Seal-less rotodynamic pumps - Class II - Specification (ISO 15783:2026)

Edition date: 2026-05-20
In Force
Available languages: English, French
Summary: This document 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. Pumps normally conform to recognized standard specifications (e.g. ISO 5199, explosion protection, electromagnetic compatibility), except where special requirements are specified herein. This document 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. Where conformity to this document has been requested and calls for a specific design feature, alternative designs can be offered providing that they satisfy the intent of this document and they are described in detail. Pumps which do not conform with all requirements of this document can also be offered providing that the deviations are fully identified and described. Whenever documents include contradictory requirements, they are applied in the following sequence of priority: purchase order (or inquiry, if no order placed), see Annexes C and D; data sheet (see Annex A) or technical sheet or specification; this document; other standards.

Le présent document couvre les exigences concernant les pompes rotodynamiques sans dispositif d'étanchéité d'arbre entrainées par un accouplement magnétique à aimant permanent (pompes à entraînement magnétique), ou par un moteur chemise 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 règlementations 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. D'une manière générale, et sauf exigences particulières spécifiées dans le présent document, les pompes sont conformes aux spécifications des normes reconnues (par exemple l'ISO 5199, protection contre les explosions, compatibilité électromagnétique). Le présent document 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. Lorsque la conformité au présent document 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 du présent document et qu'elles soient décrites en détail. Des pompes qui ne sont pas conformes à toutes les exigences au présent document peuvent également être proposées, à condition que les écarts soient complètement identifiés et décrits. Lorsque des documents comprennent des exigences contradictoires, ils sont appliqués dans l'ordre de préséance suivant: commande (ou appel d'offres, si la commande n'est pas passée), voir les Annexes C et D; fiche technique (voir l'Annexe A) ou spécification technique; le présent document; d'autres normes.

Dieses Dokument legt die Anforderungen 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. 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 diesem Dokument festgelegt. Dieses Dokument 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 vereinbaren sind. Wenn die Übereinstimmung mit diesem Dokument und eine bestimmte Ausführung gefordert ist, können alternative Ausführungen angeboten werden, wenn sie den Festlegungen dieses Dokuments genügen und die Alternativen im Einzelnen beschrieben werden. Es können auch Pumpen angeboten werden, die nicht mit allen Anforderungen dieses Dokuments 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 Anhang C und Anhang D; b) Datenblatt (siehe Anhang A), oder technisches Beiblatt oder Spezifikation; c) dieses Dokument; d) andere Normen.
