Precise metering is only possible when the back pres‐
sure is maintained at ≧ 3 bar at all times.
– Use appropriate measures to ensure a back pres‐
sure of approx. 3 bar if you are metering with a free
outlet.
The maximum loads at the discharge and suction connector are as fol‐
lows:

Fx [N] ±60 ±120
Fy [N] ±60 ±120
Fz [N] ±60 ±120
Mx [Nm] ±3 ±6
My [Nm] ±3 ±6
Mz [Nm] 0 0
Before starting up, replace the sealing stopper in the dosing head with the
selected diaphragm rupture sensor.
The necessary back pressure for the reliable triggering of the diaphragm
rupture sensor is ≧ 3 bar from the process pressure. A signal is only gen‐
erated above approximately 2 bar system back pressure in the event of
diaphragm rupture.
