21. ATEX Directive
ECO / ISOCHEM / ECLIPSE IOM ADDENDUM
ATEX Directive 94/9/EC
Potentially Explosive Atmospheres
NP550110-IOM REV B
8/10/2005
Scope
This addendum is to the Installation, Operation and Maintenance Manual of the ECO, Isochem and Eclipse Gear
Pump family of pumps. It includes all the necessary additional information to be considered when installing these
pump models in a potentially explosive environments (Group II, Category 2, G & D).
Models Included in the Assessment
G , GA and GC series ECO Mechanical sealed gear pumps
GM and GMC Isochem Magnetically driven gear pumps
E Series Eclipse Magnetically driven gear pumps
Description of Equipment
The general product description for this equipment is positive displacement external gear pumps. They are
supplied as mechanically sealed and magnetically driven versions.
Intended Usage of the Equipment
ECO / Isochem / Eclipse gear pumps are intended to be used to transfer various fluids. With proper sensors or
feedback devices they can also be used to meter fluids.
Pulsafeeder has decided to construct the pumps to meet the requirements for Group II, category 2 equipment. To
meet Category 2 equipment requirements, all possible ignition sources that can occur in normal operation of the
pumps and additionally, those that can become effective as a result of malfunctions expected to occur in service
must be considered. As the pumps are not intended to meet the requirements of category I, potential ignition
sources arising from rare malfunctions can be neglected.
