Device
6.1
An electric motor drives a rotor. Rollers are fitted to the ends of the rotors,
which press the pump hose against the inner curvature of the dosing
head. The peristaltic pump operates by the rollers driving the feed chem‐
ical through the pump hose. The feed chemical is primed by the pump
hose automatically returning to its initial position.
6.2 Capacity
The capacity that has been set regulates the pump itself.
6.3 Operating modes
Operating modes are selected via the "Operating modes" menu.

CAUTION!
Warning of feed chemical spraying around
An unsuitable feed chemical can damage the parts of
the pump that come into contact with the chemical.
– Take into account the resistance of the wetted mate‐
rials and the ProMinent Resistance List when
selecting the feed chemical - see the ProMinent
Product Catalogue or visit ProMinent.
CAUTION!
Warning of feed chemical spraying around
An unsuitable feed chemical may cause premature wear
to the pump hose.
– Observe the pump hose's resistance and "Chemical
Resistance List DFXa" available at www.promi‐
nent.com when selecting the feed chemical.
CAUTION!
Warning of feed chemical spraying around
Pumps which are not fully installed hydraulically can
eject feed chemicals from the outlet openings of the dis‐
charge valves as soon as they are connected to the
mains.
– The pump must first be hydraulically installed and
then electrically.
In the event that you have failed to do so, press the

CAUTION!
Material damage possible due to power surges
Should the pump be connected to the mains power
supply in parallel to inductive consumers (such as sole‐
noid valves, motors), inductive power surges can
damage the control when it is switched off.
– Provide the pump with its own contacts (Phase) and
supply with voltage via a contactor relay or relay.
Should this not be possible, then switch a varistor
–
(part no. 710912) or an RC gate (0.22 µF/220 Ω,
part no. 710802) in parallel.
CAUTION!
Bonding of the contacts of your switching relay
The high starting current can cause the contacts of the
on-site switching relay to bond together if the mains
voltage switches a solenoid metering pump on and off in
a process.
– Use the switching options offered by the external
socket to control the pump (functions: Pause, Auxil‐
iary frequency or Operating modes: Contact, Batch,
Analogue).
–
Use a starting current limiter if it is impossible to
avoid switching the pump on and off via a relay.
