backpressure (see section
If the pump is operated with a backpressure that
deviates or if dosing a medium whose viscosity
deviates, the pump must be calibrated.
Requirements
•
The hydraulics and electrics of the pump are
connected (see section
•
The pump is integrated into the dosing process
under operating conditions.
•
The dosing head and suction hose are filled with
