KRAL KV - 10 Operation; 10.1 Dangers during operation; 10.2 Commissioning

10 Operation
10.1 Dangers during operation
1. Ensure that the operating data on the rating plate of the motor agree with the operating data of
the pump and with the local power supply.
2. Carefully earth the pump bracket foot, base frame or pedestal via the screwing.
3. Connect the motor in accordance with the operating instructions and circuit diagram in the motor
terminal block.
4. When connecting the pump unit to the complete system continue equipotential bonding.
10 Operation
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 pipe system on the
pressure side before the first shut-off device.
o Before commissioning, make sure that the suction line and pump are filled.
o Pumped liquids can be hot, poisonous, combustible and caustic. Use corresponding protective
equipment.
o Ensure that the pump station is only operated within the operating limits.
o Wear hearing protection if you work for a longer time directly at the pump.
o Ensure that the maximum permissible system pressure is not exceeded.
o Ensure that during cooling down or heating up the pump is only subjected to slow temperature
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 impair the service life of the pump. If the pipe system is flushed using the
pump during the initial commissioning, an additional commissioning filter has to be installed temporarily
before the pump at the system.
Personnel qualification: o Fitter
Personal protective equipment: o Work clothing
o Protective gloves
o Safety boots
DANGER
Magnetic field.
Risk of death for persons with cardiac pacemaker, metallic implant or neurostimulator.
► Under no circumstances may persons with cardiac pacemakers, metallic implant or
neurostimulator perform work on the pump station.
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 installed (mesh width0.02 mm)
1. Clean the complete pipe system before commissioning in order to protect the pump.
2. Flush the pipe system at least 50 – 100hours.
