8.3 Aligning the dosing head
Fig. 8:
Aligning the dosing head
When connecting the dosing lines to the dosing pump, you must observe
the direction of through-flow (see arrow). The dosing head must be
aligned vertically. The alignment can be changed in 90° intervals.
The suction valve (3) must always point downwards. Accordingly, arrow
(2) and pressure valve (1) always point upwards. This is irrespective of the
positioning of the dosing head to the drive.
8.4 Hydraulic connections
8.4.1 Connecting hose clips
Choose the hose connection according to the condition of the hose
(material, inner diameter, wall thickness) in order to ensure maximum
pressure resistance.

Perform the following working steps:
1. Cut the hose (1) to the appropriate length neatly and at an exact right
angle.
2. Place a gasket that is suitable for the dosing medium between the
connection (5) and the valve.
3. Screw the connecting piece e to the dosing pump's valve using the
(2).

4. Thread the union nut (3) and the clamping ring (4) onto the hose.
5. Plug the hose all the way in to the grommet of connection piece.
6. Push the clamping ring onto the grommet of connection piece and
screw it to the union nut.

8.4.1.2 Size 6/12
Fig. 10:
Size 6/12 hose clips only have a union nut. It clamps the hose onto the
grommet of the connection piece and at the same time fastens on the
dosing pump's valve.
Perform the following working steps:
1. Cut the hose (1) to the appropriate length neatly and at an exact right
angle.
2. Place a gasket that is suitable for the dosing medium between the
connection (4) and the valve.
3. Push the union nut (2) and the cutting ring (3) over the hose.
4. Press the end of the hose onto the grommet of connection piece. You
can do this more easily by moistening the end of the hose on the
inside or applying some lubricant to the grommet in the cone area.
You should push at least two thirds of the hose onto the grommet of
the connection piece.
5. Push the cutting ring over the hose into the cone area on the
grommet of connection piece.
6. Screw the union nut onto the valve of the dosing pump.
