Overview

EN ISO 15783:2003/A1:2008 - Seal-less rotodynamic pumps (Class II) - Amendment 1 is a CEN-adopted amendment to the ISO 15783:2003 specification. The standard specifies requirements for seal-less rotodynamic pumps of Class II that are driven either by permanent magnet couplings or by canned motors. These pump types are primarily intended for use in the chemical process, water treatment, and petrochemical industries where shaft-sealing systems are undesirable or pose contamination/leakage risks.

Key topics and technical requirements

• Scope and application: Defines the intended pump types (seal-less rotodynamic pumps) and the driving arrangements covered (permanent magnet coupling, canned motor).
• Class II specification: Establishes the classification and general specification framework for Class II seal-less pumps (as opposed to other classes in the parent standard).
• Materials list update (Annex F): Amendment 1 replaces Table F.1 - the comprehensive table of internationally and nationally accepted materials for pump parts. This table maps ISO/ASTM/UNS designations to EN and JIS equivalents and helps ensure material compatibility for corrosion, pressure, and mechanical performance.
• Standards development context: Prepared by ISO/TC 115 (Pumps) in collaboration with CEN/TC 197, the amendment was circulated as a draft for parallel enquiry and endorsement by CEN members.

Note: The amendment is primarily focused on material specifications and tabulated equivalencies (Annex F). It does not itself redefine pump dimensions or hydraulic performance values beyond the original ISO 15783:2003 specification.

Applications and users

This standard and its amendment are directly relevant to:

• Pump manufacturers designing and certifying seal-less rotodynamic pumps (permanent magnet coupling or canned motor designs).
• Process engineers and plant designers specifying pumps for chemical processing, petrochemical units, and water/wastewater treatment where leakage prevention and containment are critical.
• Procurement and quality teams who require standardized material equivalencies to ensure component interchangeability and compliance.
• Regulatory and compliance officers verifying that installed equipment meets recognized European/ISO material and construction practices.

Related information

• Produced under the joint ISO/CEN process (ISO/TC 115 and CEN/TC 197).
• Amendment 1 specifically updates Annex F (Table F.1) to align internationally and nationally accepted materials for pump parts.

Keywords: EN ISO 15783:2003/A1:2008, seal-less rotodynamic pumps, Class II pumps, permanent magnet coupling, canned motor pumps, materials for pump parts, chemical process industry, water treatment, petrochemical.

ISO/CEN PARALLEL ENQUIRY
The CEN Secretary-General has advised the ISO Secretary-General that this ISO/DIS covers a subject
of interest to European standardization. In accordance with the ISO-lead mode of collaboration as
defined in the Vienna Agreement, consultation on this ISO/DIS has the same effect for CEN
members as would a CEN enquiry on a draft European Standard. Should this draft be accepted, a
final draft, established on the basis of comments received, will be submitted to a parallel two-month FDIS
vote in ISO and formal vote in CEN.
To expedite distribution, this document is circulated as received from the committee secretariat.
ISO Central Secretariat work of editing and text composition will be undertaken at publication
stage.
Pour accélérer la distribution, le présent document est distribué tel qu'il est parvenu du
secrétariat du comité. Le travail de rédaction et de composition de texte sera effectué au
Secrétariat central de l'ISO au stade de publication.
THIS DOCUMENT IS A DRAFT CIRCULATED FOR COMMENT AND APPROVAL. IT IS THEREFORE SUBJECT TO CHANGE AND MAY NOT BE
