4.3.4 DMI 208 with diaphragm leakage detection

Fig. 5 DMI 208 with diaphragm leakage detection

4.3.5 Functional principle of diaphragm leakage
detection

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

The optoelectronic sensor contains:

• infrared transmitter

• infrared receiver.

Fig. 6 Diaphragm leakage sensor

If the diaphragm leaks,

• the liquid enters the dosing head flange.

• the light refraction changes.

• the sensor emits a signal.

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

4.3.6 Dosing controller (without Plus

3

system)

The dosing controller monitors the dosing process
and emits a pulse for each suction stroke.

Fig. 7 Dosing controller

4.3.7 HV variant for liquids which are more
viscous than water

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

5.3.2 Installation tips

• For non-degassing media with a viscosity similar
to water, the pump can be mounted on the tank
(observe the permissible suction lift).

• Flooded suction preferred (not with Plus

3

system).

• For media with a tendency to sedimentation,
install the suction line with filter (15i) so that the
suction valve remains a few millimetres above the
possible level of sedimentation.

Fig. 18 Tank installation

With open outflow of the dosing med ium or low
counter pressure

A positive pressure difference of at least 1 bar must
be ensured between the counter pressure at the
injection point and the pressure of the dosing
medium at the pump suction valve.

• If this cannot be ensured, install a pressure­loading valve (7i) immediately before the outlet or
the injection unit.

Fig. 19 Installation with pressure-loading valve

• To avoid the siphon effect, install a pressure­loading valve (7i) in the discharge line and, if
necessary, a solenoid valve (14i) in the suction
line.

Fig. 20 Installation to avoid the siphon effect

• To protect the dosing pump against excessive
pressure build-up, install a relief valve (6i) in the
discharge line.

• For degassing media:

– Flooded suction (not with Plus
