ƒ
The pipes and pump must be free of mechanical stress when installed.
ƒ
The pipes must be fixed in such a way that the pump does not have to support the
weight of the pipes.
ƒ
Clean, flush and purge the unit before connecting the pipes.
ƒ
Remove the covers from the suction and discharge ports.
ƒ
If required, install a dirt filter upstream of the pump in the pipe on the suction side.
ƒ
Then connect the pipes to the pump connecting pieces.
For further examples of installation layouts and for proper as well as inappropriate
installations, see Appendix!
6.7 Aligning the unit
小心
Incorrect alignment can result in property damage!
The transport and installation of the pump can affect the alignment. The motor must
be aligned to the pump (not vice versa).
• Check the alignment before the first start.
小心
Changes to the alignment during operation can result in property
damage.
The pump and motor are usually aligned at ambient temperature. Thermal expansion
at operating temperature can change the alignment, particularly in the case of very
hot fluids.
Adjustment may be required if the pump is required to pump very hot fluids:
• Allow the pump to run at the actual operating temperature.
• Switch off the pump then immediately check the alignment.
Precondition for reliable, smooth and efficient operation of a pump unit is proper
alignment of the pump and the drive shaft.
Misalignments can be the cause of:
ƒ
excessive noise development during pump operation
ƒ
vibrations
ƒ
premature wear
ƒ
excessive coupling wear
