Slipping out of the pump / pump unit of the 
transport lifting device can cause damages to 
persons and things.

 

 

4.2 Storage / Conservation 

Pumps or units, which are stored over a longer period 
before start-up (max. 6 months), must be protected 
from moisture, vibrations and dirt (e.g. by wrapping in 

oil paper or plastic). Pumps must basically be stored in 
a place where they are protected from the weather, 
e.g. under dry cover. During this time, all suction and 
discharge branches and all other intakes and outlets 
must be closed with dummy flanges or plugs. 
For longer periods of storage conservation 
measurements at machined surfaces and packing with 
moisture protection can be necessary! 

 

5. Mounting / Installation

5.1 Mounting of Pump / Unit 

 

5.1.1 Mounting of pump on a base frame 

The pump and motor (= pump unit) must be provided 
with a base frame made of steel or cast iron or a 
fabricated (welded) frame, where this does not exist 
already or if it is not included in the delivery. This base 
frame must be placed on a foundation which can 
withstand all loads that arise during operation (refer to 
chapter 5.1.2). 

 

When mounting the pump onto the base frame the 
following must to be noticed: 

 

The base frame must be solid, so that there won’t 
occur any twists or vibrations during the operation. 

 

The mounting surfaces of the pump feet and 
motor on the base frame must be flat (machining 
is recommended). Bracing of the pump leads to 
premature breakdown of the pump and to a loss of 
warranty. 

 

The drillings for the pump mounting must be in 
such a way, that safe fastening is guaranteed. 

 

Between pump and motor shaft an adequate 
space must be left depending on the used 
coupling, refer to chapter 5.3. 

 

Between pump and base frame there must be an 
adequate shimming, so that in the case of 
replacement of the pump the equal height 
between bottom and centreline can be adjusted 
(recommended vertical adjustment 4 to 6 mm). 

 

Align pump and motor, refer to chapter 5.3, as 
well. 

 

5.1.2. Mounting the unit to a foundation 

The place, where the pump is mounted must be 
prepared acc. to the dimensions of the dimensional 
drawings. The concrete foundations should have 
sufficient firmness acc. to DIN 1045 or equal standard 
(min. BN 15), to ensure a secure, functional mounting. 
The concrete foundation must have set, before the 
unit is erected. Its surface must be horizontal and 
even. 

 

 

Sufficient space must be provided for 
maintenance and repair work, especially for 
replacing the drive motor or the complete pump 
unit. The motor fan must be able to take in 
enough cool air, and the intake grille must 
therefore be at least 10 cm away from any wall, 
etc.

 

 

 

For the set of anchor bolts according recesses 
must be provided. If that is not the case, concrete 
expansion bolts resp. epoxy capsule anchor bolts 
can be used. 

 

When mounting the pump on the foundation it 
must be adjusted at the discharge nozzle by 
means of a spirit-level (at discharge nozzle). The 
permitted deviation is 0,2 mm/m. After inserting 
the foundation bolts they must be cast in the 
foundation with concrete. After setting of the grout 
the coupling alignment must be checked 
according chapter 5.3.1 and possible 
misalignments must be corrected by adjusting 
foundation frame in the area of the drive motor. 
The smoothness of the base frame must be 0,2 
mm/m before it is filled up resp. fastened.  For 
adjustment levelling shims or levelling screws 
(optional, not delivered standard  wise) can be 
used. Levelling shims must be inserted next to the 
foundation anchors and must lie plainly. After that 
fasten foundation bolts symmetrically but only 
slightly. Fill in base frame with non shrinking grout.  

 

Notice: 

 

Avoid air bubbles (e.g. by vibrating). 

 

Check that the grout has properly set and 
hardened. 

 

Take care for the after-treatment of the concrete 
acc. to DIN 1045. 

 

After setting, tighten the foundation anchor evenly and 
firmly. Check alignment of coupling acc. to chapter 
5.3.1 and re-adjust, if necessary. Further, check that 
all screws between pump / motor and the base frame 
fit snugly. 
Although the original LS-  resp. LCP-base frames are 
designed solidly, the grouting of the adjusted base 
frames is absolutely necessary. 

 

 

If vibrations are transmitted to the foundation from 
adjoining components, it must be guarded through 
adequate vibration damping padding (vibrations 
from outside can impair the bearing). 

 

To prevent vibrations being transmitted to 
adjoining components, the foundation should be 
laid on a suitable insulating base. 

 

 

The size of these insulating pads will vary, 
depending on circumstances, and should 
therefore be determined by an experienced 
specialist.
