1 Introduction
Directive 94/9/EC, commonly known as the ATEX directive, carries obligations to
the person who places equipment on the market, in the EU territory, for use in
potentially explosive environments. A number of pumps manufactured by Watson-
Marlow are suitable for use in hazardous environments; ATEX compliant pumps from
the 505LA series are listed below, in Section 2 Pump models.
Watson-Marlow’s 500 series ATEX pumps have been rated as Group II, Category
2G IIB c T4 equipment for use in gas based environments only. The pumpheads
are sold individually (for use with customer specified ATEX drives) and in defined
configurations complete with ATEX drives.
This document provides specific ATEX information and should be used in
conjunction with the original 505L user manual (m-505l-gb-01).
