Pumps - Rotodynamic pumps - Minimum required efficiency of water pumps and determination of Minimum Efficiency Index (MEI)

This document specifies performance requirements (methods and procedures for testing and calculating) for determining the Minimum Efficiency Index (MEI) of rotodynamic glanded water pumps for pumping clean water, including where integrated in other products.
The pump types and sizes covered by this document are described in the Annex A. These pumps are designed and produced as duty pumps for pressures up to 16 bar for end suction pumps and up to 25 bar for multistage pumps, for all pumps designed for fluid temperatures between −10 °C and +120°C. Also covered are 4" (10,16 cm) and 6" (15,24 cm) submersible multistage pumps designed for fluid temperatures between 0 °C and 90 °C.

Pumpen - Kreiselpumpen - Geforderte Mindesteffizienz für Wasserpumpen sowie Bestimmung des Mindest-Effizienzindexes (MEI)

Dieses Dokument legt Leistungsanforderungen (Methoden und Verfahren zur Prüfung und Berechnung) zur Bestimmung des Mindest-Effizienzindex (MEI) von Wasserpumpen in Kreiselpumpenbauart mit Stopfbuchsen zum Pumpen von sauberem Wasser einschließlich von Produkten, in welche diese Pumpen integriert sind, fest.
Die Pumpentypen und Pumpengrößen, die von diesem Dokument abgedeckt sind, werden im Anhang A beschrieben. Diese Pumpen werden als Pumpen für Drücke bis 16 bar bei Pumpen mit axialem Eintritt und bis 25 bar bei mehrstufigen Pumpen und bei allen Pumpen für Mediumtemperaturen zwischen −10 °C und +120 °C ausgelegt und hergestellt. Ebenfalls abgedeckt sind mehrstufige Tauchpumpen der Größe 4″ (10,16 cm) oder 6″ (15,24 cm) für Mediumtemperaturen zwischen 0 °C und 90 °C.

Pompes - Pompes rotodynamiques - Rendement minimal requis des pompes à eau et détermination de l'Indice de rendement minimal (MEI)

Le présent document spécifie les exigences de performance (méthodes et modes opératoires d’essais et de calculs) pour la détermination de l’indice de rendement minimal (MEI) des pompes à eau rotodynamiques dotées d’un dispositif d’étanchéité employées pour pomper de l’eau propre, y compris les pompes intégrées dans d’autres produits.
Les types et les gammes de pompe visés par le présent document sont décrits dans l’Annexe A. Ces pompes sont conçues et fabriquées comme des pompes de service pour des pressions inférieures ou égales à 16 bar pour les pompes à aspiration en bout et inférieures ou égales à 25 bar pour les pompes multi-étagées, pour toutes les pompes conçues pour des températures de fluides comprises entre -10 °C et +120 °C. Sont également couvertes les pompes multi-étagées de 10,16 cm (4") et 15,24 cm (6") pour les pompes submersibles multi-étagées à des températures de fluides comprises entre 0 °C et 90 °C.
