Fig. 10 Set-up without foundation
1.
Lift the base plate with the aggregate
(
Transport with lifting gear, page 11).
2.
Mount the four levelling feet as illustrated.
3.
Position the aggregate on the surface.
4.
Adjust the base plate height by means of the levelling feet
as illustrated above:
Use the wrench to hold the hexagon nut at the levelling
foot (3).
Loosen the hexagon nut (1).
The height can be adjusted by turning the hexagon nut
(2).
Tighten the hexagon nut (1) (
Tightening torques,
page 42).
Use the integrated spirit level to check whether the ag-
gregate is level end to end and side to side with a
maximum allowable tilt of 1 mm/m.
Repeat this process until the base plate has been cor-
rectly aligned.
5.4 Set-up on torsion-resistant level
surface/frame
Only possible with motor feet
Auxiliary means, tools, material:
wrench
1
1 Surface/frame
Fig. 11 Set-up on level surface/frame
1. Mount the motor feet as illustrated (
Dimension drawing,
page 46 et seq.).
2.
Position the aggregate on a torsion-resistant level sur-
face/frame.
3.
Screw the aggregate to the surface/frame.
5.5 Motor
installation
Only necessary if aggregate set-up is completed at the
installation site.
CAUTION
Risk of material damage caused by knocks and bumps!
►
Do not tilt the coupling halves when slipping them on.
►
Do not knock on or hit any pump components.
1.
Apply a razor-thin layer of molybdenum disulfide
(e.g. Molykote®) on the pump and motor shaft.
2.
Insert fitting keys (if required).
3.
Without mounting rig:
Remove the rubber buffers
Heat the coupling halves to approx. 100 °C
4.
Slip on the pump and motor-side coupling halves until the
shaft end is flush with the coupling hub.
Make sure to keep the required clearance between the
coupling halves (
Fine adjustment of coupling, page
16).
5.
Tighten the grub screws on both coupling halves.
6.
Lift the motor and put it down on the base plate.
7.
Adjust the motor shaft to the height of the pump shaft using
suitable shims for the motor.
8.
Screw in and slightly tighten the motor screws.
5.6 Planning pipe system
5.6.1
Dimensioning supports and connections
CAUTION
Risk of material damage if the pipes apply excessive forces
and torques to the pump/aggregate!
►
Make sure the permissible values are complied with
(
DIN ISO 9908).
1.
Calculate the piping forces and observe all operating condi-
tions:
cold/warm
empty/filled
depressurized/pressurized
position changes
2.
Make sure the pipe supports have permanent low-friction
properties and do not seize up due to corrosion.
3.
If required, provide for pipe compensators.
5.6.2
Specifying nominal diameter
Size of suction/pressure connections
(
Operating connections, page 41)
►
Keep the flow resistance in the pipes as low as possible.
1.
Nominal suction pipe diameter
≥
nominal suction connec-
tion diameter
2.
Nominal pressure pipe diameter
≥
nominal pressure con-
nection diameter.
