4.3.5 Functional principle of diaphragm leakage
detection

Pumps with diaphragm leakage detection (MLS)
have a special dosing head flange for an
optoelectronic sensor. The pump is supplied with the
diaphragm leakage sensor (MLS) already installed.

The optoelectronic sensor contains:

• infrared transmitter

• infrared receiver.

Fig. 6 Diaphragm leakage sensor (MLS)

If the diaphragm leaks,

• the liquid enters the dosing head flange.

• the light refraction changes.

• the sensor emits a signal.

The electronics operates two contacts, which can be
used, for example, to trigger an alarm signal or to
switch off the pump.

4.3.6 Flow Monitor for dosing control

The pressure sensor (Flow Monitor pump option) is
used as a dosing controller and to monitor the
pressure for the whole power ranges.

The Flow Monitor for dosing control consists of a
pressure sensor integrated in the dosing head.

The pressure sensor is available as Flow Monitor
pump option. The pressure sensor is fitted to the
pump on delivery. Upgrades are not possible.

4.3.7 HV variant for liquids which are more
viscous than water

All HV-variant pumps are equipped with
spring-loaded valves, some have a larger nominal
diameter and adapters.

TM03 6216 4506

Note

Pressure control is primarily used to
protect the pump. This function is not
a substitute for the overflow valve.

Note

Note that the HV-variant pump has
other dimensions and that other
connection line dimensions might be
required!

input/display of the dosing flow in l/h or gal/h.
Quasi continuous dosing (short suction stroke,
dosing stroke as long as possible).

• contact signal control
input/display in ml/contact, most constant dosing

• current signal control 0-20 mA / 4-20 mA
Adjustment of volumetric flow proportional to the
current signal (displayed in l/h).
Weighting of current input/output.

• batch dosing
setting the dosing capacity and dosing flow per
batch triggered manually or by an external
contact signal

• batch dosing with timer functions

– setting the dosing capacity and dosing flow per

batch
– setting thestart time for first batch
– setting the repeat time for subsequent batches.

• slow mode (for viscous media)
long suction stroke.

5. Installation

5.1 General information on installation

5.2 Installation location

5.2.1 Space required for operation and
maintenance

The control elements must be easily accessible
during operation.

Maintenance work on the dosing head and the
valves must be carried out regularly.

Provide sufficient space for removing the dosing
head and the valves.

5.2.2 Permissible ambient influences

Permissible ambient temperature: 0 °C to +40 °C.
Permissible air humidity: max. relative humidity:

92 % (non-condensing).

5.2.3 Mounting surface

The pump must be mounted on a flat surface.

5.3 Mounting

5.3.1 Horizontal mounting

Fig. 10 Drilling scheme

• Use four M6 screws to mount the pump on the
tank or on a console so that the suction valve is
at the bottom and the discharge valve is at the
top (dosing always flows upwards).

5.3.2 Vertical mounting

1. Mount the pump on a vertical surface (e.g. a wall)
using four M6 screws.

2. Unscrew the dosing head (four inner dosing head
screws (1q + 2q)).

3. Turn the intermediate ring (4q) so that the
discharge hole points downwards.

4. Turn the dosing head 90 ° so that the suction
valve is at the bottom and the discharge valve is
at the top (dosing always flows upwards).

5. Cross-tighten the screws using a torque wrench.
Maximum torque:
DDI 0.4 - DDI 5.5: 2.1 Nm.
DDI 13.8 - DDI 20: 2.5 Nm.

Fig. 11 Vertical mounting

5.3.3 Diaphragm leakage detection

With diaphragm leakage detection:

• Screw the sensor from the bottom into the
opening in the dosing head flange.

Warning
Observe the specifications for the

installation location and range of
applications described in sections

1. General information and

5.2 Installation location.

Warning
Faults, incorrect operation or faults on

the pump or system can, for example,
lead to excessive or insufficient
dosing, or the permissible pressure
may be exceeded. Consequential faults
or damage must be evaluated by the
operator and appropriate precautions
must be taken to avoid them!

Caution

The DDI 0.4-10 (not with Plus3 system)
should be operated with flooded
suction!

Note

The pump must be installed in a
position where it is easily accessible
during operation and maintenance
work.

Caution

The installation site must be under
cover!
Ensure that the enclosure class of
motor and pump is not affected by the
atmospheric conditions.

Pumps with electronics are only
suitable for indoor use!
Do not install outdoors!

Caution

Carefully tighten the screws, otherwise
the plastic housing may be damaged.
