NOTICE!
Property damage due to dry running!
Ensure that the pump is correctly filled.
NOTICE!
Irreparable damage to the pump system due to throttling on the
outlet side!
–
Severe loading of the pump due to liquid sludge with throttling
on the outlet side.
–
Never operate the pump against a closed or partially closed
valve in the outlet line.
–
Never throttle the outlet side.
NOTICE!
Risk of cavitation due to throttling of the media flow!
–
Open the inlet side valve fully and do not use for regulating the
pump capacity.
–
Regularly check the filter for soiling.
–
Maintain the viscosity of the media being pumped within the
specified range (
Pump data sheet).
NOTICE!
Property damage due to incorrect alignment
As soon as the pump system has reached the operating tempera-
ture following start-up:
–
Check alignment anew!
1.
Ensure that the pumped medium is at the operating temperature (
Pump
data sheet).
2.
Fully open inlet side valve.
3.
Fully open outlet side valve.
4.
Switch on the motor and ensure that it runs smoothly.
5.
For pumps with hot conveyed medium: Ensure temperature change of less
than 2 K/min.
6.
After initial operation under pressure at operating temperature, check that
the pump is leak-tight.
7.
After reaching operating temperature, check that the alignment is correct
