1. Use the holes in the feet of the pump set components as template.
2. Determine the position of the holes. Pay attention to offset between stud and
hole in the pump foot.
3. Drill the holes.
5.15 Fastening the baseplate to the foundation
5.15.1 Securing the baseplate with foundation bolts
1. Grout the foundation bolt holes with non-shrinking concrete, compressive
strength class C 25/30, grain size ≤ 8 mm (see Appendix
(
Produce flowability with the help of a solvent.
2. When the grouting compound has set (setting time as indicated by
manufacturer), tighten the nuts of the foundation bolts with the tightening
torque given in the general arrangement drawing.
3. Check coupling alignment and re-align, if necessary.
4. Grouting the baseplate with concrete:
- Prepare the concrete shuttering for the baseplate and foundation pedestals up
to the planned grouting height as shown in the general arrangement drawing.
- Make provisions for the grouting compound to bond with the foundation
concrete.
- Fill at least 1/3 of each field of the baseplate with non-shrinking grouting
compound (e.g. Pagel concrete grout), minimum compressive strength class C
25/30, grain size ≤ 8 mm. The remaining 2/3 of the fields may be filled with
standard concrete of this quality. KSB recommends that all fields be completely
grouted with non-shrinking concrete grout. Produce flowability with the help of
a solvent. Complete grouting without major interruptions.
- In order to avoid cavities, the grouting compound must be compacted.
5. When the grouting compound has set, check the nuts of the foundation bolts
for tight fit once again using a torque wrench.
Observe the tightening torque!
6. Check coupling alignment and re-align, if necessary.
5.15.2 Securing the baseplate with bonded anchors
1. After the curing of the bonded anchors , tighten the nuts of the bonded
anchors with the tightening torque given in the general arrangement drawing.
2. Check coupling alignment and re-align, if necessary.
