Installation at site

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.
