Operation of the pump
Filling
During pump operation, fill with the pumped liquid:
•
The suction system
•
The pressure pipe
•
The pump itself.
Also carefully fill:
•
All the sealing chambers
•
The auxiliary systems of the shaft seal
•
Heating system
•
Cooling system
Ensure appropriate monitoring measures, in case the user is unable to guarantee this.
Operation
1.
Start up the pump with the suction side fully open and and the discharge side valve fully
open: start-up with closed non-return valve is however also possible.
2.
Immediately after the start-up, adjust the discharge side valve to the operating point (Section
3.
Before the pump start-up, activate the barrier, flush and cooling systems.
Note: only when the pump is stopped, is shutdown possible, depending on the nature of the
operation.
