ATEX Machinery Element
The ATEX Machinery Element System provides an enhanced service to engineers, OEMs and end-users. It is a comprehensive guide to assessing mechanical seals against ATEX requirements, resulting in compliance with ATEX Directive 94/9/EC.
Most mechanical seals are classified as Machinery Elements, parts of machinery which do not fall within the ATEX Directive 94/9/EC; mechanical seals can be self-assessed and certified as part of the equipment. For more information please see the ESA ATEX position statement and EC ATEX committee page
AESSEAL® provides the necessary support to engineers, OEMs and end-users to attain the required ATEX compliance level for mechanical seals.
The AESSEAL® Addendum, together with the Application Limits sheet for the seal type and a comprehensive Worksheet Booklet, provide all necessary information for the user to determine whether the seal is suitable for a particular ATEX application.
The use of materials in ATEX zoned areas is subject to stringent restrictions and requirements stipulated in BS EN 13463-1:2009. Mechanical seals containing light metal alloy parts and non-conductive ceramics or coatings must not be incorporated into rotating equipment classified as Group II, Category 2 or 3 in potentially explosive atmospheres without approval by AES Technical Department.
If required AESSEAL® Technical Dept can provide material selection advice, and will evaluate an Atex application if provided with full application information and the Atex specification for the plant area (e.g. EX II 2G IIC c T3).
If required, our technical department can evaluate an ATEX application, provided we have full application information and the ATEX specification for the plant area (e.g. EX II 2G IIC c T3).
AESSEAL® can provide:
- ATEX Certified mechanical seals for Group II Equipment, Categories 2 & 3.
- ATEX Certification for MMVI and MMVII mechanical seals for Zone 0 applications. We have a quality procedure in place to ensure compliance with the Harmonized Standards and EC Type Examination Certificate. (Assessed and Certified by SIRA Test & Certification Ltd.)
AESSEAL® may also provide ATEX Certified seals for Zone 0 Applications.
