With
‘metering optimised’
‘metering profile’
, the discharge stroke is elon‐
gated, the suction stroke is executed as quickly as possible. This setting is
suitable, among other things, for applications that require optimum mixing
ratios and chemical mixing that is as continuous as possible.
Under
‘Metering profile’
-
‘priming optimised’
, the suction stroke is elon‐
gated as much as possible, which makes possible the precise and
problem-free metering of viscous and gaseous media. Select this setting
to minimise the NPSH value as well.

you can reduce the nominal pressure of
the pump via the pressure stages – refer to the "Functional description”
chapter.
When selecting a pressure stage, you are simultaneously selecting the
error behaviour.

Accuracy of calibration
Normally the pump does not have to be calibrated.
The pump can be calibrated if viscous feed chemicals
are used or extremely high accuracy is required.
