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 800 series are listed in Section 2 Pump models.
Watson-Marlow’s 800 series ATEX pumps have been rated as Group II, Category 2
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 Watson-Marlow ATEX drives.
This document provides specific ATEX information and must be used in
conjunction with the original 825/840 user manual (800-gb-01.pdf).
