SAFETY ADVICE
2 Safety advice
These operating instructions include safety instructions.
Follow all instructions in order to prevent personal injury, damages to the
environment or damage to materials.
2.1 Basic safety advice
Basic safety advice includes instructions that ensure that the device is operated safely
or kept in a safe condition.
Not complying with the following safety advice can have the following consequences:
•personal injury, environmental or material damage;
•important functions in the device fail;
•maintenance and servicing methods prescribed are unsuccessful;
•any rights to claim indemnification are rendered null and void.
To protect yourself and the environment, please comply with the following
instructions.
If necessary, brief people about the safety advice and warnings.
Malfunctions
Operating the device if it is not operating correctly could be fatal, harm the environment
and cause material damage to the device.
If a malfunction occurs switch the device off immediately.
Hazardous media
The device material could be destroyed if you use media not intended for use to operate
the device. Physical injury, environmental damage and material damage to the device
may result.
Before operating the device with media not intended for use, check that the material
the device is made of is compatible with the media.
Protective gear
Operating or carrying out work on the device without protective gear could cause
serious injury.
When handling the device, please wear the protective clothing required.
Hot surfaces or components
The device can become hot depending on the media used, the area where the device is
fitted and the type of operation. Heat can cause serious injuries.
Depending on the wall temperature, provide heat insulation for the device when
fitting it.
Fit protective devices that prevent contact with the device.
Shut-off device
The device itself has no shut-off device. When installing the device, shut-off devices
must be installed separately.
Before commissioning the device, install a suitable shut-off device to the motive
medium pipe to the device (upstream of the motive medium inlet to the device).

SAFETY ADVICE
Excessive noise
During operation, noise emitted from the device can harm hearing and the environment.
When fitting the device, take steps to protect against noise.
During operation, wear suitable hearing protection.
Please observe statutory regulations on noise protection.
Corrosion
Stainless steel components have been pickled and passivated to protect them from
chemicals. A primer has been applied to components made of carbon steel/ductile cast
iron. This primer is not sufficient to prevent any impact from ambient conditions if the
device is operated outdoors. Operating the device outdoors without any extra corrosion
protection will lead to material damage.
When operating the device outdoors, take appropriate precautions to protect it from
corrosion.
Maintenance and servicing work
The device is only safe to operate if in perfect condition. The operator is responsible for
the device being in a proper and safe condition.
Ensure that the specified maintenance work is carried out regularly.
Carry out the specified checks before operating the device.
2.2 Proper usage
The purpose of the device is to convey media such as liquids and solids in the process
concerned. The media are conveyed under higher pressure, mixed and transferred to
the next stage in the process.
The device may only be operated within the confines specified and in line with technical
specifications. Chapter 12 Technical data
The device is only suitable for operation outdoors if appropriate protection from
corrosion has been applied.
Incorrect handling or other usage of the device is not as intended and is therefore not
allowed. The manufacturer accepts no liability for any damage that might be caused as
a result.
2.3 Danger zones
Depending on how the device is used, the liquid applied and the type of connection,
danger zones are defined as the areas where the motive medium and suction medium
enter and where the mixed flow is discharged, as well as the area of the body.
Only stay in danger zones if there is an urgent need and with due caution.
Avoid staying in danger zones unnecessarily.

SAFETY ADVICE
2.4 Safety and protective devices
Malfunctions or improper operation can lead to unacceptably high pressure building up
on the outlet side and life-threatening situations, as well as material damage. Depending
on how the device is used and which media are applied, the operator might have to fit
suitable safety and protective devices separately. The device itself has no safety and
protective devices. These are not included in the scope of supply.
Ensure that the design pressures specified in the technical data are never
exceeded. Chapter 12 Technical data
Plan and mount extra safety devices on site (e.g. safety valves, rupture discs).
Check the safety devices regularly.

Warnings precede any hazardous steps. Warnings are structured as follows:
SIGNAL WORD
The type and source of the danger
An explanation of the type and source of the danger.
Measures to be taken to prevent the danger.
2.5.2 Danger classification of warnings
Warnings are classified to indicate the severity of the danger. Danger classifications and
the associated signal words and warning symbols are explained below.
DANGER
Fatalities or serious injuries are imminent.
WARNING
Fatalities or serious injuries are possible.
CAUTION
Slight injuries are possible.

DEVICE STRUCTURE AND HOW IT FUNCTIONS
3.2 How it functions
The liquid jet ejector is a jet ejector that pumps by using a motive medium as the source
of energy. A jet ejector does not have a mechanical drive or any movable parts. The
field of application is determined by the shape of the flow area.
Liquid jet liquid ejector (example, not to scale)Fig.: 2

motive medium inlet
2
motive nozzle
3
outlet diffuser
4
flushing nozzle
5
hopper
On the liquid jet ejector, the liquid serves as the motive medium for sucking up another
medium and conveying it at a higher pressure. Between the motive nozzle and the
diffuser, the suction medium is introduced into the head through the hopper. The motive
medium is accelerated in the motive nozzle. The motive medium and the suction
medium are then mixed and compressed together to the required pressure up to the
outlet diffuser.
3.3 Equipment and accessories
In order for the device to work properly, shut-off devices are not required in the suction
pipe and mixed flow pipe. Shut-off devices (shut-off valve, gate valve or ball valve),
measuring instruments and pipes are functional components associated with the device.
These could be necessary if the operator needs them. They are not included in the
scope of supply.
