3.2 Description
3.2.1 Features
• The fitting is intended for the following applications:
– Mixing, dosing and conveying liquid and solids-free
media
– Evacuating air from pipes and immersion tanks
– Pumping out immersion tanks and pits
• The direction of flow and the installation position must
match the directional arrow on the fitting
• The flow rate is adjustable by means of the pressure of the
propellant and the bore in the nozzle
• Connection variants available
– The screw connections are to DIN 8063 and the inserts
are to DIN/ISO
– The flange is to DIN EN 1092 (DIN 2501)
3.2.2 Function

Fig. 2 Function
The propellant medium (1) flows in the main direction of flow
through the nozzle installed in the water-jet pump. The cross-
sectional constriction caused by the nozzle bore (4) results in
an acceleration of the propellant medium, thus creating a vac-
uum in the area of the suction port (2), which sucks in any
pumped media (liquid or gaseous) present. The media leave
the water-jet pump together at discharge nozzle (3).
The suction quantity depends on the pressure of the propellant
medium and the size of the nozzle bore.

Transport, Storage and Disposal
4 Transport, Storage and
Disposal
4.1 Unpacking and inspection on delivery
1. Unpack the fitting when received and inspect it for trans-
portation damage.
2. Report any transportation damage to the manufacturer
immediately.
3. Ensure that the information on the name plate agrees with
the order/design data.
4. For immediate installation, damage packaging material
according to local regulations.
– For later installation, leave the fitting in the original
packaging.
4.2 Transportation
DANGER
Death or limbs crushed as a result transported items
falling over or tilting.
Do not stand under suspended loads.
Use lifting gear appropriate for the total weight to be trans-
ported. Weight specification (→data sheet).
Attach lifting gear in accordance with the following diagram.
Fig. 4 Attach lifting gear (example)
Lift the fitting with properly installed lifting gear and position
it at the place of installation.
4.3 Storage
NOTE
Material damage due to inappropriate storage!
Store the fitting properly.
1. Make sure the storage room meets the following condi-
tions:
–Dry

– Vibration-free
– Not in direct sunlight
– Storage temperature +10 °C to +60 °C
2. As far as possible, store the valve in its original packaging.
4.4 Disposal
Plastic parts can be contaminated by poisonous or radioac-
tive media to such an extent that cleaning will not be suffi-
cient.
WARNING
Risk of poisoning and environmental damage from
medium!
Use personal protective equipment when carrying out any
work on the fitting.
Before disposing of the fitting:
– Collect escaping medium and dispose separately
according to local regulations.
– Neutralize residues of medium in the fitting.

Installation and connection
5 Installation and connection
5.1 Preparations for installation
1. Ensure the design of the fitting is consistent with the pur-
pose intended:
– Materials used (→Type plate).
–Medium(→Order and design data).
2. Ensure the required operating conditions are met:
– Resistance of body and seal material to the medium
(→resistance lists).
– Media temperature (→Data sheet).
– Operating pressure (→Data sheet).
3. Consult with the manufacturer regarding any other use of
the device.
5.2 Planning pipelines
When mixing or dosing, suitable throttle valves, flow meters
or diaphragm seals in the pipeline are recommended.
WARNING
Risk of poisoning and environmental damage from
medium!
Leaks due to impermissible pipework forces.
Ensure that the fitting is not subject to any pulling or thrust-
ing forces or bending moments.
1. Plan pipes safely:
– No tensile or compressive forces
– No bending moments
– Adjust for changes in length due to temperature
changes (compensators, expansion shanks)
– Direction of flow according to the direction of the arrow
on the fitting
– Calming section min. 5 x DN before and after the valve
2. Dimensions (→Data sheet).
5.3 Design the layout of the fitting
For reference when designing the layout of the valve for
the specific application, guide values/characteristic curves
are described in the data sheet (→Data sheet). The char-
acteristic curves represent the relationships for propellant
medium and suction medium water at a suction height of
100 cm.
With other media (density/viscosity) the ratio may change.
STÜBBE recommends adapting the nozzle bore to the
desired operating point.
If no nozzle bore diameter is specified when ordering, a 1
mm bore will be delivered.
1. Check the characteristic curves and determine the required
diameter for the nozzle bore (→data sheet).
2. Remove the nozzle (→7.2.2 Disassemble and reassem-
ble the nozzle, Page 9 ).
3. Drill a hole in the nozzle tip with the required diameter.
4. Fit the nozzle.
5.4 Install the fitting
WARNING
Risk of poisoning and environmental damage from
medium!
Leak due to faulty installation.
Installation work on the pipes should only be performed
by technicians who have been specially trained for the
pipework in question.
NOTE
Material damage due to contamination of the fitting!
Make sure no contamination reaches the fitting.
Flush the pipe with a neutral medium.
The fitting is installed according to the connection type of
the pipes.
5.4.1 Connection with flange
1. Prepare pipe ends according to connection type.
2. Radially position the fitting and flat seal between the flange
ends.
3. Screw fitting (flange screws, nuts and
washers).
– Observe tightening torques (→9.3 Flange installation,
Page 11).
302 535 BA-2023.09.27 EN SP 820 7

Operation
5.4.2 Connection with sockets, nozzles or
female threads
1. Prepare pipe ends according to connection type.
2. Loosen the union nuts on the inserts and push same over
the pipeline end.
3. Connect inserts with pipe ends.
4. Radially push the valve between the pipeline ends and
tighten by hand using the union nuts.
5.5 Performing the hydrostatic test
Pressure test using neutral medium, e.g. water.
1. Pressurize the fitting. ensuring:
– Test pressure < permissible system pressure
– Test pressure < 1.5 PN
– Test pressure < PN + 5 bar
2. Check the fitting for leaks.
6Operation
6.1 Commissioning
Fitting correctly installed and connected
WARNING
Risk of injury and poisoning due to medium spraying out!
Use personal protective equipment when carrying out any
work on the fitting.
1. Open the supply for the propellant medium and the pumped
medium.
2. Check the desired suction quantity of the pumped medium.
If necessary, rearrange layout of the fitting (→5.3 Design
the layout of the fitting, Page 7 ).
3. After the initial stresses due to pressure and operating tem-
perature, check if the fitting is sealed.
