8.7.6 Priming aid
Priming aids are particularly advisable:
n
in the case of dosing pumps with small volumetric displacements per
stroke or with low stroke length settings,
n
with high uction heads,
n
with highly dense dosing media,
n
at priming for the first time due to dry valves and air in the suction line
and the dosing head,
n
in dosing systems with frequent downtimes.
Further advantages resulting from priming aids:
n
preventing cavitation in the suction line,
n
gas removal,
n
optical dosing control with small amounts,
n
smoothing of the suction flow.
