Adjustment of the delivery volume:
The delivery volume can be reduced to a minimum of about 25% of the rated one. For that
purpose, take the following actions:
Turn out the plug screw
7
.
Set the required delivery volume at the adjusting nipple
7
with the wrench included in
the delivery.
Clockwise turn: Reducing the delivery volume.
Anticlockwise turn: Increasing the delivery volume.
The adjusting nipple features a hexagon, against which a spring-loaded piston exerts
pressure in radial direction. In this way, the delivery volume is prevented from auto-
matically changing. At the same time, this type of locking serves as a measure for the
adjustment of the delivery volume. Six notches correspond to one turn of the adjust-
ing nipple and reduction by approximately 33% of the rated volumetric displacement.
As for precise adjustment to a defined delivery volume per stroke, a volumetric prove-
measurement has to be taken.
The pump elements are delivered adjusted to maximum volumetric displacement.
Turn in the plug screw

5. Safety notes
5.1 Basic principle
The pump unit leaves the factory in flawless condition and ensures high technical safety.
The pump unit is in conformity with the rules of technology and the applicable safety and
health regulations. Nevertheless, in case of incorrect operation or misuse, risks are threat-
ening to the:
Lives and bodies of the users or third parties
Pump unit or other operator assets
efficient use of the pump unit
5.2 Requirements on user training
Any person getting to work on the pump unit must be authorised and trained for that purpose
by the operator. They must be able to recognise and avoid potential risks. This also includes
knowledge in the accident prevention regulations, first-aid measures, and local rescue
facilities.
The unit may be inspected, maintained and repaired by technically skilled
personnel with product-specific training only.
Work on electric facilities may be performed by skilled electricians in conform-
ity with DIN VDE 1000-10 only.
For the planning and inspection of the work, professionals with product-specific training are
responsible.
