10 Operation
9.5 Connecting the pump unit to the power supply
1.
Check the radial displacement
ΔKr
of the coupling using a hairline gauge and feeler gauge.
Check several points along the periphery of the coupling.
2.
Check the angular displacement
ΔKw
of the coupling using a hairline gauge.
3.
Check the axial displacement
ΔKa
of the coupling using a slide gauge or feeler gauge.
4.
If the limit values of the above table are exceeded, loosen the fastening of the pump or motor and
move pump or motor in order to reduce the respective offset.

DANGER
Risk of death resulting from electric shock.
► Ensure that the electrical power supply is de-energized and is secured against being switched
back on.
► Before commissioning ensure correct grounding and equipotential bonding.
► Observe the operating instructions of the electrical components.
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.
