All HV-variant pumps are equipped with spring-loaded DN 20
valves with an opening pressure of 0.1 bar (or 0.8 bar for the
pressure side) and connection for PVC tube 19 x 27.
DDI 60-10 has a special dosing head.
Note that the HV-variant pump has other
dimensions than the standard pump and that
other connection line dimensions might be
required!
4.4 Safety functions
4.4.1 Diaphragm leakage detection (optional)

DPressure switch
Q1Working diaphragm
Q2Signal diaphragm (intermediate layer made from fabric)
Q3Protection diaphragm
In the event of a leak in the diaphragm:
• Dosing medium penetrates between the working diaphragm
and the protection diaphragm and is transferred to the
pressure switch via the signal diaphragm.
• On the next pressure stroke, pressure is applied to the
pressure switch, which is activated. The pump indicates an
TM03 6661 4506
error but continues operating.
• The electronics operates two contacts, which can be used, for
example, to trigger an alarm signal or to switch off the pump.
• In emergency mode, the pump can continue operating for a
short time.
Warning
Danger of explosion, if dosing liquid has entered
the pump housing!
If the diaphragm is possibly damaged, don’t
connect the pump to the power supply!
Proceed as described in section 10.5 Diaphragm
breakage!
After a diaphragm leakage detection, the
pressure switch has to be checked. In case the
diaphragm of the pressure switch is broken or
affected by the dosing liquid, the pressure switch
must be replaced.
4.4.2 Pressure control
The DDI 222 pump incorporates a pressure control function.
The pressure is calculated from the motor current consumption or
is measured directly in the dosing head if a pressure sensor is
present (Flow Monitor pump option). At a user-defined pressure,
the pump is switched off automatically.
English (GB)
TM03 6611 4506
To protect the pump and system against
excessive pressure build-up, install an overflow
valve in the discharge line.
This function protects the pump, but not the system. It is
recommended that the system is protected by an overflow valve.
This function can be enabled and disabled in the second function
level of the electronics.
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.
Pressure control is primarily used to protect the
pump. This function is not a substitute for the
overflow valve.
4.5 Dimensional sketches
4.4.4 Flow compensation
The flow compensation is a function to keep the dosing flow
constant with changing system pressure. Pressure changes are
detected by the pressure sensor and the motor speed is adjusted
accordingly.
To use this function, pressure control or dosing control (Flow
Monitor) has to be activated in the electronics.
When dosing media with a viscosity similar to
water, the pump needs not to be calibrated, as
the pump already responds to the possible
change of the system pressure.
When dosing media with a viscosity different
from water or after a software update, the pump
has to be calibrated.

5.1 General information on installation
Warning
Observe the specifications for the range of
applications and installation location 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!
5.2 Installation location
Warning
Danger to life due to non-tripping of the residual
current device (RCD)!
If the pump is connected to an electric
installation where a residual current device (RCD)
is used as an additional protection, this RCD
must trip when earth fault currents with DC
content (pulsating DC) and smooth DC earth fault
currents occur. This means that a RCD type B,
sensitive to universal current, must be used.
5.2.1 Space required for operation and maintenance
5.2.2 Permissible ambient influences
Permissible ambient temperature: 0 °C to +40 °C.
Permissible air humidity: max. relative humidity:
92 % (non-condensing).
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!
5.2.3 Mounting surface
The pump must be mounted on a flat surface.
5.3 Mounting
Carefully tighten the screws, otherwise the
plastic housing may be damaged.
The pump must be installed in a position where it
is easily accessible during operation and
maintenance work.
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.

• 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.
• 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. 7 Tank installation
With open outflow of the dosing medium 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 pressure-loading valve (7i)
immediately before the outlet or the injection unit.
• To protect the dosing pump against excessive pressure
build-up, install a relief valve (6i) in the discharge line.
• For degassing media:
– Flooded suction.
– Install a filter (15i) in the suction line to prevent the valves
being contaminated.
Fig. 10 Installation with relief valve and filter
• For line lengths above 1 metre a suction pulsation damper (4i)
TM03 6666 4506TM03 6667 4506TM03 6668 4506
may be required, depending on the flow rate.

5.5 Tube / pipe lines
5.5.1 General
Warning
To protect the dosing pump against excessive
pressure build-up, install a relief valve in the
discharge line.
All lines must be free from strain!
Avoid loops and buckles in the tubes!
Keep the suction line as short as possible!
The flow must run in the opposite direction to
gravity!
Observe the manufacturer's safety instructions
when handling chemicals!
The resistance of the parts that come into contact
with the media depends on the media, media
temperature and operating pressure. Ensure that
parts in contact with the media are chemically
resistant to the dosing medium under operating
conditions!
Only use the specified line types!
Maximum suction line length
• 5 m for standard pumps when dosing media with a viscosity
similar to water and using a pulsation damper.
• 1.2 m when dosing media with a higher viscosity than water.
• 1.2 m for pumps with Flow Monitor (2 m for standard
DDI 60-10) when dosing media with a viscosity similar to water
and not using a pulsation damper.
