Pumps - Minimum required efficiency of rotodynamic water pumps

This European Standard 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 standard 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, temperatures between -10 °C and +120 °C and 4" or 6" size for submersible multistage pumps at operating temperatures within a range of 0 °C and 90 °C.
In addition, this standard specifies how the value of the Minimum Efficiency Index (MEI) of a pump size indicated by the manufacturer can be checked by market surveillance.
Even if it is left free to the manufacturer of a pump size how to prove the rated value of the Minimum Efficiency Index (MEI), nevertheless this standard specifies a method to prove that this rated value meets the requirements within the confidence intervals with a sufficiently high probability.

Pumpen - Geforderte Mindesteffizienz bei Kreiselpumpen für Wasser

Diese Europäische Norm 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 dieser Norm 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 für Temperaturen zwischen -10 °C und +120 °C und mehrstufigen Tauchpumpen der Größe 4" oder 6" bei Betriebstemperaturen in einem Bereich zwischen 0 °C und 90 °C ausgelegt und hergestellt.
Darüber hinaus legt diese Norm fest, wie der durch den Hersteller angegebene Wert des Mindest-Effizienzindex (MEI) einer Pumpengröße durch die Marktüberwachung verifiziert werden kann.
Selbst wenn es dem Hersteller einer Pumpengröße überlassen wird zu entscheiden, wie der Bemessungswert des Mindest-Effizienzindex (MEI) nachgewiesen wird, legt diese Norm dennoch ein Verfahren zum Nachweis fest, dass dieser Bemessungswert die Anforderungen innerhalb der Vertrauensintervalle mit einer ausreichend hohen Wahrscheinlichkeit erfüllt.

Pompes - Rendement minimum requis des pompes à eau rotodynamiques

La présente Norme européenne 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 la présente norme 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, des températures entre -10 °C et +120 °C et un dimensionnement de 10,16 cm (4"") ou 15,24 cm (6"") pour les pompes submersibles multi-étagées à des températures de fonctionnement comprises entre 0 °C et 90 °C.
De plus, la présente norme spécifie la méthode suivant laquelle une autorité de surveillance du marché peut vérifier la valeur de l’indice de rendement minimal (MEI) d'une gamme de pompe indiqué par le fabricant.
Même si le fabricant d’une gamme de pompe est libre de choisir la méthode lui permettant de prouver la valeur nominale de l’indice de rendement minimal (MEI), la présente norme spécifie néanmoins une méthode permettant de prouver que cette valeur nominale satisfait aux exigences dans l’intervalle de confiance avec une probabilité suffisamment élevée.

Črpalke - Minimalna zahtevana učinkovitost centrifugalnih vodnih črpalk

Ta evropski standard vključuje tesnilne vodne črpalke za črpanje čiste vode, vključno z vgrajenimi črpalkami v ostalih proizvodih. Črpalke, zasnovane in izdelane kot črpalke z nizko porabo za tlake do 16 barov pri sesalnih vodnih črpalkah in do 25 barov pri večstopenjskih črpalkah ter za temperature med –10 in 120 °C za čisto vodo pri vseh vrstah materialov.
