5. Installation at Site
5.1 Safety regulations / Special instructions
Electrical equipment operated in hazardous locations must
comply with the explosion protection regulations. This is
indicated on the motor rating plate. If the equipment is
installed in hazardous locations, the applicable local explosion
protection regulations and the regulations of the test certificate
supplied with the equipment and issued by the responsible
approval authorities must be observed and complied with. The
test certificate must be kept close to the location of operation for
easy access (e.g. foreman’s office).
Centrifugal pumps will only give trouble-free operation
when carefully installed and maintained.
N.B.: The pump’s nameplate shown the type series, pump size,
version, product number, main operating data and the works
number (see also 4.2).
Please quote the type series / version in all queries, repeat orders
and particularly when ordering spare parts.
Fig. 5.1-1 Nameplate
This pump / unit must not be operated beyond the limit
values specified on the nameplate for capacity, speed
and temperature or other instructions laid down in this
manual or in the contract documentation. Any data stipulated for
the electrical connection of the unit and instructions for
maintenance and installation must be adhered to without fail.
Operation beyond the conditions indicated above will lead to
overloads the unit cannot withstand.
Trained personnel is essential to ensure trouble-free operation
of the unit.
KSB will not accept any responsibility for the safe and reliable
operation of the pump unit if these operating instructions are not
complied with.
In case of damage or if you need further information, please
contact KSB’s nearest customer service centre.
5.2 Foundation/Checks to be carried out prior to
installation
All structural work required must have been prepared in
accordance with the dimensions stated in the dimension table /
installation plan.
The concrete foundations shall have sufficient strength (min. BN
15) to ensure safe and functional installation in accordance with
DIN 1045 or equivalent standards.
Make sure that the concrete foundation has set firmly before
placing the unit on it. Its surface shall be truly horizontal and
even.
5.3 Installing the Pump / Unit
Before placing the baseplate onto the foundation, make sure that
the concrete foundation is clean and smooth. The complete pump
unit must be aligned horizontally with the help of a precision spirit
level.
Factory alignment of the unit on the baseplate must be re-aligned
after the unit has been mounted on the foundation and after
connecting the piping (precision alignment).
Align the complete pump unit with the help of spirit level placed
on the shaft/discharge nozzle. The correct distance between the
coupling halves as specified in the installation plan must be
observed. Shims shall be fitted between the baseplate / foundation
frame and the foundation itself; they shall always be inserted to
the left and right of the foundation bolts and in close proximity to
these bolts. For a bolt-to-bolt clearance of more than 800 mm,
additional shims must be inserted halfway between the adjoining
holes. All shims must lie perfectly flush.
Tighten the foundation bolts evenly and firmly after the concrete
has set.
It is essential to make sure that the baseplate is
not warped in axial or radial direction.
Proceed with utmost care when aligning the unit, as the pump
unit will only give trouble-free operation when correctly aligned.
Non-compliance with these instructions will lead to forfeiture of
all warranty claims.
Baseplates made of U-rails (up to 400 mm wide) are torsion
resistant in their own right and need not be grouted.
After fastening, baseplates more than 400 mm wide shall be
grouted up to the upper frame edge using low shrinkage concrete,
making sure that no cavities remain.
Close-coupled pumps
It is essential to make sure that the pump is not warped in axial
or radial direction.
If pump and motor are supplied separately, place the pump onto
the foundation without the motor, align with the help of a precision
spirit level (on the upper flange of the drive lantern), then fasten.
Shims shall be fitted between the pump foot and the foundation
itself; they shall always be inserted to the left and right of the
foundation bolts and in close proximity to these bolts. All shims
must lie perfectly flush.
Tighten the foundation bolts evenly and firmly.
