Fig. 7: Adjusting the levelling elements
The foundation has been prepared in accordance with the dimensions given in the outline
drawing/general arrangement drawing.
1. Position the pump set on the foundation and align it with the help of a spirit level placed on
the shaft and discharge nozzle.
Permissible deviation: 0.2 mm/m.
2. Use shims (2) for height compensation, if necessary.
Always fit shims between the baseplate/foundation frame and the foundation itself; always
insert them to the left and right of the foundation bolts (4) and in close proximity to these
bolts.
For a bolt-to-bolt clearance > 800 mm, fit additional shims (3) halfway between the adjoining
holes.
All shims must lie perfectly flush.
3. Insert the foundation bolts (4) into the holes provided.
4. Use concrete to set the foundation bolts (4) into the foundation.
5. Wait until the concrete has set firmly, then align the baseplate.
6. Tighten the foundation bolts (4) evenly and firmly.
7. Grout the baseplate using low-shrinkage concrete with a standard particle size and a water/
cement ratio of ≤ 0.5.
Produce flowability with the help of a solvent.
Perform secondary treatment of the concrete to DIN 1045.
The installation surface has the required strength and characteristics.
1. Position the pump set on the adjusting elements (4) and align it with the help of
a spirit level (on the shaft/discharge nozzle).
2. To adjust any differences in height, loosen the bolts and locknuts (1,3) of the adjusting
elements (4).
3. Turn the levelling nut (2) until any differences in height have been compensated.
4. Re-tighten the locknuts (1,3) at the adjusting elements (4).
5.3.2 Installation without foundation
NOTE
For low-noise operation contact PUMPIRAN to check whether the pump set can be installed on
anti-vibration mounts.
NOTE
Expansion joints can be fitted between pump and suction/discharge line.
