5. Assembly and installation

5.1 Unpacking and control

Please check the delivery on its integrity and transport
•
damages. In case of lost or damage, we refer to our
general sales and delivery conditions;

5.2 Preparation

Before starting the assembly of the pump, all technical
•
documentations, such as the hydraulic circuit diagram
or assembly drawing must be available.
The assembly area must be clean and free of obstacles
•
Necessary and adequate tools and lifting devices
•
must be available
Only use the indicated threads and fixing holes
•
Due to the power dissipation which is radiated over
•
the surface of Hydrokraft pump, ensure sufficient air
ventilation for the heat release.
The electric and hydraulic connections of the Hydrokraft
•
pump must be connected with the connections on the
machine, according to the circuit diagram.
Particularly unfavourable conditions
•
During the transport
•
From the manufacturer to the assembly area
•
Eventually necessary intermediate storage period
•
under unfavourable conditions
Installation on the assembly area
•
may cause pollution in the pump (water, dust, etc.). Any
residues must be removed (do not use fibre cleaning
cloths!)
If the Hydrokraft pump is lacquered again, all elastic
•
materials (flexible lines, sealing), optical displays and
electronic devices must be covered
The Hydrokraft pump should be easily accessible for
•
maintenance works. This includes routine works, such
as inspection of leakage, re-adjustment of controls and
replacing of filter-elements.
Before taking the Hydrokraft pump into operation, the
•
unit must be completely filled with oil.

5.3 Filtering of hydraulic medium

An adequate filtering of the hydraulic medium is an
•
indispensible condition for a failure-free functioning and
a long life-cycle of all hydraulic components and the
entire machine/installation
Please consider the control and replacing intervals of
•
the filter
In case of a later installation of supplementary filters,
•
ensure an arrangement which makes it easy accessible
for maintenance works outside the danger zones
Standard hydraulic medium often do not have the
•
required purity level when delivered
Before proceeding to the test-run of installations
•
with actuation in open or closed control loops, the
installation and hydraulic medium must be cleaned
according to the indications of the manufacturer, in
order to attempt a steady purity level. Unless otherwise
specified, the rinsing of the assembled installation must
be carried out in accordance with ISO 23309.
5.4 Screwed fittings & flexible lines
WARNING!
Do never couple or uncouple flexible lines or pipes
under pressure or when the Hydrokraft pump is running!
There is a considerable risk of injury caused by lashing
flexible lines and/or escaping liquids!
Inaccurate connections, screwed fitting, pipes and
•
flexible lines under pressure may cause serious injuries.
Use with preference screwed fittings and tailpieces
•
with elastomeric seals
Pipes should be in steel. Metric pipes with an external
•
diameter until 50mm should correspond to ISO 10763.
When choosing the flexible lines and pipes, make sure
•
that, concerning pressure and flow, they are accurate
for the intended use.
Flexible lines should, if possible, be purchased
•
completely tailored from the manufacturer
When installing flexible lines or pipes, you must
•
consider the installation directives from the
manufacturer, e.g. minimum bending radius, lapping
torsion moments. You will find the necessary
information in the respective product catalogue from
the manufacturer.
You should proceed to a visual inspection of all flex-
•
ible lines before taking into operation. Defective
bonding, aging, mechanical defaults may cause burst of
flexible lines.
WARNING!
Defective flexible lines must be replaced immediately
Flexible lines from unknown manufacturers or
•
incomplete identification should not be used
