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 Bredel are suitable for use in hazardous environments; ATEX compliant
pumps from the 700 series are listed below, in Section 2 “Pump models”.
All of Watson-Marlow’s ATEX pumps have been rated as Group II, Category
2G IIB c T4 equipment. The 701RA pumps are intended for use in gas based envi-
ronments only. The pumpheads are sold individually (for use with customer speci-
fied ATEX drives) and in defined configurations complete with Watson-Marlow ATEX
drives.
This document provides specific ATEX information and should be used in
conjunction with the original user manual.
