7.4.1
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 7.3), be filled in with a suitable
conservation liquid.
The conservation liquid may be selected from the table 35 depending on the
duration of the standstill and the resistance of the pump to the manipulated
liquid (table 34). The indicated conservation liquids are simple
recommendations and should therefore be checked by the user as to their
compatibility and suitability. The figure 33 presents the diagram of conservation
liquid selection.
Remark
: This diagram is repeated as a part of the figure 32 »Shutdown
procedure«.
After the cleansing procedure the pump should be filled with a suitable
conservation agent. You will find a choice of possible conservation liquids in
the table 35.
