Mechanical seals - Principal dimensions, designation and material codes

This standard establishes a comprehensive framework for defining the fundamental dimensions, identification markings, and material coding systems for mechanical seals. It specifies the geometric parameters and tolerances necessary to ensure interchangeability and compatibility among components manufactured by different suppliers. The document outlines standardized methods for marking seals to facilitate easy identification during inspection, maintenance, and replacement processes. Additionally, it provides a systematic approach to classifying materials based on their suitability for various operating conditions, including resistance to corrosion, temperature, and pressure. The guidelines presented within this text support consistent manufacturing practices and quality assurance across the industry. By adhering to these defined specifications, manufacturers and users can achieve improved reliability and performance in sealing applications involving rotating shafts. The approach detailed herein aims to harmonize technical requirements, thereby reducing errors in selection and installation while promoting safety and operational efficiency in fluid handling systems.
