6 Dispensing with PD22
For optimal dispensing with the PD22, the following should be observed:
6.1 Vessel Placement
In order to build up adequate pressure and reduce friction, it is recommendable to place the
vessel containing fill media at the same level as pump head or preferably above the pump
head level. Placing the vessel higher than pump head level provides positive product support
and may reduce the calibration interval. It is also recommended to place the vessel as close
as possible to the pump on suction side.
