructions applied in January 2015
  • Discusses Product process (PA) and prolonged Product procedure (EPA) to assessing power efficiency

Example text

30] and Chapters 3 and 8). 2, the energy efficiency of pump units is relevant for the total (global or European) consumption of electric energy. Therefore, it is an ecological and political goal to reduce energy consumed by the use of pump units. In the EU, a legislative frame was established by a general directive concerning all energy using products (EuP) [11], also called the EcoDesign Directive. This directive allows the EC to develop measures to reduce the eco-impact of EuP within the EC.

After finishing the work done by Europump on the Product Approach (PA) for clean water pumps and on the concept of MEI, the activities of Europump, organized by the JWG, were focusing on the Extended Product Approach (EPA) for pump units. Because of the inclusion of electric components (motor or PDS) in the treatment of pump units as extended products, from the beginning of the work on this item experts from the side of motor, converter, and PDS manufacturers became regular members of the expert subgroups.

Technical Specifications of IEC are published when the subject under question is still under development and/or when insufficient consensus for approval of an international standard is available. Standardization and Legislation Chapter | 2 29 The new European Standard EN 50598 [15] is concerned with Ecodesign for power drive systems (PDSs), motor starters, power electronics, and their driven applications. It consists of three parts: ● ● ● Part 1: General requirements for setting energy efficiency standards for power-driven equipment using the extended product approach (EPA) and semi-analytic model (SAM) Part 2: Energy efficiency indicators for PDSs and motor starters Part 3: Environmental aspects and product declaration for PDSs and motor starters.
