5.1 Safety regulations / Special instructions
Electrical equipment operated in potentially
explosive atmospheres must comply with the
relevant explosion protection regulations. This is
indicated on the motor rating plate. If the equipment is
installed in potentially explosive atmospheres, 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 supplied 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 if carefully installed and properly serviced.
Note: The pump’s name plate shows the type series, pump
size, version, main operating data and the works number (see
also section 4.2).
Please quote the type series / version in all queries, repeat
orders and particularly when ordering spare parts.
Fig. 4 Name plate
This unit must not be operated beyond the limit
values for capacity, speed and temperature
specified on the name plate. Make sure that operation is in
accordance with the instructions laid down in this manual
or in the contract documentation. All values stipulated for
electrical connection of the unit as well as instructions
given for installation and maintenance must be adhered to
without fail. Operation of the unit outside the
above-mentioned conditions may result in overloads the
unit cannot withstand.
Skilled, properly trained personnel is essential to ensure
trouble-free operation of the unit.
KSB shall not accept any liability if the instructions set
forth in this manual are not complied with.
In case of damage or if you need further information please
contact our 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 /
general arrangement drawing.
The concrete foundations shall have sufficient strength (min.
class X0) 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 on 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.
It is imperative that the factory-aligned unit mounted on the
baseplate be re-aligned after it has been fastened on the
foundation and after the piping has been connected (precision
alignment).
After placing the pump unit on the foundation, align it with the
help of a spirit level placed on the shaft/discharge nozzle. The
correct distance between the coupling halves as specified in
the general arrangement drawing 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 > 800mm, additional shims shall be
used. All shims must lie perfectly flush.
Fig. 5 Fitting required shims
Tighten the foundation bolts evenly and firmly after 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.
Channel section baseplates (up to 400 mm wide) are
torsion-resistant in their own right; they 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.
To align the pump, 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.
