6.2 Torques
All nuts and screws used for the installation must be made of
stainless steel.
Use grease (Alu-paste) together with a spring washer or lock nut;
otherwise, use Loctite or a similar product for lubrication and
locking.
All stainless-steel nuts and screws should be tightened to the
following torques:
When mounting the hub/impeller, use lock washer (pos. 1107),
and tighten the two shaft nuts (pos. 1106) to a torque of 50 Nm.
See fig. 6.

6.3 Installation instructions
See section
and fig. 5.
1. Weld the connection flange to the cast-in pipe end in the tank.
2. Weld the profile section to the connection flange and pipe end.
Place it in position 12 o'clock.

3. SRP.xx.80.xx: Weld the guide claws to the connection flange.
See fig. 8.

4. Drill the holes for the mounting screws for the top fixation
bracket in the concrete.
5. Mount the screws and fit the top fixation bracket.
6. Depending on the length of the column profile, weld the
turnable part of an intermediate fixation bracket to the column
profile.

Top fixation
7. Position and align the column profile with the profile section on
the connection flange. Shorten the column profile (pos. 2) to
the correct length to match the position of epoxy insulator
(pos. C) at the top fixation bracket. A gap of 5 to 10 mm
between collar of epoxy and column profile is optimal.
See fig. 9.
8. Remove the epoxy insulator and the turnable metal part by
removing the centre screw (pos. A) and the two fixation
screws (pos. B).
9. Adapt the outside of the square epoxy insulator to the inside of
the column profile. The epoxy insulator must fit tightly inside
the column profile.
10.Place the column profile on the profile section on the
connection flange and mount the top end with the epoxy
insulator and the turnable metal part on the already installed
top fixation bracket. Tighten the three screws (pos. A) and
(pos. B) in the desired position.
11.Fit an intermediate fixation bracket to the turnable part welded
on to the profile tube in step 6. Drill holes in the tank wall, fit
screws in the bracket and tightening the screws.
12.Drill the holes for the mounting screws for the crane foot in the
concrete.
13.Mount the crane foot and fit and tighten the screws.
14.Mount the lifting wire (pos. 15) on the pump rack using the
shackle. See fig. 10.

15.Mount the top end of the safety wire to the hole (pos. 31) of
the top fixation bracket by means of a shackle. The other end
of the safety wire ends in a shackle through which the lifting
wire must run.
