10.6 Explosion protection
regulations
► For the use of equipment in hazardous areas
within the EU following regulations have to be
observed.
- DIRECTIVE 1999/92/EC on minimum
requirements for improving the safety and
health protection of workers potentially at risk
from explosive atmospheres
- EN 1127-1: Explosive atmospheres - explosion
preventation and protection - part 1: basic
concepts and methodology
- EN 13463-1: Non-electrical equipment for
potentially explosive atmospheres - part 1:
Basic method and requirements
- EN 13463-5: Non-electrical equipment for
potentially explosive atmospheres - part 5:
Protection by constructional safety
- Regulation (EC) 1272/2008 (CLP)
► National rules and regulations have to be
observed.
10.7 Classification of zones for
explosion hazard areas
Explosion hazard areas are defined as areas in which
explosive atmospheres may occur in potentially
dangerous volumes on account of local and operational
conditions.
Areas in which explosions may occur on account
of flammable gases, vapours or mists, following
classification of zones is applied:
• Zone 0: Dangerous explosive atmosphere persists
constantly or for a long time.
• Zone 1: Dangerous explosive atmosphere persists
occasionally.
• Zone 2: Dangerous explosive atmosphere persists
rarely and briefly.
Explanation of the zone classification when
using drum pumps for flammable liquids
• Inside the drum or container. Zone 0
• Bunghole of the drum or the upper edge of the
container: Boundary between zone 0 and zone 1
• Rooms in which media are transferred from one
drum or container to another: Zone 1
For drum and container pumps this means that:
► Only pump tubes of unit group II, category 1/2 G
may be used to pump flammable liquids.
► Regardless of their type of protection, motors
may not be used in zone 0.
► Motors of unit group II, category 2 G may be used
in zone 1.

10.8 Traceability

Products for potentially explosive atmospheres are
identified by an individual serial number.
Lutz Pumpen ensures the traceability of this device
up to the initial point of delivery according to ATEX
Directive.
All persons who redeliver the device are obliged to
guarantee its traceability to enable subsequent recall
actions.
