Explosion hazard!

The eccentric worm-drive pumps must be arranged in a way to
avoid friction and impact sparks and to allow safe operation.

Repair on explosion-proof pumps and motors may only be carried
out by the manufacturer or an authorized repair shop.

When pumping non-conductive liquids, there is a risk of the
circulated liquid becoming electrostatically charged.
Make sure to prevent any ignition hazards.

The ex-protected motor, gear and coupling must be located outside
the mobile container.

The hose used must be sufficiently conductive (see TRbF 50 annex
B).

Observe the Technical Guidelines for "Flammable Liquids" (TRbF)
and the explosion protection guidelines of the Employer's Liability In-
surance Association of the Chemical Industry (BG Chemie) during
installation and operation.

Regularly check the motors according to the relevant national safety
regulations and/or rules for prevention of accidents. (In the Federal
Republic of Germany these are for example DGUV Vorschrift 3).
Fire hazard!

For transferring liquids of explosion groups IIA and IIB and
temperature class T1 to T4, only pumps which are certified for
use in category 1 (ZONE 0) must be used.
2.6 Residual risks
Safeguards may become ineffective if the devices are not used according to the chemical
resistance chart.
Further residual risks that are linked with the repair or maintenance of the eccentric worm-
drive pump cannot be reduced constructive or by taken further precautions. If necessary,
they are mentioned at the appropriate passage.
Information
Always observe the chemical resistance chart when selecting motor,
pump, hand nozzles and hoses.
