10.1 Dangers during operation
The following safety instructions must be observed strictly:
o
Have all work carried out only by authorized qualified personnel.
o
Before commissioning ensure that a safety valve has been installed in the pressure-side pipe sys-
tem to protect the pump station.
o
Before commissioning, make sure that the suction line and pump station are filled.
o
Pumped liquids can be hot, poisonous, combustible and caustic. Use corresponding protective
equipment.
o
Observe the operating instructions of the pump and the further components.
o
Ensure that the pump station is only operated within the operating limits.
o
Ensure that during cooling down or heating up the pump station is only subjected to slow temper-
ature changes.
o
Ensure that existing safety equipment is not bypassed or activated during operation.
o
Before decommissioning ensure that the electrical power supply is deenergized and is secured
against being switched back on.
10.2 Commissioning
10.2.1
Cleaning the pipe system
Notice
Soiling in the pipe system impairs the service life of the pump station. If the pipe system is flushed us-
ing the pump station during the initial commissioning, an additional commissioning filter has to be in-
stalled temporarily before the pump station. Alternatively the strainers supplied as standard can be re-
placed during commissioning by fine-meshed commissioning strainers.
Personnel qualification:
o
Fitter
Personal protective equipment:
o
Work clothing
o
Protective gloves
o
Protective helmet
o
Safety boots
ATTENTION
Damage to equipment through additional pressure loss in the commissioning filter/commis-
sioning strainer.
► Calculate the flow resistance and determine the remaining pump intake.
► Monitor the suction-side pressure.
► Check the commissioning filter/commissioning strainer regularly.
Requirement:
ü
If required, commissioning filter/commissioning strainer installed (mesh width 0.02 mm)
1.
Clean the complete pipe system before commissioning in order to protect the pump station.
2.
Flush the pipe system at least 50 – 100 hours.
