Technical specifications for centrifugal pumps - Class III (ISO 9908:1993)

Covers class III requirements for centrifugal pumps of single stage, multistage, horizontal or vertical construction (coupled or close-coupled) with any drive and any installation for general application. Includes design features concerned with installation, maintenance and safety of such pumps including baseplate, coupling and auxiliary piping but excluding the driver, if it is not an integral part of the pump.

Technische Anforderungen für Kreiselpumpen - Klasse III (IS0 9908:1993)

Diese internationale Norm gilt für die Anforderungen der Klasse III an einstufige oder mehrstufige Kreiselpumpen in horizontaler oder vertikaler Bauart (mit Kupplung oder als Blockpumpe) mit beliebigem Antrieb und beliebigem Einbau für allgemeine Zwecke. Diese Internationale Norm schließt Ausführungsmerkmale ein, soweit sie sich auswirken auf Aufstellung, Wartung und Betriebssicherheit der Pumpe, einschließlich Grundplatte, Kupplung und Hilfsrohrleitungen, jedoch ohne Antriebsmaschine, sofern diese nicht Teil der Pumpe ist.

Spécifications techniques pour pompes centrifuges - Classe III (ISO 9908:1993)

1.1 La présente Norme internationale couvre les spécifications de la classe III des pompes centrifuges à un ou à plusieurs étages, de construction verticale ou horizontale (à accouplement normal ou serré), associées à n'importe quel type d'entraînement, dans n'importe quelle installation pour utilisation générale. 1.2 La présente Norme internationale comprend les caractéristiques de conception relatives à l'installation, l'entretien et la sécurité de ce type de pompes, y compris le socle, l'accouplement et les tuyauteries auxiliaires, mais à l'exclusion de la machine d'entraînement, si celle-ci ne fait pas partie intégrante de la pompe. 1.3 Lorsque l'application de la présente Norme internationale est demandée: a) et qu'elle spécifie une conception particulière, des conceptions différentes, répondant à l'esprit de la présente Norme internationale, peuvent être proposées, dans la mesure où la variante est décrite en détail; b) des pompes ne satisfaisant pas à toutes les exigences de la présente Norme internationale peuvent être proposées, dans la mesure où tous les écarts sont indiqués.

Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
technical committees. Each member body interested in a subject for
which a technical committee has been established has the right to be
represented on that committee. International organizations, governmental
and non-governmental, in liaison with ISO, also take part in the work. IS0
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard IS0 9908 was prepared by Technical Committee
lSO/TC 115, Pumps, Sub-Committee SC 1, Dimensions and technical
specifications of pumps.
Annexes A, B and C form an integral part of this International Standard.
Annexes D, E, F and G are for information only.

Introduction
This International Standard is the third of a set dealing with technical
specifications of centrifugal pumps; they are designated as Classes I, II
and III. Class I (see IS0 9905) comprises the most severe and Class III
(this International Standard) the least severe requirements. For require-
ments for Class II centrifugal pumps, see IS0 5199.
The selection of the class to be used is made in accordance with the
technical requirements for the application for which the pump is intended.
The class chosen is to be agreed between purchaser and
