SHIPPING of PUMPS
- Check whether all materials in delivery list are sent. .
- If there is damage during shipping please notify SEMPOMP Shipping Department
and Transportation company.
- If there are missing materials, immediately inform SEMPOMP Shipping Department.
-. Check whether packaging is damaged during transportation.
- Please carefully take out packaged pump and accessories (if any). Check whether
they are damaged during transportation.
CARRYING
General warnings.
Absolutely obey the following rules during transportation.
-.Use proper wooden crane, forklift, or hoisting mechanisms For unloading or
loading wooden cases, packages, boxes and palettes depending on their weight and
volume.
- Wear gloves, hard tip shoes and helmet during carrying works.

Pump and Motor Group Loading/Unloading
Before lifting pump group please determined the following properties.
- Locations of lifting points
- Total weight and centre of gravity.
-Packaging external dimensions
- During loading/unloading make accelerating and braking operations as it shall not
cause any damage for working personnel.
-Load lifting capacity should be suitable with pump and pump group weight.
- You should never stay under or near lifted load.
- Pump should be hoisted as it is indicated in Figure 1-1 and Figure 1-2 for not
causing any damage in pumps. Motor hanging ring should absolutely not be used
while lifting complete group.
- Load should be kept in lifted position more than required time.
- Pump and pump group should always be lifted and carried in horizontal position
Figure 1-1 Single Pump Figure 1-2 Motopomp
STORAGE
- If pump group is not immediately installed, it should be stored in a place which is
clean dry and does not include freezing and explosion risk.
- If pump bearing are type which should be greased, they should be extra greased for
preventing entry of moisture to bearings around shaft
- Pump should be protected from moisture, dust, dirt and foreign objects by covering
with suitable material. 5
- Pump shaft should be rotated a few turns (e.g once a week) for preventing pitting
around pump bearing surfaces and jamming of shaft.
INSTALLATION
Installation of pump to its place and connection setup should only be done by expert
personnel. Failed installation and pump ground may cause failures.
This situations are not covered with warranty
- If pump is supplied without motor (without motor, proper motor should be selected
prior start to installation of group.
Following properties should be considered during motor selection.
- Maximum power of pump (in all operation ranges)
- Operational revolution of pump shaft
- Necessary power supply
- Motor Type
- Motor connection type ( footed, flanged, horizontal, vertical etc. )
- If pump is purchased as single pump (without motor and chassis); a proper frame
should be constructing for putting this group over it. Frame to be constructed should
have dimensions and strength which will not permit vibration and shape defects.
Starting the motor should be done with control cabinet which is prepared according
to power of motor and floater should absolutely be used for preventing to operate
without water. Also collector diameter should be suitable with pumps efficient
operational ranges not with installation.
Before start to pump installation
- Protecting parts in discharge and suction pumps should be removed and cleaned
well.
-. Pump should be installed in a places which does not have freezing or explosion
risk and have well air conditioning.
- There should be enough space around pump for accessing pump easily and for
maintenance operations and there should be sufficient height and space for lifting
pump if necessary.
- Pump suction pipe should be as short as possible.
- You should be carefully work at pump installation ground preparation and
installation of pump group into its place. Incorrect and careless installation causes
early wearing of pump parts and failures.
6
- Pump ground should be so heavy to absorb vibrations and sturdy to prevent bends
and adjustments defects. Ground concrete should completely be solidified,
completed its plug time and proper stud bolts are placed in pump frame fixing holes
and proper fixing lugs should be placed for using in making connections with welding.
Concrete and plate upper surface should be horizontal and very smooth.
Installation
Installation of pump group to ground by anchoring stud bolts:
- Pump group is placed to center the stud bolt slots which are opened in ground
concrete.
- Anchoring stud bolts are inserted through fixing holes over pump frame fixing holes
and places into their slots.
- Pump group is places over base concrete. Water balance is placed over pump
discharge flange and horizontality of pump is controlled. If there is a horizontal
imbalance in pumps position, steel wedges are put under frame and balance of pump
group is obtained.
- Nuts of anchoring stud bolts are installed.
- Anchoring stud bolt holes are filled with concrete grout.
- Anchoring stud bolts are reciprocally tightened.
- Coupling setup is controlled in this situation.
- Concrete is poured into pump frame. Joining of poured concrete and ground
concrete is cared.
- Complete binding of concrete is controlled and anchoring stud bolts are reciprocally
tightened.
- Coupling adjustment is again controlled with template. If there is maladjustment,
coupling adjustment is made again.
- Discharge and suction flange fixings of pump are controlled again. If there are
unnecessary strains and cricks they are eliminated.
- Coupling guards are placed after coupling adjustment.
:Installation of pump group with concrete fixing plug :
- Pump is placed into ground concrete or the ground to be installed carefully.
7
Pump group frame fixing holes are marked to concrete. Pump group lifted again.
- Marked places where fixing plugs will be placed are drilled carefully according to
standards.
- Fixing plugs are carefully placed into drilled places.
- Steps for installation with anchoring stud bold are made here with same order.
Installation of Pipe Equipment
- Nominal diameter of pump discharge and suction pumps are not an indicator for
correct diameters for discharge and suction pipes. Pipes and accessories having
diameter less than pump opening diameter should absolutely not be used. Especially
bottom backwater valve, dirt retainer, filter and check valves and similar elements
should be chosen to having a larger passing area. Never use pump as a supporting
point for pipe installation or a as a carrier.
-Cricks and stresses in pipe and pipe weight equipments should be controlled
whether they effect pump. For this reason, bolts of discharge and suction flanges
should be loosen and it should be controlled whether pipe system exerts a stress
over pump.
- Never use pumps as a support point or carrier for a pipe installation
-Flow rates generally should not exceed 2m/s in suction pipe and 3 m/s discharge
pipe. High speeds cause decrease in pressure which will cause cavitations
conditions and excess friction losses in discharge pipe.
- Pipe system should be supported from points which are close to pipe
- Pipe connections should be made by flanges. Flanges gaskets should be produced
from suitable material and should have suitable dimensions. Gaskets which will be
used between flanges should be centered for not preventing water flow.
- Proper expansion equipments should be used for preventing additional forces to
pump which may occur because of expansion in systems which operate in over
vibrant and hot liquids.
