1 About this product
The assembly and operating instructions for the peristaltic pump
DULCO®flex DF4a are targeted at people who, at the very least,
have the qualifications of a trained person, see
Ä Chapter 3.2
‘User qualification’ on page 12 . Should higher qualifications be
necessary, then this fact is described at the start of a chapter.
The printed version of the assembly and operating instructions is
naturally not updated. We would therefore ask you to regularly visit
the manufacturer’s homepage www.prominent.com to find out
about the new electronic versions of the assembly and operating
instructions. These versions may contain, among other things,
information about new fault remedies or spare parts.
The peristaltic pump DULCO®flex DF4a is a pump designed for
metering liquids. The feed chemical is pumped by the rotor
squeezing on the hose. No valves are needed for this, which
ensures gentle handling of the feed chemical.
A2537
Fig. 1: DULCO®flex DF4a
Typical applications include processes where only a low feed pres‐
sure is required.
The metering pump features several inputs for setting the capacity.
The step motor means that the capacity can be set continuously
variably.
The key features:
nCapacity range 0.5 – 12 l/h, 4 ... 2 bar.
nPharMed® hose material.
nStep motor, speed-controlled.
nContinuously variable adjustment of the capacity either man‐
ually or externally via contacts or analogue signal 0/4 ... 20 mA
and 0 ... 10 V.
nPriming function (high-speed run).
nSpring-mounted rollers for uniform roller pressure and
increased service life of the hose.
nSelectable capacity adjustment, e.g. increase as required or
night set-back.
nCapacity appears on the display in l/h.
nReverse direction of rotation, among other things useful for
backflushing.
nHousing degree of protection IP 65.

1.2 Construction and functional description
The pump comprises three main components:
nDrive unit (step motor)
nLiquid end (rotor, rollers and pump hose)
nControl unit
The pump features a plastic housing. The plastic housing com‐
prises an upper and lower part, which are screwed together. The
lower part contains the PCBs for the motor control. The upper part
of the housing accommodates the motor and display PCB with dis‐
play and keys.
The liquid end is mounted at the front and is sealed by a screw-on
transparent cover. The pump hose can easily be replaced after the
transparent cover has been removed.
The step motor drives the rotor. Two spring-mounted rollers at the
ends of the rotor press against the pump housing. The pump hose
runs along the inner curve of the dosing head.
The rotary movement of the rotor alternately presses and releases
the rollers in relation to the pump hose. The liquid is drawn in by
suction and pumped into the pressure hose.
The pump is operated by the control unit. The required metering
level and operating mode are set on the control unit. Metering is
controlled by the control unit or by an external contact, level and/or
pause input.
