Pumps - Methods of qualification of the Energy Efficiency Index for rotordynamic pump units - Part 3: Testing and calculation of energy efficiency index (EEI) of booster sets

Edition date: 2026-09-16
In Force
Available languages: English, French
Summary: This document specifies methods and procedures for testing, calculating and determining the energy efficiency index (EEI) of booster sets. A booster set is either a single pump unit or an assembly of pump units connected in parallel with a maximum hydraulic power of 150 kW, a minimum rated flow of 6 m3/h (0,001 667 m3/s), operated with backflow prevention and additional components influencing hydraulic performance and with components necessary to control pressure or provide flow in open loops inside buildings and which is placed on the market and/or put into service as one single product and its intended use is to pump clean water and does not have a self-priming functionality. A booster set with a rated flow below 6 m3/h is composed using pumps that comply with EN 17038 2.

Le présent document spécifie les méthodes et procédures d’essai, de calcul et de détermination de l’indice de rendement énergétique (EEI) des groupes de surpression. Un groupe de surpression se présente sous la forme soit d’un groupe motopompe individuel, soit d’un assemblage de groupes motopompes raccordés en parallèle avec une puissance hydraulique maximale de 150 kW et un débit nominal d’au moins 6 m³/h (0,001 667 m³/s), destiné à être utilisé avec un disconnecteur hydraulique et des composants supplémentaires influençant les performances hydrauliques, ainsi qu’avec les composants nécessaires pour contrôler la pression ou assurer un écoulement dans les boucles ouvertes à l’intérieur de bâtiments, et qui est commercialisé et/ou mis en service en tant que produit individuel conçu pour le pompage d’eau propre et sans fonctionnalité d’auto-amorçage. Un groupe de surpression avec un débit nominal de 6 m³/h comprend des pompes conformes à l'EN 17038 2.

Dieses Dokument legt Methoden und Verfahren zur Prüfung, Berechnung und Bestimmung des Energieeffizienzindex (EEI) von Druckerhöhungsanlagen fest. Eine Druckerhöhungsanlage ist entweder ein einzelnes Pumpenaggregat oder eine Baugruppe parallel geschalteter Pumpenaggregate mit einer maximalen hydraulischen Leistung von 150 kW, einem Mindestnennförderstrom von 6 m3/h (0,001 667 m3/s), die mit einem Rückflussverhinderer und zusätzlichen, die hydraulische Leistung beeinflussenden Bauteilen sowie mit Bauteilen, die zur Druckregelung oder zur Bereitstellung des Förderstroms in offenen Kreisläufen innerhalb von Gebäuden erforderlich sind, zu betreiben ist und die als ein einziges Produkt in Verkehr gebracht und/oder in Betrieb genommen wird und deren bestimmungsgemäße Verwendung die Förderung von sauberem Wasser ist und die keine selbstansaugende Funktion hat. Eine Druckerhöhungsanlage mit einem Nenndurchfluss von weniger als 6 m3/h muss aus Pumpen bestehen, die der Norm EN 17038 2 entsprechen.
