5.1Safety 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.

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.

5.2Foundation / 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.

5.3Installing 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.

Tighten the foundation bolts evenly and firmly after after the concrete has set.

Caution

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.
