5.4.2 Nozzle loads
The pump can be subjected to nozzle loads in accor-
dance with ISO 5199. See also Pricebook.
Changes in the length of the piping caused by tem-
perature are to be allowed for by appropriate meas-
ures, e.g. the installation of expansion joints.
5.4.3 Suction line
The suction lines must always be laid on a rising gra-
dient towards the pump. Otherwise, gas bubbles may
form which considerably reduce the suction line cross
section. Eccentric transition elements must be in-
stalled between different pipe diameters.
Valves which disrupt the course of flow should not be
installed directly upstream of the pump.

5.4.4 Supply lines
Supply lines should vent towards the reservoir and
are therefore to be laid with a constant downward
gradient towards the pump. Should the piping inter-
nals upstream of the pump be horizontal, a low point
can, of course, be located upstream of these inter-
nals. From here the pipe is then laid with an upward
gradient to the pump so that the gas bubbles which
form here can escape through the pump.
Valves which disrupt the course of flow should not be
installed directly upstream of the pump.
5.4.5 Discharge line
Do not arrange the shut-off valve directly above the
pump but initially provide a transition section.
The discharge nozzle velocity of the medium can – if
necessary – be reduced.
5.4.6 Venting and evacuating
Venting can take place into the discharge line or up-
stream of the discharge valve.
A venting line can also be used as a bypass, drain or
flushing line.
The pump housing is fitted with a drain connection as
a standard feature. Optionally, the drain bore can be
enlarged.

5.6 Monitoring facilities
Appropriate monitoring facilities are to be
recommended, depending on the require-
ments placed on operational safety and
availability of the unit.
