8.4.1
Conservation
If the micro annular gear pump operates at irregular intervals or for other
reasons should be put out of operation for a longer period, it should, after
service and flushing procedure (see chapter 8.3), be filled in with a suitable
conservation liquid.
The conservation liquid may be selected from the table 11 depending on the
duration of the standstill and the resistance of the pump to the manipulated
liquid. The indicated conservation liquids are simple recommendations
and
should therefore be checked by the user as to their compatibility and suitability
.
The figure 15 presents a diagram of conservation agent selection.
Remark
: This diagram is repeated as a part of the figure 14 (shutdown
procedure of the micro annular gear pump).
After the cleansing procedure the pump should be filled with a suitable
conservation agent. You will find a choice of possible conservation agents in
the table 11.
