CAUTION
All components must be level during system operation unless special provisions for bearing lubrication
and oil sealing have been made. After attaching the unit to the foundation and connecting the piping,
the pump and drive train must be thoroughly checked and, if necessary, realigned.
Improper alignment of the unit can cause damage to both the coupling and the unit itself.
Proper alignment must be taken into consideration when using an overhead
motor mount accessory. Motor feet must be firmly supported at each mounting
bolt location before the bolts are tightened. Shims should be used to fill any
gaps and ensure solid mounting and vibration prevention.
For optimum performance, the pump should be mounted directly to the
baseplate without shims. The rest of the drive train is then aligned to the pump.
For this reason, GIW baseplate designs generally allow space for shimming
under the gear reducer and motor, but not under the pump itself. The only
exception occurs in cases where regular removal and replacement of the entire
pump is stipulated during the equipment design stage. In these cases, special
instructions for alignment and shimming of the pump may be given on the pump
assembly and/or general arrangement drawings.
Checks and realignment must be done even if pump and motor are supplied
completely assembled and aligned on a common base plate. The correct
distance between the coupling halves and pulleys as specified in the
installation plan must be observed.
For V-belt installations, the pulleys are correctly aligned if a straightedge placed
vertically shows a deviation of no more than 1.0 mm (0.04 inch). Both pulleys
must be parallel.

Place of Installation
WARNING
The volute casing and shaft seal take on roughly the same temperature as the medium handled.
The shaft seal seal, bearing assembly and bearing housing must not be insulated.
Take the necessary precautions to avoid burns to personnel and adjacent equipment.
5.4
Connecting the Piping
WARNING
Danger of life when toxic or hot media are handled.
CAUTION
Never use the pump itself as an anchorage point for the piping.
Permissible forces and moments must not be exceeded (see to section 4.7).
Refer to your drawing for spool piece recommendation to ease maintenance.
Thermal expansions of the pipelines must be compensated by appropriate measures so as not to impose any extra
loads on the pump exceeding the permissible pipeline forces and moments.
An excessive, impermissible increase in the pipeline forces may cause leaks on the pump where the medium handled
can escape into the atmosphere.
The flange covers on the pump suction and discharge nozzles must be removed prior to installation in the piping.
5.4.1
Auxiliary Connections
CAUTION
These connections are required for proper functioning of the pump and are therefore of vital importance!
The dimensions and locations of the auxiliary connections (cooling, heating, sealing liquid, flushing liquid, etc.)
are indicated on the installation plan or piping layout.
