very serious injuries.
Please ensure when handling
hazardous substances that you
have read the latest safety data
sheets provided by the manu‐
facture of the hazardous sub‐
stance. The actions required
are described in the safety data
sheet. Check the safety data
sheet regularly and replace, if
necessary, as the hazard
potential of a substance can be
re-evaluated at any time based
on new findings.
The system operator is respon‐
sible for ensuring that these
safety data sheets are available
and that they are kept up to
date, as well as for producing
an associated hazard assess‐
ment for the workstations
affected.

WARNING!
Danger of electric shock
Mains voltage may be present
inside the pump housing.
Immediately disconnect the
pump from the mains power
supply if the pump housing has
been damaged. Only return the
pump to service after an
authorised repair.
CAUTION!
Warning of feed chemical
spraying around
The metering pump can gen‐
erate a multiple of its rated
pressure. Hydraulic parts may
burst if a discharge line is
blocked. -
Correctly install a relief valve in
the discharge line downstream
of the metering pump.
CAUTION!
Warning of backflow
Metering pumps are not abso‐
lutely leak-tight shut-off
devices.
Use a shut-off valve, a solenoid
valve or a vacuum breaker for
this purpose.
CAUTION!
Personnel injury and material
damage
The pump can start to pump,
as soon as it is connected to
mains voltage.
Install an emergency cut-off
switch in the pump power
supply line or integrate the
pump in the emergency cut-off
management of the system.
CAUTION!
Device starts immediately
The unit does not have an
On/Of switch and begins to
work as soon as it is connected
to the mains voltage.
Only connect the device to the
mains voltage when all installa‐
tion work has been completed
and the pumped chemicals can
no longer escape in an uncon‐
trolled manner.
CAUTION!
Contact with chemicals
De-pressurise, drain and rinse
the hydraulic part of the unit
before working on it.
