9.2.2Assembly of the Pump
Before assembling the pump, all parts of the
pump must be cleaned.
Installing the Hydraulic Set
Slide the hydraulic set including the shaft back
on after replacing the seal. It is vital to slide the
shaft into the pump housing until stop is
reached. Then install the pump bottom and
insert the tie rods. Tighten them cross-wise to
the torque indicated in table 2.
Adjusting the Running Gap
Correct adjustment of the running
gap is important, since the pump will
otherwise be damaged.
To adjust the running gap put the pump down
on its side. The locking screw (1) for adjustment
of the running gap is accessible from the motor
end of the pump at the center of the gear
coupling.
First push the as yet loose shaft toward the
pump housing until stop is reached. Then check
with your fingers whether the edge of the
lowest impeller is on the same height with the
edge of the bottom chamber opening. If
necessary, correct the shaft position by turning
the locking screw and pushing the shaft
forward at the same time.
The running gap has been adjusted correctly
when no difference can be sensed anymore
between the edge of the lowest impeller and
the edge of the bottom chamber opening.
Tightening the Adapter Sleeve
Once the running gap has been adjusted
correctly, the shaft can now be fastened with
the adapter sleeve. To do so, put the pump
down on its side and turn the pump shaft at the
pump coupling half until the wrench application
surface (4) at the shaft adapter (5) is accessible
from the outside. Through an opening in the
pump housing (Fig.5) you can now block the
gear coupling by pushing a suitable tool (e.g.
screwdriver or similar) at an angle between the
teeth of the gear coupling.
