Motor-driven diaphragm dosing pump
MEMDOS LB
Operating instructions
2.2 Warnings for use within explosive-risk zones
ATEX certified versions of the MEMDOS LB dosing pump can be used in
potentially explosive atmospheres. The following warnings only apply for
use in such areas:
DANGER
Danger to life through explosions!
Explosions may result which could result in fatal injuries.
ð
Use only ATEX certified versions of the MEMDOS LB dosing pump in
potentially explosive atmosphere (check the information on the rat-
ing plate).
DANGER
Danger to life from electrostatic charge!
Static electricity in explosive risk areas can build up when dosing flam-
mable liquids. Explosions may result which could result in fatal injuries.
ð
Earth the dosing pump, drive motor and all metal parts along the
suction and pressure piping route.
ð
Only use dosing heads made of stainless steel. In exceptional cases,
carbon-filled PTFE dosing heads are also possible. For this, contact
Lutz-Jesco GmbH.
DANGER
Danger to life from the incorrect spare parts!
Original Lutz-Jesco GmbH diaphragms from 90 mm in diameter are
fitted with special conductive diaphragms to prevent static charging. If
unsuitable membranes from other manufacturers are fitted, this can
lead to electrostatic charging in explosive risk areas. Explosions may
result which could result in fatal injuries.
ð
Only use original diaphragms for spare parts. This applies to MEM-
DOS LB 80 – 1010 dosing pumps.
