2.2 Safety notes
WARNING!
Danger from hazardous sub‐
stances!
Possible consequence: Fatal or
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.
Safety and Responsibility
10

Protective equipment
The transparent cover on the
liquid end serves to prevent
direct contact with the rotor and
escaping chemicals in the
event of a ruptured hose.
Information in the event of an emer‐
gency
In the event of an electrical accident,
disconnect the mains cable from the
mains power supply or press the
emergency cut-off switch fitted on the
side of the system. If feed chemical is
escaping, switch off the pump by
pressing [Stop/Start] . If necessary
ensure that the hydraulic system
around the pump is at atmospheric
pressure. Adhere to the safety data
sheet for the feed chemical.
2.3 Intended use
nOnly use the unit to meter liquid
media.
nOnly use the unit in accordance
with the technical data and speci‐
fications outlined in the operating
instructions.
nAny other uses or modifications to

Functional description
An electric motor drives a rotor.
Spring-mounted rollers are fitted to
the ends of the rotors, which press
the pump hose against the inner wall
of the dosing head.
The peristaltic pump operates by the
rollers driving the feed chemical
through the pump hose. The feed
chemical is primed by the pump hose
returning to its initial position.

that can form sediment, ensure
that the foot valve is suspended
a minimum of 50 mm above the
base of the tank.
8. Guide a hose line into the
storage tank from the leakage
fitting.
5.3 Electrical installation of the
peristaltic pump
– Only carry out the electrical
installation once the
mechanical and hydraulic
installations have been
completed.
– During installation, ensure
that the mains cable is de-
energised and has been
secured to prevent it from
being switched on again.
– Fit a short-circuit fuse
during installation.
– Fit an Off switch for the
mains power supply during
installation.
