2 Dosing head D MBS pressure switch (optional) H Drain opening
4.3.1 HV variant for liquids which are more viscous than water
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)
Pumps with diaphragm leakage signal have a special dosing head with a diaphragm set and pressure switch. The pressure switch (socket 1) is fitted and connected to the pump on delivery.
Fig. 3 Dosing head with diaphragm set and pressure switch
for diaphragm leakage detection
Pos. Components
2 Dosing head
D Pressure switch Q1 Working diaphragm Q2 Signal diaphragm (intermediate layer made from fabric) Q3 Protection 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.

MBS: Diaphragm leakage sensor (optional) DS: Pressure sensor (Flow Monitor pump option)
English (GB)
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)

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.
