gerotor pump unit.
6. Assembly
6.1.3 Attachment
The product should, to the extent possible, be protected from hu-
midity and vibration, and should be mounted so that it is easily
accessible, allowing all further installation work to be done without
difficulty.
During assembly and especially when drilling assembly holes on the
system, always pay attention to the following:
○
Check the gerotor pump unit for any shipping damages and for
completeness.
○
The IP safety class must be observed.
○
The gerotor pump unit and its ground connection must be con-
nected to the equipotential bonding of the main machine.
○
Other units must not be damaged by assembly work.
○
The product must not be installed within range of moving parts.
○
The product must be installed at a sufficiently large distance from
sources of heat or cold.
○
Maintain safety clearances and comply with statutory regulations
for assembly and accident prevention.
○
Drill the assembly holes for the gerotor pump unit as specified in
this chapter.
○
The various designs of gerotor pump unit are secured using 4
screws according to the specific installation conditions at the
location.
○
See the connection diagrams below for the measurements and
port dimensions.
○
No radial or axial active forces may occur at the gerotor
pump unit.
○
The gerotor pump unit must be installed in a stress-free position.
○
The pump may only be commissioned and operated with an oil
supply; the pump must not run dry.
WARNING
Explosion hazard
The lubricant’s ignition temperature has to be at least
50 kelvin above the maximum permissible surface
temperature.
WARNING
Explosion hazard from non-ATEX-compliant attach-
ments and monitoring equipment
Only ATEX-compliant screw unions, lines, attachments,
and monitoring equipment may be installed on the ATEX
gerotor pump units.
