Seal-less rotodynamic pumps - Class II - Specification (ISO 15783:2002)

1.1 This International Standard specifies the requirements for seal-less rotodynamic pumps that are driven with
permanent magnet coupling (magnet drive pumps) or with canned motor, and which are mainly used in chemical
processes, water treatment and petrochemical industries. Their use can be dictated by space, noise, environment
or safety regulations.
Seal-less pumps are pumps where an inner rotor is completely contained in a pressure vessel holding the pumped
fluid. The pressure vessel or primary containment device is sealed by static seals such as gaskets or O-rings.
1.2 Pumps will normally conform to recognized standard specifications (e.g. ISO 5199, explosion protection,
electromagnetic compatibility), except where special requirements are specified herein.
1.3 This International Standard includes design features concerned with installation, maintenance and
operational safety of the pumps, and defines those items to be agreed upon between the purchaser and
manufacturer/supplier.
1.4 Where conformity to this International Standard has been requested and calls for a specific design feature,
alternative designs may be offered providing that they satisfy the intent of this International Standard and they are
described in detail. Pumps which do not conform with all requirements of this International Standard may also be
offered providing that the deviations are fully identified and described.
Whenever documents include contradictory requirements, they should be applied in the following sequence of
priority:
a) purchase order (or inquiry, if no order placed), see annexes D and E;
b) data sheet (see annex A) or technical sheet or specification;
c) this International Standard;
d) other standards.

Wellendichtungslose Kreiselpumpen - Klasse ll - Technische Anforderungen (ISO 15783:2002)

1.1   Diese Norm legt die Anforderungen der Klasse II für wellendichtungslose Kreiselpumpen, die mit Permanentmagnetkupplung (Magnetkupplungspumpen), oder mit Spaltrohrmotor angetrieben werden, fest, die vornehmlich in der chemischen Prozesstechnik, der Wasserbehandlung und der petrochemischen Industrie eingesetzt werden. Ihre Verwendung kann durch den Raumbedarf, das Geräusch, die Umgebungsbedingungen und die Sicherheitsvorschriften bestimmt sein.
Wellendichtungslose Pumpen sind Pumpen, bei denen ein innerer Rotor vollständig in einen Druckbehälter, der das Fördergut beinhaltet, eingetaucht ist. Der Druckbehälter oder die erste Schutzhülle wird durch statische Dichtungen wie z. B. Flachdichtungen oder O-Ringe abgedichtet.
1.2   Pumpen werden in der Regel mit einer anerkannten genormten Spezifikation (z. B. ISO 5199, Explosionsschutz, Elektromagnetische Verträglichkeit) übereinstimmen, es sei denn, besondere Bestimmungen sind in dieser Norm festgelegt.
1.3   Diese Norm beinhaltet Konstruktionsmerkmale im Zusammenhang mit der Installation, der Wartung sowie der Betriebssicherheit von Pumpen und legt die Merkmale fest, die zwischen Besteller und Hersteller/Lieferer zu verein-baren sind.
1.4   Wenn die Übereinstimmung mit dieser Norm und eine bestimmte Ausführung gefordert ist, können alternative Ausführungen angeboten werden, wenn sie den Festlegungen dieser Norm genügen und die Alternativen im einzelnen beschrieben werden. Es können auch Pumpen angeboten werden, die nicht mit allen Anforderungen dieser Norm übereinstimmen, vorausgesetzt, dass die Abweichungen vollständig ausgewiesen und beschrieben werden.
Falls sich aus den Unterlagen Widersprüche hinsichtlich der technischen Anforderungen ergeben, gelten die Unterlagen in nachstehender Reihenfolge:
a) Bestellung (oder Anfrage, falls kein Auftrag erteilt worden ist) (siehe Anhänge D und E);
b) Datenblatt (siehe Anhang A), oder technisches Beiblatt oder Spezifikation;
c) Diese Norm;
d) Andere Normen.

Pompes rotodynamiques sans dispositif d'étanchéité d'arbre - Classe II - Spécifications (ISO 15783:2002)

1.1 La présente Norme internationale couvre les exigences concernant les pompes rotodynamiques sans
dispositif d'étanchéité d'arbre entraînées par un accouplement magnétique à aimant permanent (pompes à
entraînement magnétique), ou par un moteur chemisé à rotor noyé, et qui sont principalement utilisées dans les
processus chimiques, le traitement de l'eau et les industries pétrochimiques. Leur utilisation peut être dictée par
l'espace, le bruit, l'environnement ou les réglementations en matière de sécurité.
Les pompes sans dispositif d'étanchéité d'arbre sont des pompes dont le rotor est complètement isolé dans une
enceinte sous pression contenant le liquide pompé. L'enceinte sous pression, ou dispositif de confinement
primaire, est étanchée statiquement par des joints plats ou toriques.
1.2 D'une manière générale, et sauf exigences particulières spécifiées dans la présente Norme internationale,
les pompes sont censées être conformes aux spécifications des normes reconnues (par exemple ISO 5199,
protection contre les explosions, compatibilité électromagnétique).
1.3 La présente Norme internationale comporte des particularités de conception qui ont trait à l'installation, à la
maintenance et à la sécurité opérationnelle des pompes et définit les éléments qui doivent faire l'objet d'un accord
entre l'acheteur et le fabricant/fournisseur.
1.4 Lorsque la conformité à la présente Norme internationale a été demandée et que celle-ci fait appel à une
caractéristique spécifique de conception, d'autres conceptions peuvent être proposées, à condition qu'elles
répondent à l'objectif de la présente Norme internationale et qu'elles soient décrites en détail. Des pompes qui ne
sont pas conformes à toutes les exigences de la présente Norme internationale peuvent également être
proposées, à condition que les écarts soient complètement identifiés et décrits.
Lorsque des documents comprennent des exigences contradictoires, il convient de les appliquer dans l'ordre de
préséance suivant:
a) commande (ou appel d'offres, si la commande n'est pas passée), voir les annexes D et E;
b) fiche technique (voir l'annexe A) ou spécification technique;
c) la présente Norme internationale;
d) d'autres normes.
