Solenoid-Diaphragm Dosing Pump MAGDOS LP Operating Instructions
BA-10231-02-V03
8.7.8 Priming aid
Priming aids are particularly advisable:

in the case of dosing pumps with small volumetric displacements
per stroke or with low stroke length settings,

with high uction heads,

with highly dense dosing media,

at priming for the first time due to dry valves and air in the suction
line and the dosing head,

in dosing systems with frequent downtimes.
Further advantages resulting from priming aids:

preventing cavitation in the suction line,

gas removal,

optical dosing control with small amounts,

smoothing of the suction flow.

8.7.9 Level monitoring
Level monitoring of suction-side feeding of the dosing medium to
prevent the tank being sucked dry and to ensure that it can be topped
up again in good time.
