noxious, explosive, hot or other hazardous fluids.
3. If the fluids handled by the pump leave residues which might lead to corrosion
damage when coming into contact with atmospheric humidity, or which might
ignite when coming into contact with oxygen, the pump set must also be
neutralised, and anhydrous inert gas must be blown through the pump for
drying purposes.

The pump is installed in either horizontal or vertical position. It is designed with an
axial fluid inlet and a radial fluid outlet. The hydraulic system is fitted on an
extended motor shaft and the casing is directly bolted to the motor.
The fluid enters the casing via the suction nozzle (1) and is accelerated outward in a
cylindrical flow by the first impeller (2). At the flow contour of the stage casing (3)
the kinetic energy of the fluid is converted into pressure energy and the fluid is
routed to the next impeller (11) via the diffuser (4). This process is repeated in all
stages until the fluid has passed the last impeller (5). The fluid then passes through
the discharge casing (6) to the discharge nozzle (9), where it leaves the pump. The
drive shaft enters the casing at the rear of the last impeller (11). The motor (7) is
bolted to the casing. The shaft passage through the casing is sealed with a dynamic
shaft seal (8). Pumps installed horizontally are mounted on motor feet, whereas
vertically installed pumps are mounted on a pump foot (10).
The pump is sealed by a standardised mechanical seal.

Explosion hazard!
▷Do not install the pump in potentially explosive atmospheres.
▷Observe the information given in the data sheet and on the name plates of the
pump system.
5.2 Checks to be carried out prior to installation
Place of installation
WARNING
Installation on foundations which are unsecured and cannot support the load
Personal injury and damage to property!
▷Make sure the foundation concrete is of sufficient strength (min. X0 to
DIN 1045).
▷Only place the pump set on a foundation whose concrete has set firmly.
▷Only place the pump set on a horizontal and level surface.
▷Refer to the weights given in the general arrangement drawing.
1. Check the structural requirements.
All structural work required must have been prepared in accordance with the
dimensions stated in the outline drawing/general arrangement drawing.
5.3 Piping
5.3.1 Connecting the piping
DANGER
Excessive loads acting on the pump nozzles
Danger to life from leakage of hot, toxic, corrosive or flammable fluids!
▷Do not use the pump as an anchorage point for the piping.
▷Anchor the pipelines in close proximity to the pump and connect them without
transmitting any stresses or strains.
▷Take appropriate measures to compensate thermal expansion of the piping.
CAUTION
Incorrect earthing during welding work at the piping
Destruction of rolling element bearings (pitting effect)!
▷Never earth the electric welding equipment on the pump or baseplate.
▷Prevent current flowing through the rolling element bearings.
NOTE
It is recommended to install check and shut-off elements in the system, depending on the
type of plant and pump. However, such elements must not obstruct proper drainage or
hinder disassembly of the pump.
✓The suction lift line/suction head line has been laid with a rising/downward slope
towards the pump.
5 Installation at Site
Vitastage 17 of 44

✓The nominal diameters of the pipelines are at least equal to the nominal
diameters of the pump nozzles.
✓Adapters to larger diameters have a diffuser angle of approx. 8° to prevent
excessive pressure losses.
✓The pipelines have been anchored in close proximity to the pump and connected
without transmitting any stresses or strains.
1. Thoroughly clean, flush and blow through all vessels, pipelines and connections
(especially of new installations).
2. Before installing the pump in the piping, remove the flange covers on the suction
and discharge nozzles of the pump.
CAUTION
Welding beads, scale and other impurities in the piping
Damage to the pump!
▷Free the piping from any impurities.
▷If necessary, install a filter.
▷Observe the instructions in (⇨ Section 7.2.2.1 Page 29).
3. If required, install a filter in the piping (see illustration: Filter in the piping).

Fig. 3: Filter in the piping
1 Differential pressure gauge 2 Filter
NOTE
Use a filter with laid-in wire mesh (mesh width 0.5 mm, wire diameter 0.25 mm) of
corrosion-resistant material.
Use a filter with a filter area three times the cross-section of the piping.
Conical filters have proved suitable.
4. Connect the pump nozzles to the piping.
CAUTION
Aggressive flushing and pickling agents
Damage to the pump!
▷Match the cleaning operation mode and duration for flushing and pickling
service to the casing and seal materials used.
5.3.2 Permissible forces and moments at the pump nozzles
No piping-induced forces and moments (from warped pipelines or thermal
expansion, for example) must act on the pump.
5 Installation at Site

5.4 Protective equipment
WARNING
The volute casing and casing/discharge cover take on the same temperature as the fluid
handled
Risk of burns!
▷Insulate the volute casing.
▷Fit protective equipment.
5.5 Electrical system
5.5.1 Frequency inverter operation
The pump set is suitable for frequency inverter operation as per IEC 60034-17.
When selecting a frequency inverter, check the following details:
▪Data provided by the manufacturer
▪Electrical data of the pump set, particularly the rated current
▪Ensure short start ramps (max. 5 s)
▪Only start speed-controlled operation after 2 minutes at the earliest.
Pump start-up with long start ramps and low frequency may cause clogging.
Observe the following limits when operating the pump set via frequency inverter:
▪Only utilise up to 95 % of the motor power rating P2 indicated on the name
plate.
▪Frequency range 25-50 Hz
Frequency inverter operation produces RFI emissions whose level varies, depending
on the inverter used (type, interference suppression, make). To prevent the drive
system, consisting of a submersible motor and a frequency inverter, from exceeding
the limits stipulated in EN 50081 always observe the EMC information provided by
the inverter manufacturer. If the inverter manufacturer recommends a shielded
power cable, make sure to use a pump set with a shielded power cable.
The pump set generally meets the interference immunity requirements to EN 50082.
For monitoring the sensors installed the operator must ensure sufficient interference
immunity by appropriately selecting and laying the cables in the plant. No
modifications are required on the power/control cable of the pump set. Suitable
analysing devices must be selected. To monitor the leakage sensor inside the motor,
it is recommended to use a special relay available from KSB.
5.6 Electrical connection
DANGER
Unqualified personnel performing work on the pump set
Danger of death from electric shock!
▷Electrical connection must be effected by a trained electrician only.
▷Observe the regulations stipulated in IEC 30364 (DIN VDE 0100).
WARNING
Incorrect connection to the mains
Damage to the mains network, short circuit!
▷Observe the technical specifications of the local energy supply companies.
1. Check the available mains voltage against the data on the name plate.
2. Select an appropriate start-up method.

5.6.1 Setting the time relay
CAUTION
Switchover between star and delta on three-phase motors with star-delta starting takes
too long
Damage to the pump (set)!
▷Keep switch-over intervals between star and delta as short as possible (see table:
Time relay settings for star-delta starting).

5.6.2 Connecting the motor
NOTE
In compliance with DIN VDE 0530 - Part 8, three-phase motors are always wired for
clockwise rotation (looking at the motor shaft stub).
The pump's direction of rotation is indicated by an arrow on the pump.
1. Change the motor's direction of rotation to match that of the pump.
2. Observe the manufacturer's product literature supplied with the motor.
